Standard Enthalpy of Ion Cu²⁺ Formation in Aqueous Solution

The enthalpies of reaction of Zn_{(c., excess)} with 0.001963 mole/kg aqueous solution of CuCl_2(c) in water at different concentrations were measured in an isothermic-shell calorimeter. According to the results and literature data obtained standard enthalpy of ion Cu²⁺ formation in aqueous solution was determined by two independent methods at 298.15 K. Its recommended weighted average was also found
