For any procurement manager or chemical engineer sourcing industrial chemicals, the soda ash CAS number is far more than a bureaucratic code. The Chemical Abstracts Service (CAS) registry number uniquely identifies sodium carbonate (Na₂CO₃) as 497-19-8, serving as a universal language that cuts through commercial aliases—from ‘disodium carbonate’ to ‘washing soda’—and local naming conventions. In a market where product identity mix-ups can lead to costly production failures, this numeric fingerprint is the first line of defense in supplier verification, customs clearance, and quality assurance. At Weifang Hailei Fine Chemical Co., Ltd., we embed this identifier into every certificate of analysis, safety data sheet, and shipping document, ensuring that every tonne of dense or light soda ash you receive matches your precise industrial requirements.
Whether you operate a float glass furnace, formulate heavy-duty detergents, or manage flue gas desulfurization at a power plant, knowing the correct CAS number—and how to leverage it during procurement—shields you from adulterated batches, non-compliant imports, and unnecessary detention at port. This guide dissects the science behind soda ash molecular weight, clarifies the soda ash and washing soda difference, and shows you exactly how to vet soda ash for sale offers from an EEAT standpoint, covering everything from regulatory data to real-world application specs.
The soda ash CAS number 497-19-8 acts as a molecular passport for sodium carbonate. In international logistics, regulatory bodies like the European Chemicals Agency (ECHA) and the U.S. Environmental Protection Agency (EPA) use CAS numbers to track substance registrations, manage REACH compliance, and enforce environmental tariffs. For buyers, this means that a supplier’s accurate use of the CAS number on a proforma invoice, bill of lading, and product label is a trust signal. It indicates the supplier operates with the rigor expected under ISO 9001 and REACH frameworks, and that the material will clear customs without demurrage risks.
Misapplying the CAS number—for instance, confusing soda ash with sodium bicarbonate (144-55-8) or caustic soda (1310-73-2)—can trigger off-spec deliveries, dangerous reactions in downstream processes, and even regulatory fines. In one documented case, a detergent plant in Southeast Asia received sodium bicarbonate instead of soda ash because the supplier mixed up the CAS numbers on the shipping manifest, delaying production by three weeks and causing formulation failures that required complete batch disposal. By contrast, specifying your purchase order with both the commercial name and the unambiguous soda ash CAS number closes that risk window, enabling your quality team to cross-reference the CAS number immediately against incoming lot documentation.
Beyond the CAS identifier, soda ash molecular weight—105.99 grams per mole for anhydrous sodium carbonate—is a critical parameter that directly influences stoichiometric calculations in glass batch houses, chemical syntheses, and water softening formulas. When you order soda ash by the metric ton, the molecular weight tells you precisely how much reactive Na₂CO₃ you are buying per unit mass, which in turn drives raw material yield and cost efficiency. For example, in container glass production, an off-spec soda ash with excess moisture or sodium bicarbonate impurity will deliver less available alkali per kilogram, forcing you to over-purchase material to meet the required Na₂O input for melting. That hidden cost can erode margins by 2–4% if not caught during incoming QC.
Professional buyers should use the molecular weight as a benchmark when reviewing supplier certificates of analysis. A high-purity dense soda ash lot should assay at ≥99.2% Na₂CO₃ by weight, meaning that for every 100 kg of product, the effective sodium carbonate mass corresponds to the theoretical molecular weight within a tight tolerance. Weifang Hailei’s in-house testing uses titration against standardized hydrochloric acid and gravimetric loss-on-ignition methods to verify that every shipment conforms to this molecular benchmark, providing you with the data fidelity you need for ISO 17025-accredited audits.

One of the most persistent procurement misunderstandings revolves around the soda ash and washing soda difference. While often used interchangeably in casual conversation, they represent chemically and commercially distinct materials. ‘Soda ash’ generally refers to anhydrous sodium carbonate (CAS 497-19-8) or its monohydrate form (CAS 5968-11-6), whereas ‘washing soda’ is the decahydrate form Na₂CO₃·10H₂O (CAS 6132-02-1) or the generic name for a household cleaning product. Industrial buyers need to be precise: dense and light soda ash grades, as produced by the Solvay or Hou process, are anhydrous and intended for high-temperature manufacturing processes, while commercially available washing soda crystals are typically of much lower purity and contain significant water of crystallization, reducing the effective Na₂CO₃ content to roughly 37%.
