Determine the standard enthalpy change of the precipitation reaction between aqueous solutions of copper (II) sulfate and calcium hydroxide, given that the reaction produces copper (II) hydroxide, solid calcium sulfate and water as the products. The initial concentrations of the solutions are 0.1 M for copper (II) sulfate and 0.05 M for calcium hydroxide, and the reaction takes place at constant pressure and temperature of 25°C.
