A double salt is a salt that contains two distinct cations or two distinct anions. More specifically, the two cations (or anions) are not statistically distributed. Many examples are known. Double salts only exist in the solid state.

A double salt is a crystalline compound formed from two simple salts that crystallize together in a unique ionic lattice structure, different from either salt alone. It contains more than one type of cation or anion, as seen in alum, which includes aluminum cations and sulfate anions.
