It is named diamminesilver(I) dicyanidoargentate(I). The Roman numerals indicate the oxidation state of silver, which is +1. The name also reflects the ligands present in the complex cations.

The name is tris(ethane-1,2–diamine)cobalt(III) sulphate. The oxidation state of cobalt is deduced from the charge on the complex cation, which is +3, as three sulphates are needed to balance two complex cations.

It is named as triamminetriaquachromium(III) chloride. The ligands are arranged alphabetically, and the oxidation number of chromium is calculated from the charge on the complex ion, which is +3 due to the three chloride ions.

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.

Double salts, like carnallite or potash alum, dissociate completely into simple ions when dissolved. In contrast, complex ions, such as [Fe(CN)₆]⁴⁻ in K₄[Fe(CN)₆], do not dissociate into individual ions.
