Abstract
The temperature dependence of the solubility product of copper (II) oxalate CuC2O4 was determined in the range 20–45 °C from the results of precipitation potentiometric titration of aqueous Cu2+ solution with oxalate solution. The titration was performed with a copper indicator electrode. Based on the obtained values of the solubility product, the formation enthalpy and entropy of solid copper oxalate have been found.
