Examples of double salts include carnallite (KCl.MgCl₂.6H₂O), Mohr’s salt (FeSO₄.(NH₄)₂SO₄.6H₂O), and potash alum (KAl(SO₄)₂.12H₂O), formed by combining two or more stable compounds in specific stoichiometric ratios.

Examples of double salts include carnallite (KCl.MgCl₂.6H₂O), Mohr’s salt (FeSO₄.(NH₄)₂SO₄.6H₂O), and potash alum (KAl(SO₄)₂.12H₂O), formed by combining two or more stable compounds in specific stoichiometric ratios.
Examples of double salts include:
Carnallite: KCl⋅MgCl₂⋅6H₂O – A hydrated double salt containing potassium chloride and magnesium chloride.
Mohr’s Salt: FeSO₄⋅(NH₄)₂SO₄⋅6H₂O – A double salt comprising ferrous sulfate and ammonium sulfate.
Potash Alum: KAl(SO₄)₂⋅12H₂O – This hydrated double salt consists of potassium sulfate and aluminum sulfate.
These double salts exhibit a stoichiometric ratio of different ions, providing unique crystalline structures. Their behavior in water involves complete dissociation into individual ions, distinguishing them from coordination complexes where ligands remain intact upon dissolution.
