What is Sodium Sulphate in Hindi? A Comprehensive Guide for Industrial Buyers | Hailei Chemical
If you’re searching for what is sodium sulphate in Hindi, chances are you’re a procurement professional, a chemical engineer, or an industrial buyer trying to get a handle on this essential inorganic compound. In Hindi, it’s सोडियम सल्फेट (Sodium Sulphate in Hindi), and when hydrated, it’s sometimes called ग्लॉबर सॉल्ट. Sodium sulphate (Na₂SO₄) is a white, crystalline powder with a surprisingly broad range of uses: a filler in detergent powders, a flux in glass manufacturing, a levelling agent in textile dyeing, and a pulping chemical in kraft paper production. With over 15 years of experience exporting high-purity sodium sulphate from China, Weifang Hailei Fine Chemical Co., Ltd. knows the technical and commercial details that keep industrial buyers up at night. This guide walks you through the chemical fundamentals, real-world applications, pricing factors, and quality specs you need to make smart sourcing decisions.
Understanding what is sodium sulphate in Hindi is particularly useful for buyers in the Indian subcontinent, where Hindi and regional languages are common on the plant floor. Bridging that language gap helps technical and purchasing teams get on the same page with global standards. Keep reading to learn about the sodium sulphate symbol, whether its solution is acidic or alkaline (ph of sodium sulphate), why 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—two sodium cations for every sulphate anion. It occurs naturally in mineral deposits (thenardite for the anhydrous form, mirabilite for the decahydrate) and as a by-product of processes like rayon manufacturing or hydrochloric acid production. For industrial use, the anhydrous form (CAS 7757-82-6) dominates because of its high active content and lower shipping weight. The decahydrate (Glauber’s salt, Na₂SO₄·10H₂O) is less common in bulk B2B trade; it’s mostly water by weight, and that adds up fast when you’re paying freight.
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 in the detergent sector—it’s colloquially called डिटर्जेंट पाउडर का फिलर (detergent powder filler). Historically, the decahydrate was known as ग्लॉबर नमक (Glauber’s salt). Getting this terminology right prevents confusion with other sodium salts like sodium carbonate (सोडा ऐश) or sodium bicarbonate (बेकिंग सोडा) during procurement. A common mistake is ordering the wrong salt because someone on the team used the wrong Hindi term—don’t let that be you.
Sodium Sulphate Symbol and Molecular Weight
The sodium sulphate symbol Na₂SO₄ gives a molecular weight of 142.04 g/mol for the anhydrous form. Industrial-grade material typically runs at 99% minimum purity (on dry basis), with key impurities kept tight: chlorides ≤0.35% as NaCl, iron ≤0.002%, and water-insoluble matter ≤0.05%. Our technical data sheet at sodium sulphate product page has the full specs. When you’re buying, always verify the assay report. Here’s the thing: the sodium sulphate price per kg should reflect the true active content, not just the bulk weight. Experienced procurement teams know that a lower price per ton can be a false economy if the purity is off.
Why Sodium Sulphate Is Used as a Drying Agent
One of the most frequent technical questions is why sodium sulfate a drying agent—especially in organic synthesis and laboratory workflows. The anhydrous form has a strong affinity for water, forming the stable decahydrate (Na₂SO₄·10H₂O) when it picks up moisture. This hydration is rapid, exothermic, and reaches an equilibrium that effectively pulls traces of water from organic solutions without reacting with the compounds. As a granular drying agent, sodium sulphate brings several advantages:
- High water absorption capacity: up to 1.25 g water per gram of Na₂SO₄
- Chemically inert toward most organic substances
- Easy removal by filtration after drying
- Cost-effective compared to molecular sieves or magnesium sulfate in bulk applications
But there’s a catch. Its drying efficiency drops above 32°C, where the decahydrate starts to melt in its own water of crystallization. So in industrial solvent drying, it’s typically used at ambient temperatures. Understanding why sodium sulfate a drying agent helps chemical manufacturers pick the right desiccant for their specific process. Our 99% pure sodium sulphate is suitable not just as a filler but also as a reliable laboratory and industrial drying medium. In practice, we’ve seen it used in everything from solvent recovery systems to specialty chemical manufacturing.
The pH of Sodium Sulphate: Acidic, Alkaline, or Neutral?
Another critical spec for formulation chemists is the ph of sodium sulphate. Aqueous solutions of pure sodium sulphate are essentially neutral, with a pH in the 6.0–8.0 range for a 5% solution at 25°C. That neutrality comes from it being a salt of a strong acid (sulfuric acid) and a strong base (sodium hydroxide). Neither ion hydrolyzes much in water, so the solution doesn’t shift pH appreciably. However, industrial grades can 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. A buyer once told us they lost an entire batch of fabric because the pH was off by just 0.5 units. Don’t let that happen.
Key Industrial Applications of Sodium Sulphate
Knowing what is sodium sulphate in Hindi is just the start. You need to see exactly where it fits in your production. Here are the four major industrial uses, with some real-world numbers:
1. Detergent Powder Filler
Sodium sulphate is the workhorse filler in laundry detergent powders. It dilutes 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 razor-thin—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. We’ve seen plants run 24/7 on our material without a single flow issue.
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. Typically, 3–5% sodium sulphate is added to the batch in container glass and flat glass production. The anhydrous form is preferred because it doesn’t introduce water into the furnace—water can cause defects in the final product. Glass plants demand consistent purity and particle size; our sodium sulphate meets the Chinese national standard GB/T 6009-2014 Type I. One flat glass producer we work with has been using our material for six years without a single rejected shipment.
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 even coloration. The optimal ph of sodium sulphate here is near neutral to avoid messing with the dye-fiber reaction. Textile mills in India and Bangladesh use substantial tonnages—we’re talking thousands of metric tons a year for some operations. We understand your seasonality and just-in-time delivery needs. A common mistake is assuming all sodium sulphate is the same; but particle size and pH consistency matter a lot in dyeing.
