Product Code : SCL-LC-12203
Sodium Sulphate (SKU SCL-LC-12203), also written sodium sulfate, is an inorganic sodium salt for sulphate-salt studies, solution preparation, solubility and crystallisation work, and method-specific drying steps. It suits supervised school labs, college practicals and analytical and research laboratories. For schools, colleges, training institutes, tender contractors and distributors, Science Lab Supplies, a laboratory chemicals supplier in India, quotes and packs this salt at Ambala.
Specifications
Both sodium sulphate forms, with their formulas and molecular weights, sit in separate rows of the table, followed by handling and storage. In short, it is an odourless white crystalline solid or powder: anhydrous Na2SO4 weighs about 142.04 g/mol and the decahydrate about 322.20 g/mol; the form, grade and net weight appear on the label and quotation.

Applications and Experiments for Sodium Sulphate
Mixed with barium chloride solution, sodium sulphate gives a barium sulphate precipitate, an example of a double-displacement reaction. It can also be used to study solubility and crystallisation of sulphate salts and for drying or reagent steps wherever an approved method specifies sodium sulphate.
- Class 10 chemistry: double-displacement and precipitation with barium chloride.
- Salt analysis: sulphate-ion practice and reference solutions.
- Solubility and crystallisation studies with hydrated and anhydrous forms, using a 90 mm glass Crystallizer.
- B.Sc. organic chemistry: drying steps for extracts separated in a 500 ml Separator Funnel, where the method names sodium sulphate.
Standard Scope of Supply
You receive the sodium sulphate container in the quoted pack size, labelled with batch, grade and hydrate form, plus the Safety Data Sheet and outer packaging with a tamper seal and export documentation. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Quotes are available for a single pack or for stock across many school labs, each setting out packing, delivery time and price for the amount you name. Barium chloride and other school chemistry lab equipment in India can go on the same quote for complete precipitation practicals.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. Tell us the hydrate form and quantity through the contact page, or tick it into the enquiry cart beside barium salts; tender purchases are described on the lab tender page.
Frequently Asked Questions
What is the difference between anhydrous and decahydrate sodium sulphate?
The anhydrous salt, Na2SO4, holds no water of crystallisation; the decahydrate, Na2SO4·10H2O, carries ten water molecules and weighs about 322.20 g/mol against 142.04. The label states which form you have.
Is sodium sulphate hazardous?
Treat it as a laboratory chemical: avoid breathing dust, prevent eye contact and ingestion, and keep work areas clean. Wear gloves, eye protection and a lab coat, and follow the Safety Data Sheet.
Who supplies the Sodium Sulphate?
Science Lab Supplies handles this salt from Ambala, India; schools, colleges and distributors receive a quotation that confirms its hydrate form, grade and pack size before anything is dispatched.
How should sodium sulphate be stored?
Keep it tightly closed in a labelled container in a dry store, away from moisture and contamination, and use clean dry tools so it does not cake or pick up other chemicals.
