So the enthalpy of solution can either be endothermic, exothermic or neither ΔHsolution = 0 ), depending on how much heat is required or …
WebEstimating enthalpies of solution from lattice enthalpies and hydration enthalpies. The hydration enthalpies for calcium and chloride ions are given by the equations: The following cycle is for calcium chloride, and includes a lattice dissociation enthalpy of +2258 kJ mol … WebConclusion. The enthalpy of solution of CuSO4 is 16 kcal. Electrolysis is an electrochemical process in which current flows from one electrode to the next in an ionised electrolyte solution. Positive ions, or cations, are drawn to the negative electrode, or cathode, while negative ions, or anions, are drawn to the positive electrode, or anode.
