An introduction to Sodium thiosulfate

Posted in General | 09:38

Sodium thiosulfate is a colorless, crystalline solid with a melting point of 48 degrees C. It is freely soluble in water. In analytical chemistry, sodium thiosulfate is used for the determination of the strength of a given solution of iodine. Sodium thiosulfate is preferred in iodometric analysis due to the fact that sodium thiosulfate is oxidized by iodine. It is also used to determine the strength of many oxidizing agents, such potassium dichromate, potassium permanganate and copper sulfate, which, on reacting with excess KI (potassium iodide) solution, liberate iodine. The liberated iodine is titrated with a standard solution of sodium thiosulfate. Established in 1954, Kaixiang Chemical Factory specializes in producing Sodium Bicarbonate, sodium metabisulphite.
