So the enthalpy of solution can either be endothermic, exothermic or neither ΔHsolution = 0 ), depending on how much heat is required or release in each step. If ΔHsolution = 0, then the solution is called an ideal solution and if ΔHsolution > 0 or ΔHsolution < 0, then these solutions are called non-ideal …
