WebRelating Hydration Energy to Lattice Enthalpy For aqueous solutions, the ΔHsolvent Δ H s o l v e n t and ΔHmix Δ H m i x terms can be combined to give the heat of hydration, ΔHhyd Δ H h y d, which allows to write the heat of solution as ΔHsoln =ΔHsolute +ΔHhydration Δ H s o l n = Δ H s o l u t e + Δ H h y d r a t i o n Web3) Standard enthalpy change of hydration, ΔH° hyd is the enthalpy change when one mole of gases ions dissolves in water to form hydrated ions of infinite dilution under standard conditions. H = ΔH° hyd 4) Standard enthalpy change of hydration is always exothermic, this is because when an ion dissolves in water, bonds are formed between
