Ionic Equilibria in Alkaline Aqueous Solutions of Metal Complex Salts

摘要

A thermodynamic analysis of the formation conditions of metal hydroxides was performed.The areas of stable formation of metal hydroxide precipitates in the coordinates pH-metal concentration,including also solutions containing various kinds of complexing agents,were evaluated.With the precipitation of cadmium hydroxide as example,X-ray phase analysis confirmed the formation of metal hydroxide in the chemical composition areas where its formation is predicted by a thermodynamic analysis.
