Applications
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.

Solubility
Soluble in water, slightly soluble in acetone. Insoluble in ethanol and diethyl ether.

Notes
Hygroscopic. Incompatible with strong oxidizing agents, acids, magnesium and aluminum.