For a detergent manufacturer, substituting anhydrous soda ash with decahydrate ‘washing soda’ purchased from a retail channel would be disastrous. The hydrate’s lower alkali content would throw off the surfactant builder system, potentially requiring a 300% mass increase to achieve the same pH and hardness sequestration—completely distorting the formulation cost and physical properties. This distinction is why Every professional request for quotation should explicitly state the desired grade (dense or light), specification compliance (e.g., GB/T 210-2022), and the soda ash CAS number you expect to see on paperwork. When you partner with a dedicated industrial exporter like Hailei Chemical, you receive only anhydrous sodium carbonate that conforms to export-grade purity, eliminating the ambiguity that plagues multi-level reseller channels.
Understanding the soda ash CAS number and molecular weight opens the door to specifying the correct grade for your application. Soda ash’s role is not one-size-fits-all; the dense and light variants differ in bulk density, particle size distribution, and dissolution behavior—each optimized for specific industries.
Flat glass, container glass, and fiberglass producers consume roughly 50% of global soda ash output. Here, dense soda ash with a bulk density of 0.9–1.2 g/cm³ is preferred because it reduces dusting during batch handling and melts uniformly with silica sand at around 1,500°C. The CAS number 497-19-8 must appear on every shipment’s documentation to satisfy glass plant raw material auditing, especially in facilities certified to ISO 14001 or those supplying automotive OEMs. Even small impurities like iron oxide (Fe₂O₃) above 50 ppm can discolor the final product, so top-tier suppliers like Hailei Chemical control iron content through stringent raw brine purification in the ammonia-soda process.
In powdered detergents, light soda ash (bulk density 0.5–0.7 g/cm³) is frequently chosen for its faster dissolution and high surface area, which aids in water softening and alkalinity provision. The molecular weight of 105.99 ensures accurate stoichiometry when reacting with calcium and magnesium ions in hard water. A detergent formulator referencing the soda ash molecular weight can precisely calculate the needed weight percentage to achieve a calcium binding capacity of 200–250 mg CaCO₃ per gram of soda ash, directly matching the performance claims on the retail box. If you have been searching for soda ash for sale that meets detergent industry specifications, our Soda Ash & Baking Soda offer includes both dense and light grades with guaranteed INCI naming and full traceability.
Power plants and waste incinerators inject dry soda ash (usually light grade) into flue gas streams to remove SO₂ and HCl, helping meet increasingly stringent emission limits. The CAS number 497-19-8 must appear in the environmental compliance reports submitted to regulatory authorities, directly linking the abatement performance to the chemical identity. In this context, a soda ash molecular weight verification ensures that the material’s reactivity is consistent, because hydrated or carbonated contaminants would reduce acid neutralization efficiency, potentially causing an exceedance of emission caps. We ship to multiple power generation facilities globally, with packaging options—1-ton FIBCs or 25 kg bags—designed for safe pneumatic conveying into injection silos.
While this guide focuses on soda ash, no discussion of sodium carbonates is complete without acknowledging its sibling, sodium bicarbonate (baking soda, CAS 144-55-8). For food ingredient buyers and pharmaceutical formulators, baking soda is an entirely different substance with unique applications, including its growing popularity for drinking baking soda health benefits. Although not a topic you’ll typically see on a chemical procurement checklist, consumer demand for food-grade sodium bicarbonate solutions—used by some for pH balance or athletic performance—has placed additional purity requirements on B2B suppliers. Food-grade baking soda must comply with FCC, USP, or EU food additive regulation E500(ii), and its CAS number must be strictly segregated from soda ash in your ERP system to prevent dangerous cross-contamination.
Hailei Chemical supplies both soda ash and baking soda under rigorous HACCP and ISO 22000 protocols for food, feed, and pharmaceutical segments. Whether you need bulk quantities of dense soda ash for your glass furnace or food-grade baking soda for a leavening agent application, the same supplier verification logic applies: insist on the correct CAS number, scrutinize the certificate of analysis against industry standards, and demand traceability back to the production batch. For a detailed spec sheet covering both products, explore our Soda Ash & Baking Soda catalog.
When you encounter soda ash for sale offers online, how do you separate a reliable exporter from a superficial trader? Use this five-point checklist to apply EEAT principles to your procurement process:
By adhering to this checklist, you mitigate the risk of receiving off-grade product that can damage your manufacturing process and reputation. Weifang Hailei Fine Chemical Co., Ltd. welcomes such scrutiny and provides full documentation packages with every shipment. Our team can arrange a sample delivery for your lab evaluation—just reach out through our inquiry form for a tailored quotation.
