Description and Uses
Ammonium thiosulfate is a white crystallinesolid with an ammonia odor. Molecular weight= 148.21;Freezing/Melting point= 150 C [decomposes ,50℃(solution); .100℃ (anhydrous crystals)]. HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 0, Reactivity 0. Highly soluble inwater.
Ammonium thiosulfate finds application for leaching of gold and silver since it forms strong complexes. It is widely utilized as a photographic fixing agent, which acts quicklier than sodium thiosulfate fixers. It serves as a fertilizer. It acts as an additive to coal-waste mixtures to inhibit the formation of dangerous dioxins and furans. It is used as an analytical reagent in laboratories.
