Physical and Chemical Properties:
 Ammonium thiosulfate (ammonium thiosulphate in British English) is an inorganic compound with the formula [NH4]2S2O3. It is white crystalline solid with ammonia odor, readily soluble in water, slightly soluble in acetone and insoluble in ethanol and diethyl ether.

Application:

1. Ammonium thiosulfate is used in photographic fixer. It is a so-called rapid fixer, acting more quickly than sodium thiosulfate fixers. Fixation involves these chemical reactions (illustrated for silver bromide)
2. Also exploiting the stability of thiosulfate coordination complexes, ammonium thiosulfate is also used for leaching of gold and silver.
3. It works with presence of copper as a catalyst. This process is a nontoxic alternative gold cyanidation. The advantage to ammonium thiosulfate is that the pyrolysis of its silver complexes leaves a residue solely of silver sulfide, in contrast to complexes derived from sodium thiosulfate.
4. Ammonium thiosulfate can be used as a fertilizer.
5.  It can also be used as an additive to coal-waste mixtures to reduce formation of dioxins and furans during combustion.

 

Storage:

It should be stored in a cool, dry warehouse to prevent moisture and stored in ammonia-filled airtight equipment.
