DETERMINATION OF THE REACTION HEAT AND STUDIES OF THERMODYNAMIC FUNCTIONS - HYDROLYTIC POLYMERIZATION OF CHROMIUM(III) AT RELATIVELY HIGH-CONCENTRATIONS BY MICROCALORIMETRY

The hydrolytic polymerization of Cr3+ at relatively high concentration s was studied by microcalorimetry. The thermal curves were determined with a 2277 thermal activity monitor. From the curves, the identified reaction heats (Delta rH(m)(sigma)), hydrolysis constants (K) and ther modynamic functions (Delta rG(m)(sigma),Delta rS(m)(sigma)) were calcu lated at different temperatures.
