text: Because the concentration of CaCO 3 produced in suspension was higher than that in 1 g-F, a continuous supply of CO 2 to the suspension led to continuous dissolution of CaCO 3 according to its constant solubility product, resulting in a quasi-equilibrium, in which the EC was steadily increased and the pH was very slowly decreased.
