The precipitations of the sparingly‐soluble acid, neutral and basic salts of the divalent cations beryllium, magnesium, calcium, strontium, barium, manganese (II), iron (II), cobalt (II), nickel (II), copper (II), zinc, cadmium, mercury (II), tin (II) and lead (II) with the inorganic anions sulphate, chromate, molybdate, monohydrogen phosphate, phosphate, and carbonate (from supersaturated aqueous solutions) are surveyed. The different types of ionic equilibria (cation hydrolysis, anion hydrolysis, ion‐pair formation) that may influence these precipitations, at different p Hs and ionic concentrations, are examined. The crystalline phases precipitated at different p Hs are tabulated and the precipitation mechanisms (at different p Hs) are analysed.
