Equilibrium of the solubility isotherm in systems Cobalt(II) chloride-glutamic acid-water

Abstract

The study is focused on the interaction between glutamic acid and hexavodic cobalt chloride. The solubility curve, influenced by the high solubility of the initial components, extends horizontally along a catheter corresponding to the cobalt chloride content. The secretion of glutamic acid exhibits a gradual increase over a relatively extended period. As the cobalt chloride concentration in the solution reaches 25.04%, a new phase emerges, resulting from the molecular interaction of the reactants, forming a double dihydrous compound comprising one molecule of glutamic acid and cobalt chloride: C5H9NO4∙CoCl2.
