Abstract: A uniform procedure is suggested for calculation of the pHt value(s) separating equilibrium solid phases in pH scale, at an excess of the precipitating agent. The pHt value, related to pairs of precipitates formed from the species and , fulfils the relation , where F is a constant value involving pKso’s for solubility products (Kso’s) of these precipitates, and the equilibrium data, related to the species composing these precipitates.

Keywords: Electrolytic Systems, Precipitates, pH-Intervals
