Linear Formula: KHSO3 or HKO3S

Potassium bisulfite (or potassium hydrogen sulfite) is a chemical mixture with the approximate chemical formula KHSO3.
Potassium bisulfite in fact is not a real compound, but a mixture of salts that dissolve in water to give solutions composed of potassium ions and bisulfite ions.
Potassium bisulfite is a white solid with an odor of sulfur dioxide.
Attempts to crystallize potassium bisulfite yield potassium metabisulfite, K2S2O5.
