Sažetak
A numerical method for following the precipitation of slightly soluble salts of polyprotic weak acids is developed. Numerical results agree reasonably with measured data. A quantitative method of following the precipitation of slightly soluble salts of polyprotic weak acids is described ; the method is based on a computer program designed to simulate the precipitation at constant pH. The program simulates the simultaneous formatioi of a number of precipitates of different composition which can be slightly soluble salts of the weak polyprotic acid HnA (n ⩽ 5) and/or hydroxides of the metallic cations of groups I, II and III of the periodic table, provided that the molar ratio of the ions involved is constant during precipitation and that hydrogen or hydroxyl ions are liberated in the process. The program takes into account the probability of the formation of soluble complexes of the type BHn — iA as well as metal hydroxo complexes.
