'''Ammonium bisulfate''', also known as '''ammonium hydrogen sulfate''', is a white, ]line solid with the ] (NH<sub>4</sub>)HSO<sub>4</sub>. This salt is the product of the half-neutralization of sulfuric acid by ]. |
|
|
|
|
|
==Production== |
|
|
It is commonly collected as a byproduct of the "acetone cyanohydrin route" to the commodity chemical ].<ref>William Bauer, Jr. "Methacrylic Acid and Derivatives" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. {{doi|10.1002/14356007.a16_441}}.</ref> |
|
|
|
|
|
It can also be obtained by hydrolysis of ] in aqueous solution, which produces the salt in high purity: |
|
|
:{{chem2 | H3NSO3 + H2O -> (NH4)HSO4 }} |
|
|
It also arises by the thermal decomposition of ]: |
|
|
:{{chem2 | (NH4)2SO4 -> (NH4)HSO4 + NH3 }} |
|
|
|
|
|
==Applications== |
|
|
It can be further neutralized with ammonia to form ammonium sulfate, a valuable ]. It can be used as a weaker alternative to sulfuric acid, although ] is much more common. |
|
|
|
|
|
==Natural occurrence== |
|
|
A related compound of the (NH<sub>4</sub>)<sub>3</sub>H(SO<sub>4</sub>)<sub>2</sub> formula, occurs as the rare mineral ], known from coal fire environments.<ref>{{Cite web|url=https://www.mindat.org/min-2382.html|title=Letovicite}}</ref><ref>{{Cite web|url=https://www.ima-mineralogy.org/Minlist.htm|title=List of Minerals|date=21 March 2011}}</ref> |