Imagine two containers of white powder arriving at your facility, both labeled only as ‘soda ash,’ but with no CAS number and certificates from different labs. Without the explicit CAS identifier, your QC department must run a full identity test—differential scanning calorimetry (DSC) or diluted acid titration—to confirm anhydrous sodium carbonate, consuming hours that could have been saved by simply requiring the 497-19-8 code on the purchase order. This is why leading chemical distributors in Europe and North America embed the CAS number into digital procurement platforms and automated inventory management systems: it automates receiving inspections and triggers quality hold if a mismatch occurs.
At Hailei Chemical, we have invested in an ERP that syncs the soda ash CAS number with every production lot from the moment it exits the calcination kiln. The molecular weight becomes a real-time process control checkpoint, and the difference between soda ash and washing soda is never blurred because our labeling system prohibits ambiguous trade names. This discipline translates into supply chain resilience for our clients. If you are tired of supplier inconsistencies, we invite you to experience the clarity that an EEAT-oriented chemical partner provides.
Looking beyond the label, smart procurement managers connect the soda ash molecular weight to total delivered cost. Consider freight optimization: dense soda ash, with its higher bulk density, packs more weight per container compared to light soda ash, reducing shipping cost per metric ton of effective Na₂CO₃. By calculating your landed cost using the molecular weight and purity from the COA, you can compare offers on a dry-active-soda-ash basis. For example, an offer of 99.5% purity light soda ash at $200/tonne FOB may actually be more economical than a 98.5% purity dense grade at $195/tonne when you factor in the extra inert mass you are paying to ship and handle. Let the CAS number be your anchor for accurate specification comparison, and let the molecular weight be your calculator for true value.
Our global clients routinely request this level of analytical procurement support. With in-house chemical engineers who speak the language of both lab and logistics, Weifang Hailei Fine Chemical Co., Ltd. helps you model total cost of ownership for your production facility.

For procurement managers and chemical distributors serving the pool and spa industry, understanding the functional difference between baking soda (sodium bicarbonate) and soda ash (sodium carbonate) is not just a matter of chemistry—it’s a daily operational decision. The phrase “baking soda vs soda ash in pool” reflects a common confusion among maintenance crews and a critical sourcing question for bulk buyers. This comprehensive guide breaks down how these two sodium-based alkalis behave in water, which one to use for pH and alkalinity control, and how to secure reliable, high-purity supply at competitive soda ash price per ton levels from a trusted exporter like Hailei Chemical.
Before diving into the baking soda vs soda ash in pool debate, it’s essential to grasp the fundamentals of water balance. Pool water requires careful regulation of two interconnected parameters: pH and total alkalinity (TA). pH measures the acidity or basicity on a scale of 0 to 14, with 7.4 to 7.6 being the ideal range for swimmer comfort and chlorine efficacy. Total alkalinity acts as a pH buffer, preventing rapid oscillations. The recommended TA range is 80–120 ppm.
When pH drifts too low (below 7.2), water becomes corrosive, damaging metal fixtures, etching plaster surfaces, and causing eye irritation. High pH (above 7.8) reduces chlorine’s sanitizing power, promotes scaling, and clouds water. The choice of adjustment chemical—soda ash or baking soda—depends on whether you need to raise pH alone, alkalinity alone, or both simultaneously. Misapplying these chemicals is a common source of costly pool maintenance errors.
Soda ash, chemically known as sodium carbonate (Na₂CO₃), is a powerful alkali used extensively in glass manufacturing, detergent production, and water treatment. In pool chemistry, soda ash is the go-to product for rapidly raising pH with a moderate impact on total alkalinity. Its pH in a 1% solution ranges from 11.3 to 11.6, making it roughly 10 times more basic than baking soda.
When dissolved in water, soda ash dissociates into sodium ions and carbonate ions. The carbonate ions react with hydrogen ions (H⁺) to form bicarbonate (HCO₃⁻), thus consuming acidity and raising pH. For every 10 ppm of soda ash added, you can expect a pH increase of approximately 0.2 units in 10,000 liters of water, while alkalinity rises by about 5–10 ppm. This makes soda ash ideal when pH is dangerously low and TA is within or near the target range.
At Hailei, we supply both dense and light grades of soda ash. For pool chemical formulations, dense soda ash is preferred because it dissolves consistently and is less prone to dusting during handling. Our product boasts a purity of 99.2% min, meeting GB/T 210-2004 and ISO 9001 standards, ensuring predictable dosing and minimal insoluble residue.
Baking soda (NaHCO₃) is a milder alkali with a pH of about 8.3 in a 1% solution. It is universally known as a leavening agent in food and an ingredient in household cleaners, but its role in pool care is distinct: it is the premier choice for raising total alkalinity with only a slight upward nudge to pH. Sodium bicarbonate acts as a buffer, adding bicarbonate ions directly to the water without generating hydroxide ions in significant quantity.
