What is Sodium Sulphate in Hindi? सोडियम सल्फेट का परिचय

In answer to “what is sodium sulphate in Hindi?”, the chemical name सोडियम सल्फेट refers to an inorganic compound with the formula Na2SO4. It appears as a white crystalline powder or granules, highly soluble in water, and is commercially available in two main forms: anhydrous (Na2SO4) and decahydrate (Na2SO4·10H2O), also known as Glauber’s salt. For Indian industries—especially detergent manufacturers in Gujarat, glass plants in Maharashtra, and textile mills in Tamil Nadu—the anhydrous grade with minimum 99% purity, such as the product we supply at bulk sodium sulphate, is the preferred choice because of its high filler efficiency, consistent particle size, and low moisture content.

Historically, सोडियम सल्फेट has been known as “salt cake” when produced via the Mannheim process, but modern synthetic and natural sources yield very pure material. Whether you call it sodium sulfate, sodium sulphate, or सोडियम सल्फेट, understanding its chemical identity is the first step in leveraging its full potential for your manufacturing needs.

Sodium Sulphate Symbol and Chemical Properties

Every chemical procurement decision starts with precise specifications. The sodium sulphate symbol is Na2SO4, indicating it contains two sodium cations (Na+) and one sulfate anion (SO42−). This simple ionic structure is responsible for its remarkable stability and versatility. Key chemical properties relevant for industrial buyers include:

• Molecular weight: 142.04 g/mol (anhydrous)
• Appearance: White, odorless, hygroscopic powder
• Melting point: 884 °C
• Solubility in water: 4.76 g/100 mL at 0 °C, rising to 42.7 g/100 mL at 100 °C, with maximum solubility around 32.4 °C—a critical property for detergent manufacturing where temperature-controlled dissolution is used.
• pH of sodium sulphate: Aqueous solutions are essentially neutral, typically between 6.0 and 7.5, because the compound is a salt of a strong acid (sulfuric acid) and a strong base (sodium hydroxide). This neutral pH ensures compatibility with sensitive formulations in textile dyeing and papermaking.

For Indian importers, knowing the chemical symbol and these fundamental characteristics simplifies customs documentation, quality control checks, and technical discussions with suppliers. Always request a Certificate of Analysis (COA) when procuring high-purity sodium sulphate to verify that Na2SO4 content meets the 99% threshold you need.

Why Sodium Sulfate is Used as a Drying Agent

One of the lesser-known but highly valued functions in chemical processing is the ability of anhydrous sodium sulfate to act as a desiccant. Many buyers in India’s pharmaceutical and fine chemical sectors ask: why sodium sulfate a drying agent? The answer lies in its hygroscopic nature and the stable hydrate formation. Anhydrous Na2SO4 readily absorbs water molecules to form the decahydrate, Na2SO4·10H2O, effectively removing moisture from organic solvents or reaction mixtures. Unlike calcium chloride, sodium sulfate is chemically inert, meaning it won’t react with most organic compounds, and it leaves a clean, neutral residue that is easy to filter out.

In practice, this makes sodium sulfate the drying agent of choice for laboratory and pilot-scale organic synthesis, as well as certain industrial drying processes where high-purity anhydrous Na2SO4 is used to dry air or inert gases. For Indian chemical manufacturers, sourcing this material from a trusted sodium sulphate supplier like Hailei Chemical ensures you receive a product with guaranteed low moisture content (typically <0.1%), ready for both large-scale drying applications and as a filler/diluent in formulations.

pH of Sodium Sulphate: A Neutral Salt for Stable Processes

Understanding the pH of sodium sulphate is crucial when incorporating it into pH-sensitive industrial processes. As an ionic salt derived from a strong acid and strong base, sodium sulphate dissolves to give a solution with a pH close to 7.0. This neutrality has significant operational benefits:

• Detergent manufacturing: A neutral filler prevents unintended shifts in alkalinity that could affect enzyme activity or bleach stability in modern detergent powders.
• Textile dyeing: As a levelling agent, sodium sulphate must buffer the dye bath without altering the pH required for specific dye-fiber interactions—neutral Na2SO4 maintains the intended pH window.
• Paper pulping: In kraft recovery processes, sodium sulphate is reduced to sodium sulfide in the black liquor cycle; a neutral pH starting material minimizes side reactions that could corrode equipment.

For Indian mills and factories, monitoring the pH of incoming sodium sulphate batches is a standard quality gate. Hailei Chemical’s anhydrous sodium sulphate consistently delivers a 1% solution pH of 6.0–7.5, tested per GB/T 6009-2014 methods, giving you confidence in every shipment.

Sodium Sulphate Price Per Kg in India: Factors and Market Trends

One of the most frequently searched terms by procurement teams is sodium sulphate price per kg. Pricing for industrial-grade anhydrous sodium sulphate is dynamic and influenced by multiple factors. As of the current market, Indian buyers can expect landed costs ranging from approximately INR 15 to INR 40 per kilogram, depending on quantity, purity, and origin. However, focusing solely on price per kg can be misleading; a holistic cost analysis is essential.

Key factors affecting the sodium sulphate price per kg for Indian importers:

• Purity grade: 99% pure synthetic sodium sulphate commands a premium over natural 92–98% grades. In applications like high-quality transparent glass or premium detergents, the extra cost translates to better product clarity and performance.
• Order volume: Bulk shipments of 25–50 metric tons via sea freight to Nhava Sheva or Mundra port significantly reduce the per-kg price compared to 1-ton lots.
• Logistics costs: Shipping from China to Indian west coast ports typically adds INR 2–5 per kg, but Hailei Chemical’s consolidated container loads help mitigate these expenses.
• Exchange rate fluctuations: The INR-USD exchange rate directly impacts import costs, making forward contracts a smart move for regular buyers.

Experienced procurement teams know that the cheapest per-kg price often hides hidden costs: inconsistent purity, moisture above 0.5%, or delayed shipments that halt production lines. At Hailei Chemical, our pricing is competitive yet transparent—we provide a full breakdown of FOB, freight, and insurance costs so you can calculate true landed costs.

Practical Procurement Tips for Indian Industries

Whether you are sourcing for a detergent plant in Silvassa or a glass furnace in Firozabad, a few practical steps can streamline your sodium sulphate procurement:

• Specify your grade clearly: Anhydrous Na2SO4 for detergents requires 99% minimum purity, while lower grades (92–95%) may suffice for certain paper pulping applications. Always match the grade to your process.
• Request a COA upfront: A Certificate of Analysis from the supplier should include Na2SO4 content, moisture, pH, and particle size. Hailei Chemical provides this with every shipment.
• Plan for lead times: Sea freight from China to India takes 14–21 days. Keep a safety stock of at least 2–3 weeks to avoid production stoppages.
• Consider packaging: Sodium sulphate is typically supplied in 25 kg or 50 kg bags, or 1-ton jumbo bags. For automated dosing systems, specify bag type and dimensions.
• Test a sample first: Before committing to a large order, request a 5 kg sample for in-house evaluation. Hailei Chemical offers free samples to qualified buyers.

A common mistake is assuming all sodium sulphate is the same. It is not. The crystal morphology, bulk density, and flowability vary between synthetic and natural sources, directly affecting your mixing and handling processes. Our product is engineered for consistent flow and dispersion.
