bisulfates
Bisulfates are salts that contain the bisulfate anion, HSO4−. They occur when sulfuric acid is only partially neutralized, and are commonly encountered as alkali or ammonium salts such as sodium bisulfate (NaHSO4), potassium bisulfate (KHSO4), and ammonium bisulfate ((NH4)HSO4). They are distinct from bisulfites, which contain the HSO3− anion.
In water, bisulfate salts produce acidic solutions because the bisulfate anion can donate a proton to water,
Preparation and occurrence: Bisulfates are produced by partial neutralization of sulfuric acid or by acidifying sulfates.
Safety and handling: Bisulfates can be irritants and are corrosive in concentrated form. They should be handled
