Reference Entry
Alum, a chemical compound of two sulfates and water. (A sulfate is a compound of sulfur, oxygen, and one or more other elements.) One of the two sulfates usually contains aluminum, but it can be any other metal with a valence of 3, such as chromium or iron. The other sulfate usually contains an alkali metal, such as potassium, but can instead contain either another metal with a valence of 1 or ammonium (a group of atoms formed by combining ammonia and hydrogen). At ordinary temperatures, all alums are solids.
