  • Solubility of Calcium Carbonate

    Solubility of Calcium Carbonate

    Solubility of Calcium Carbonate The solubility of salts of weak acids is very pH dependent The most important example of the pH dependence of solubility is for CaCO 3 which is the major component of sea shells limestone and marble The pH dependence of the solubility can be explained because when CaCO 3 dissolves CaCO 3s → ← Ca 2 CO
