Potassium thiosulfate

Description:

Potassium thiosulfate, with the chemical formula K2S2O3 and CAS number 10294-66-3, is an inorganic compound that appears as a white crystalline solid, often found in the form of a pentahydrate. It is soluble in water, forming a clear solution, and is known for its mild alkaline properties. This compound is primarily used in various applications, including photography as a fixer, in agriculture as a fertilizer and fungicide, and in analytical chemistry as a reducing agent. Potassium thiosulfate is also utilized in water treatment processes to dechlorinate water and in the food industry as a preservative. Its stability is generally good under normal conditions, but it can decompose upon prolonged exposure to heat or light, releasing sulfur dioxide and other products. Additionally, it is considered to have low toxicity, making it relatively safe for handling in laboratory and industrial settings. Overall, potassium thiosulfate is a versatile compound with significant utility across multiple fields.

Potassium thiosulfate

CAS: 10294-66-3

Potassium thiosulfate is a salt that can be used to prepare a reaction solution for the detection of hydroxyl groups, which are found in polymers and other organic compounds. The potassium thiosulfate decomposes to release sulfur dioxide with the help of calcium pantothenate, a reducing agent. The resulting colloidal gold is then mixed with the polymer composition, and the particle size is observed using a polarizer. A chemiluminescent reaction is triggered by potassium dichromate and emits light when it oxidizes. This light emission can be detected using a photomultiplier tube and an appropriate filter.
