Enthalpy change when 1 mol ionic compound separates to gaseous ions
Enthalpy change when 1 mol gaseous ions dissolve & hydrate in water
Less negative (weaker attraction, ions further apart)
More negative (stronger electrostatic attraction)
Less negative (lower charge density, weaker attraction)
More negative (stronger ion-dipole interactions)
More negative lattice enthalpy → higher melting point
Lower (charge spread over greater volume)
When total hydration enthalpy > lattice enthalpy (in magnitude)
Explains why some endothermic dissolutions still occur
