Resumen de The Teaching of Precipitation Equilibrium:: A New Approach
In this paper we present a simplified integrated approach to the calculation of the solubility in water of a salt, and the pH of the saturated solution, taking into account the acid-base reactions of the anion. A classification of the salt, based upon the values of the appropriate equilibrium constants, is done with the help of a decision tree. This classification is used as a guide for the identification of the assumptions that have to be made to obtain a set of easily resolvable equations. The application of the method is discussed with examples.
