Ammonium thiosulfate

Description:

Ammonium thiosulfate, with the chemical formula (NH4)2S2O3 and CAS number 7783-18-8, is an inorganic compound that appears as a white crystalline solid or colorless solution. It is highly soluble in water, making it useful in various applications, including agriculture as a fertilizer and in photographic processes as a fixing agent. The compound is characterized by its ability to act as a reducing agent and is often used in analytical chemistry for titrations involving iodine. Ammonium thiosulfate is stable under normal conditions but can decompose when exposed to heat, releasing sulfur dioxide and ammonia. It is generally considered to have low toxicity, but safety precautions should still be observed when handling it, as it can cause irritation to the skin and eyes. Additionally, it plays a role in environmental chemistry, particularly in the treatment of wastewater and in the detoxification of heavy metals. Overall, ammonium thiosulfate is a versatile compound with significant industrial and agricultural relevance.
