Continue reading to learn about the sodium sulphate symbol, whether its solution is acidic or alkaline (ph of sodium sulphate), how it works as a drying agent, and what you can expect for the sodium sulphate price per kg when importing from China.

What Is Sodium Sulphate? Chemical Identity and Hindi Terminology

Sodium sulphate is an inorganic salt with the sodium sulphate symbol Na₂SO₄, representing two sodium cations for every sulphate anion. It occurs naturally in mineral deposits (thenardite for anhydrous, mirabilite for decahydrate) and as a by-product of chemical processes like rayon manufacturing or hydrochloric acid production. Industrially, the anhydrous form (CAS 7757-82-6) dominates due to its high active content and low shipping weight. The decahydrate (Glauber’s salt, Na₂SO₄·10H₂O) is less common in bulk B2B trade because of its high water content.

For Hindi-speaking plant operators and local traders, what is sodium sulphate in Hindi translates to सोडियम सल्फेट (pronounced sodiyam salfate). In some regions, especially when used in detergents, it’s colloquially called डिटर्जेंट पाउडर का फिलर (detergent powder filler). Historically, the decahydrate was known as ग्लॉबर नमक (Glauber’s salt). This linguistic clarity prevents confusion with other sodium salts like sodium carbonate (सोडा ऐश) or sodium bicarbonate (बेकिंग सोडा) during procurement.

Sodium Sulphate Symbol and Molecular Weight

The sodium sulphate symbol Na₂SO₄ indicates a molecular weight of 142.04 g/mol for the anhydrous form. Industrial-grade material typically has a purity of 99% minimum (on dry basis), with key impurities being chlorides (≤0.35% as NaCl), iron (≤0.002%), and water-insoluble matter (≤0.05%). Our technical data sheet at sodium sulphate product page provides full specifications. When buying, always verify the assay report to ensure that the sodium sulphate price per kg reflects the true active content, not just the bulk weight.

Why Sodium Sulphate Is Used as a Drying Agent

One of the frequently asked technical questions is why sodium sulfate a drying agent—particularly in organic synthesis and laboratory workflows. The anhydrous form has a strong affinity for water, forming the stable decahydrate (Na₂SO₄·10H₂O) when exposed to moisture. This hydration process is rapid, exothermic, and reaches an equilibrium that effectively removes traces of water from organic solutions without reacting with the compounds. As a granular drying agent, sodium sulfate offers several advantages:

However, its drying efficiency decreases above 32°C, where the decahydrate begins to melt in its own water of crystallization. For this reason, in industrial drying of solvents, it is often used at ambient temperatures. Understanding why sodium sulfate a drying agent helps chemical manufacturers select the right desiccant for their specific process conditions. Our 99% pure sodium sulphate is suitable not only as a filler but also as a reliable laboratory and industrial drying medium.

The pH of Sodium Sulphate: Acidic, Alkaline, or Neutral?

Another critical specification for formulation chemists is the ph of sodium sulphate. Aqueous solutions of pure sodium sulphate are essentially neutral, with a pH in the range of 6.0–8.0 for a 5% solution at 25°C. This neutrality arises because sodium sulphate is a salt of a strong acid (sulfuric acid) and a strong base (sodium hydroxide). Neither ion hydrolyzes significantly in water, so the solution does not shift the pH appreciably. However, industrial grades may show a slightly acidic pH (5.0–6.5) due to residual free acid from manufacturing, or a slightly alkaline pH (8.0–9.5) if neutralized with soda ash. At Hailei Chemical, we control the ph of sodium sulphate within 6.5–7.5 for our standard 99% material, ensuring compatibility with detergent enzymes and textile dye baths. Always specify your pH tolerance when requesting a quote, especially for sensitive applications like reactive dyeing where a stable neutral pH prevents color variation.

Key Industrial Applications of Sodium Sulphate

Knowing what is sodium sulphate in Hindi is not enough—you need to understand exactly where it fits in your production. Here are the four major industrial uses:

1. Detergent Powder Filler

Sodium sulphate acts as an inert, free-flowing filler in laundry detergent powders. It helps dilute the active surfactant system to a cost-effective bulk density, improves powder flowability, and prevents caking. A typical heavy-duty detergent contains 20–40% sodium sulphate by weight. For Indian and South Asian detergent brands, where price sensitivity is high, importing high-purity yet competitively priced Chinese सोडियम सल्फेट is a critical business decision. Our product matches the whiteness and bulk density requirements of leading detergent formulations.

2. Glass Manufacturing

In the glass industry, sodium sulphate serves as a fining agent and flux. It helps remove gas bubbles from the molten glass and promotes the decomposition of silica. Approximately 3–5% sodium sulphate is added to the batch in container glass and flat glass production. The anhydrous form prevents unwanted water introduction into the furnace. Glass plants require a consistent purity and particle size; our sodium sulphate meets the Chinese national standard GB/T 6009-2014 Type I.

3. Textile Dyeing Auxiliary

As a dyeing auxiliary, sodium sulphate acts as a levelling agent and exhaust agent for direct, reactive, and sulphur dyes. It reduces the solubility of the dye in water, driving it onto the fabric for uniform coloration. The optimal ph of sodium sulphate here is near neutral to avoid affecting the dye-fiber reaction. Textile mills in India and Bangladesh use substantial tonnages; we understand your seasonality and just-in-time delivery needs.

4. Kraft Paper Pulping

In the kraft (sulphate) pulping process, sodium sulphate is used as a makeup chemical in the recovery cycle. It is added to black liquor before firing in the recovery boiler, where it is reduced to sodium sulphide—essential for the cooking liquor. Pulp and paper producers require low-moisture anhydrous sodium sulphate to avoid energy loss in the boiler. Our product is shipped with moisture below 0.3%.

Sodium Sulphate Price Per Kg: Factors That Influence Cost

Procurement managers often search for the sodium sulphate price per kg as a quick benchmark. However, the price varies significantly based on purity, packaging, quantity, and incoterms. Here’s what shapes the sodium sulphate price per kg for B2B buyers:

As a rough indication, bulk export pricing for 99% sodium sulphate from China can range from $0.10 to $0.20 per kg FOB, depending on the factors above, but this does not constitute a quote.

Shipping and Logistics: Safely Importing Sodium Sulphate from China

Anhydrous sodium sulphate is non-flammable, non-hazardous (UN not regulated for transport), making it straightforward to ship. However, proper packaging is critical to prevent moisture absorption during ocean transit. Standard practice includes a moisture-proof PE liner inside polypropylene woven bags, stacked on fumigated wooden pallets for breakbulk or containerized loads. For Indian importers, the most common route is FCL 20′ containers carrying 25–27 tons net from Qingdao or Shanghai ports to Mumbai, Mundra, or Chennai. Transit time is approximately 15–25 days, plus customs clearance. We help buyers manage documentation, including Certificate of Origin (Form E for India-APTA preferential tariff), to reduce import duties. Our logistics team can coordinate door-to-door delivery if you prefer a hassle-free experience. Knowing what is sodium sulphate in Hindi helps your plant floor, but knowing how to get it there on time and on budget is equally vital.
