About Sodium Thiosulfate, Anhydrous, ACS Grade

Sodium Thiosulfate, also known as Disodium Sulfurothioate, Sodium Hyposulfite, Disodium Sulfurothioate, Disodium Thiosulfate, and Sodium Thiosulphate, has the chemical formula Na2S2O3. Its anhydrous form appears as colorless to white hygroscopic crystals or crystalline powder with no odor. It is sparingly soluble in Water and insoluble in Alcohol at ambient conditions. When heated to around 300 o C, it undergoes decomposition emitting highly toxic fumes of Disodium Oxide and Sulfur Oxides. Commercially, it is produced by reacting by-product liquid of Sodium Sulfide synthesis with Sulfur Dioxide.

An ACS Grade reagent is a chemical that meets the purity requirements of the American Chemical Society. For dependable, consistent, and repeatable findings, ACS Grade reagents can be utilized in high-quality research labs.
