The most important alums are potassium aluminum sulfate, ammonium aluminum sulfate, and sodium aluminum sulfate. Potassium aluminum sulfate, also known as potassium alum or potash alum, has a molecular formula of K2(SO4) Al2(SO4) 24H2O or KAl(SO4)
- 12H2O. However, any of the compounds with the empirical formula AB(SO4) 12H2O are considered to be an alum