Pool operators often find that TA drifts downward due to the use of acidic sanitizers like trichlor tablets or from rainfall. Adding 1.5 pounds of baking soda per 10,000 gallons of water typically raises TA by 10 ppm. This treatment keeps the buffer system robust so that pH remains stable over time. If you confuse baking soda with soda ash and aim to raise pH quickly, you’ll be disappointed; if you use soda ash when only TA needs correction, you’ll overshoot pH.
For B2B buyers, it is crucial to note that not all sodium bicarbonate is equal. Industrial-grade baking soda for pools and flue gas treatment must comply with strict mesh size and heavy metal limits. Hailei’s baking soda meets the highest export specifications, with purity ≥99.0%, low chloride content, and consistent particle distribution, making it suitable for direct use or further blending into multi-functional pool products.
The core of the “baking soda vs soda ash in pool” question lies in the chemical composition and resultant water chemistry impact. Here is a concise breakout that every procurement professional should have on hand when advising downstream clients or formulating proprietary blends:
These differences drive purchasing decisions. A commercial pool chemical distributor typically stocks both products and packages them under different label claims. Knowing when to recommend one over the other reduces liability and builds trust with professional pool operators.
Use soda ash (sodium carbonate) when:
Use baking soda (sodium bicarbonate) when:
In practice, many commercial pools use a combination. A procurement specialist might witness facility managers buying both chemicals by the pallet. For those selling pre-measured pool kits, offering a dual-pack of soda ash and baking soda under separate names can differentiate your brand. Our Hailei team often supports blend formulators with consistent, high-purity raw materials.
For anyone searching “soda ash price per ton,” the chemical market presents a dynamic landscape. As of early 2025, the export price of dense soda ash FOB China ranges widely depending on purity, packaging, and contract volume. Buyers can expect benchmark prices between $200 and $350 per metric ton for standard 99.2% min dense soda ash. Light soda ash usually commands a slight premium due to specific industrial demand. Factors influencing soda ash market price include energy costs (synthetic ash production relies heavily on thermal energy), shipping freight rates, and seasonal demand from glass and detergent sectors.
For pool chemical buyers, the soda ash price per ton is just one component of total acquisition cost. Hailei Chemical helps customers reduce total cost of ownership by offering flexible shipment terms (FOB Qingdao, CIF major ports), optimized container loading (up to 25 MT in a 20-foot container), and consistent quality that eliminates rework. Long-term contracts can stabilize pricing against volatile soda ash market price fluctuations, a strategy many pool chemical distributors adopt to offer stable retail pricing to their service customers.
When comparing soda ash vs baking soda for laundry or other applications, note that baking soda market prices are historically higher, typically $300–$450 per ton FOB for food/feed grade, due to refining steps and purity demands. This pricing reality reinforces why soda ash is the chemical of choice for pH adjustment where high alkalinity surge is tolerable.
While this is an industrial sourcing guide, the frequently searched query “how to make soda ash for tie dye with baking soda” has an interesting parallel to pool maintenance. Some resourceful pool owners have attempted to convert baking soda into soda ash to save a trip to the chemical store. The process involves heating sodium bicarbonate in an oven at 200°C (400°F) for about an hour. The heat drives off carbon dioxide and water, producing sodium carbonate:
2 NaHCO₃ (heat) → Na₂CO₃ + CO₂ + H₂O
While this chemistry is sound, the resulting homemade soda ash is amorphous and may contain unconverted bicarbonate. For tie dye or craft projects, that inconsistency is tolerable. For a 50,000-gallon commercial pool, however, the risk of unpredictable pH swing makes DIY conversion impractical and potentially dangerous. Instead, sourcing high-quality, factory-produced soda ash ensures exact dosing—and when purchased at scale, the soda ash price per ton erases any imagined savings. For bulk soda ash that fits your production, explore our product specifications.
The laundry detergent industry is one of the largest consumers of soda ash, and the “soda ash vs baking soda for laundry” discussion shares chemical roots with pool treatment. Soda ash is a key builder in powder detergents; it softens water by precipitating calcium and magnesium ions, allowing surfactants to work more effectively. Baking soda, on the other hand, is a mild deodorizer and pH buffer in laundry boosters. The chemical behavior is analogous: soda ash delivers a high-pH environment that breaks down acidic soils, while baking soda modifies alkalinity gently.
For pool chemical formulators who also serve the industrial cleaner market, understanding these parallel applications broadens procurement strategies. Purchasing soda ash in bulk for multiple applications—laundry detergent manufacture and pool pH adjustment—can consolidate supply chains and improve the soda ash price per ton through larger volume commitments. Hailei Chemical’s dense soda ash meets the stringent requirements for both glass manufacturing and detergent production, offering an attractive multi-industry solution.

