Sodium Thiosulfate Powder Supplier & Distributor In India
ChemicalBull is a Sodium Thiosulfate Powder supplier, distributor, and exporter in India, supporting sourcing enquiries from water treatment companies, photographic chemical manufacturers, textile processing units, fine chemical producers, laboratories, distributors, wholesalers, and global B2B buyers.
Sodium Thiosulfate, also spelled Sodium Thiosulphate, is an inorganic salt used as a reducing agent, dechlorinating chemical, photographic fixing ingredient, and analytical reagent. Buyers should specify the required hydrate form because anhydrous Sodium Thiosulfate and Sodium Thiosulfate Pentahydrate have different CAS numbers and molecular weights.

Overview of Sodium Thiosulfate Powder
Anhydrous Sodium Thiosulfate has CAS number 7772-98-7, molecular formula Na2S2O3, and a molecular weight of approximately 158.11 g/mol. Sodium Thiosulfate Pentahydrate has CAS number 10102-17-7, formula Na2S2O3·5H2O, and a molecular weight of approximately 248.18 g/mol.
Sodium Thiosulfate is supplied in solid forms such as powder or crystals, depending on the grade. It is used to prepare aqueous reagent and process solutions. Hydrate form and assay basis affect the amount required for a specified thiosulfate concentration.
Buyers should confirm identity, hydrate form, assay method, moisture or loss-on-drying limits, insoluble matter, impurity specifications, particle form, packaging, and storage conditions before bulk procurement.
Applications of Sodium Thiosulfate Powder
Water Treatment & Dechlorination
Sodium Thiosulfate is used to reduce residual chlorine in suitable water and wastewater treatment processes. Treatment teams should establish dosage and verify the remaining chlorine concentration according to process requirements.
Photographic Processing
Sodium Thiosulfate is used in photographic fixing chemistry to help remove unexposed silver halides. Buyers should confirm the grade and compatibility with the intended photographic formulation.
Analytical & Laboratory Applications
Laboratories use Sodium Thiosulfate in iodometric titrations and related volumetric analysis. Applications include determining oxidising substances and measuring chlorine content in water or bleaching materials.
Chemical Synthesis
Sodium Thiosulfate serves as a reducing agent and sulfur source in selected synthesis routes. Documented applications include preparing Bunte salts and other sulfur-containing intermediates.
