Production and preparation of potassium sulfateApproximately 1.5 million tons were produced in 1985, usually by reactionPotassium chloride with sulfuric acid, in a process similar to the Mannheim processMannheim for the production of sodium sulfate. The process includes creating an intermediarypotassium bisulfate, an exothermic reaction that occurs atroom temperature:KCI + H2SO4 → HCI + KHSO4The second step of the process is endothermic, and requires energy input:KCI + KHSO4 → HCI + K2SO4In the laboratory, it can be prepared through the reaction of either potassium hydroxideOr potassium carbonate with sulfuric acid