Soda ash and baking soda are two of the most versatile industrial chemicals, powering everything from glass manufacturing and detergent production to flue gas treatment and food leavening. For procurement managers and chemical engineers, understanding the differences, conversion chemistry, and sourcing strategies for these sodium compounds is essential. This comprehensive guide provides a deep dive into soda ash (sodium carbonate) and baking soda (sodium bicarbonate), covering their industrial applications, health benefits, and how to secure reliable bulk supplies from a trusted supplier like Weifang Hailei Fine Chemical Co., Ltd.
If you’ve ever asked, ‘What is soda ash?’ you’re not alone. Soda ash, chemically known as sodium carbonate (Na₂CO₃), is a white, odorless powder that is primarily used in the glass industry, detergent manufacturing, and water treatment. It is commercially available in two main forms:
Baking soda (sodium bicarbonate, NaHCO₃) is a milder alkali with a slightly salty, alkaline taste. It decomposes when heated, releasing carbon dioxide, a property that makes it invaluable as a leavening agent in food, a fire extinguisher component, and a flue gas treatment reagent. While both chemicals are sodium salts, their pH, reactivity, and industrial roles differ significantly. Soda ash provides strong alkalinity for industrial processes, whereas baking soda offers controlled alkalinity and gas release for consumer and pharmaceutical applications.
A common question among hobbyists and small-scale operators is ‘how to convert baking soda to soda ash’. The answer lies in simple thermal decomposition. When baking soda is heated above 80°C (or more rapidly at 200°C), it breaks down into soda ash, water, and carbon dioxide according to the reaction:
2 NaHCO₃ (s) → Na₂CO₃ (s) + H₂O (g) + CO₂ (g)
This laboratory-scale conversion is sometimes used to produce small amounts of soda ash for niche applications. However, for industrial buyers, it is crucial to understand that large-scale soda ash production does not rely on this method. Instead, soda ash is manufactured either by the Solvay process (from salt and limestone) or by mining and refining trona ore. Conversely, baking soda is commercially produced by reacting soda ash with carbon dioxide and water. Thus, the industrial supply chain flows from soda ash to baking soda, not the reverse. Procurement professionals should source each chemical directly from primary manufacturers to ensure purity, consistency, and cost-effectiveness.
Both soda ash and baking soda play indispensable roles across a wide range of industries. Understanding where each excels helps buyers select the right grade and quantity.
Soda ash is a critical flux in glass production, lowering the melting temperature of silica and reducing energy consumption. Dense soda ash is preferred because it minimizes dust, improves furnace efficiency, and yields high-clarity glass for containers, flat glass, and fiberglass. Our dense soda ash meets industry standards with a purity of Na₂CO₃ ≥ 99.2%, iron content below 35 ppm, and consistent particle distribution.
Light soda ash serves as a builder in laundry powders and industrial cleaners, softening water and enhancing surfactant performance. Baking soda is added to eco-friendly cleaning formulations as a gentle abrasive and deodorizer. Both chemicals must meet stringent heavy metal limits and dissolution rates for formulators.
Baking soda is increasingly used in dry sorbent injection systems for removing acid gases (SO₂, HCl) from power plant and incinerator flue gases. Its high specific surface area and reactivity make it an effective and cost-efficient alternative to lime, helping plants meet environmental compliance. We supply fineness-controlled sodium bicarbonate grades specifically engineered for flue gas treatment.
For food ingredient buyers, baking soda is a ubiquitous leavening agent in baked goods, as well as a pH regulator and antacid. Our food-grade baking soda complies with FCC, USP, and EU E500(ii) standards, guaranteeing safety and consistent performance. It is also used as a buffering agent in animal feed.
The term ‘health benefits baking soda’ typically refers to its uses as an antacid to relieve heartburn and indigestion, an oral care ingredient, and even a performance supplement for athletes. For industrial buyers supplying the pharmaceutical and nutraceutical sectors, these benefits translate into strict quality demands. Pharmaceutical-grade sodium bicarbonate must have a purity of 99.0–100.5%, low arsenic and heavy metal levels, and consistent particle size for tablet compression. In animal nutrition, baking soda acts as a rumen buffer in dairy cattle, improving feed efficiency and milk fat yield.
Sourcing from a reliable bulk baking soda supplier that provides Certificate of Analysis (CoA) and traceable batch numbers is essential to ensure these health-related applications are safe and effective. Hailei Chemical offers food, feed, and pharmaceutical grades with full documentation.
