:Thiosulfuric acid (H2S2O3), ammonium salt (1:1)
Description:
Thiosulfuric acid (H2S2O3), ammonium salt (1:1), commonly referred to as ammonium thiosulfate, is an inorganic compound characterized by its formulation as a salt derived from thiosulfuric acid and ammonium. It typically appears as a white crystalline solid or a colorless solution, exhibiting high solubility in water. This compound is known for its role in various applications, including agriculture as a fertilizer and in photographic processing as a fixing agent. It acts as a source of sulfur and can participate in redox reactions, making it useful in analytical chemistry. The ammonium salt form provides a stable and less corrosive alternative to other sulfur compounds. In terms of safety, while it is generally considered to have low toxicity, it should still be handled with care to avoid irritation to the skin and eyes. Its chemical properties allow it to act as a reducing agent, and it can decompose under certain conditions, releasing sulfur dioxide and other products.
