Ammonium thiosulfate, chemical formula (NH4)2S2O3. Molecular weight 148.20. Colorless monoclinic crystals. Melting point 150℃(decomposition), relative density 1.679. Soluble in water, insoluble in ethanol, slightly soluble in acetone. Its aqueous solution has sulfur precipitation for a long time. Above 50℃, its concentrated aqueous solution gradually decomposes into sulfur and sulfate. Ammonium thiocyanate and ammonium sulfite are formed in the presence of ammonia and hydrocyanic acid. Aqueous solution can dissolve halide Chemicalbook silver. Its solubility for silver chloride and silver bromide is greater than sodium thiosulfate, so it is also used as a rapid fixer. But it has a dissolving effect on the silver metal that makes up the image. Preparation method: Excess ammonium carbonate can be added to calcium thiosulfate aqueous solution, or ammonium hydrogen sulfide and ammonium bisulfite aqueous solution can be mixed according to the exact molar ratio of 1:2, and then prepared by reaction; It can also be prepared by freezing crystallization of ammonium sulfite and ammonium polysulfide after sulfur removal by double decomposition reaction.
