About Sodium Thiosulfate, Anhydrous, Lab 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. Chemically pure or Laboratory reagents are the
two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any
accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC
Grade, despite their acceptable purity. In the United States of America (USA), Lab Alley is selling
its high-quality Sodium Thiosulfate, Anhydrous, Lab Grade online at laballey.com. Due to its high
purity, this Lab Alley product is highly recommended for labs and commercial applications.
