Enthalpy change when 1 mol ionic solid dissolves in water (infinitely dilute)
Breaks down; ions surrounded by solvent molecules
ΔHsol=ΔHlattice+ΔHhydration\Delta H_{sol} = \Delta H_{lattice} + \Delta H_{hydration}ΔHsol=ΔHlattice+ΔHhydration
Energy to separate 1 mol ionic compound into gaseous ions
Endothermic
Enthalpy change when 1 mol gaseous ions dissolve in water to form hydrated ions
Exothermic (energy released when water bonds with ions)
Water is polar with partial charges on H and O atoms
Negative end (oxygen)
Positive end (hydrogen)
