More than 1 million tons were produced in 1985 as the initial stage in the Mannheim process for producing potassium sulfate. The relevant conversion is the exothermic reaction of potassium chloride and sulfuric acid:[1][2]
Mercallite, the mineralogical form of potassium bisulfate, occurs very rarely.[7] Misenite is another more complex form of potassium bisulfate with the formula K8H6(SO4)7.
