Portaal Chemie

Ammoniumsulfaat is 'n sout van die basis ammoniak met swaelsuur. Dit het die chemiese formule (NH₄)₂SO₄.

Ammoniumsulfaat kom natuurlik voor as die seldsame mineraal mascagniet in vulkaniese fumarole of as gevolg van steenkoolbrande op sommige stortingsterreine. 'n Fumarool (of rookgat) is 'n opening in die aardkors en word dikwels in gebiede rondom vulkane aangetref, waar stoom en gasse soos bv. koolstofdioksied, swaeldioksied en waterstofsulfied vrygestel word.^[4]
