|Section2= |Section4= |Section7= |Section8= }} Potassium bisulfate is a potassium acid salt of sulfuric acid, with the molecular formula . This compound is commonly used in the conversion of tartrates to bitartrates in wine. Potassium bisulfate is also used as a disintegrating agent in analytical chemistry. A solution of potassium bisulfate behaves as if the two related compounds ( and ) were side by side uncombined. Adding ethanol to a solution of potassium bisulfate precipitates out sulfate. Mercallite, the mineralogical form of potassium bisulfate, occurs very rarely. Misenite is the other, more complex, potassium hydrogen sulfate. ==Preparation== Potassium bisulfate is prepared by the reaction between sulfuric acid and potassium carbonate. Carbon dioxide gas is produced as a by-product. Potassium bisulfate is also the main by-product of the production of nitric acid by the distillation of potassium nitrate and sulfuric acid. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「potassium bisulfate」の詳細全文を読む スポンサード リンク
