Sodium Sulfate
Sodium Sulfate (Product Code: SCI-430/172) is an analytical reagent grade sodium salt used as a neutral electrolyte in water electrolysis, as a sulfate source in analysis and, in its anhydrous form, as a drying agent for organic liquids in school and college laboratories. Lab technicians and chemistry teachers receive it in a 200 g pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

What Is Sodium Sulfate Used For?
Pure water conducts electricity poorly, so a little sodium sulfate is dissolved in it before electrolysis in a Hoffman voltameter. The salt carries the current without being used up: hydrogen collects at the cathode and oxygen at the anode in a two-to-one volume ratio, and a few drops of universal indicator reveal alkali forming around one electrode and acid around the other.
Because it comes from a strong acid and a strong base, its solution is close to neutral, which makes it the control salt when students compare the pH of different salt solutions. In organic practicals the anhydrous form is swirled into a wet organic layer after separation in a separating funnel, where it takes up dissolved water and clumps until the liquid is dry. Its solution also gives the white barium sulfate precipitate in the sulfate test.
What to Specify When Ordering
- Whether you need the anhydrous form for drying organic liquids, so we can confirm the form of the batch offered.
- The number of 200 g packs for each laboratory.
- Companion apparatus, such as a water electrolysis apparatus or separating funnel, for the same quotation.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, sources Sodium Sulfate for school, college and technical-training laboratories and supplies it in 200 g packs with the MSDS. The same enquiry can include electrolysis apparatus, separating funnels and indicators, which helps a department restock several practicals at once, in India or in international markets. See the ScienceLab profile for company details.

Frequently Asked Questions
Why is Sodium Sulfate added to water for electrolysis?
Sodium Sulfate is added because pure water conducts electricity poorly. Its ions carry the current while the water itself is split into hydrogen and oxygen, and the sodium and sulfate ions stay in solution, so the gases collected come from the electrolysis of water.
Can Sodium Sulfate SCI-430/172 be used as a drying agent?
Sodium Sulfate dries organic liquids only in its anhydrous form. The listing for Sodium Sulfate SCI-430/172 states analytical reagent grade and a 200 g pack but not the hydration state, so ask us to confirm the form before ordering it for drying work.
Is Sodium Sulfate solution neutral?
Yes, a Sodium Sulfate solution is close to neutral, because the salt is formed from a strong acid, sulfuric acid, and a strong base, sodium hydroxide. That makes it a useful reference when students compare acidic, neutral and alkaline salt solutions.
How should Sodium Sulfate be stored?
Keep Sodium Sulfate SCI-430/172 tightly closed in a dry cabinet, because moisture from the air can make the salt cake. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Is Sodium Sulfate available in a smaller pack?
Yes. Besides Sodium Sulfate SCI-430/172 in a 200 g pack, the catalogue lists Sodium Sulfate in a smaller pack under its own code, which suits laboratories that use only occasional amounts. State the code you want in your enquiry.
Who supplies Sodium Sulfate SCI-430/172?
Sodium Sulfate SCI-430/172 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and delivers it with its MSDS to schools, colleges, training institutes and dealers in India and international markets.
