Lattice enthalpy
the change in enthalpy associated with the separation of the ions of 1 mole of an ionic solid thereby forming gaseous ions
Hydration enthalpy
the change in enthalpy associated with 1 mole of gaseous ions dissolving in water to form a solution
Hess’s Law
states that the difference in enthalpy between two sets of chemicals is the same regardless of how one set of chemicals is transformed into the other set of chemicals
Hydration enthalpies
related via energy cycles to enthalpy changes of solution and lattice enthalpy
Lattice enthalpies
related via energy cycles to the enthalpy changes for some or all of the following types of reaction: sublimation, melting, vaporization, ionization, covalent bond breaking, electron affinity, and formation.
