1
Lattice Enthalpy
Enthalpy change that accompanies the formation of one mole of an ionic compound from its gaseous ions under standard conditions.
2
What does Lattice Enthalpy involve?
It involves bond formation from separate gaseous ions. It is an exothermic change (value will be negative).
3
Solid ionic compounds
-Stable which arises from the strength of ionic bonds, electrostatic attractions between oppositely charged ions in the ionic in the ionic lattice structure
-This creates a substantial energy barrier that must be overcome to break down the lattice which is reflected by high melting points
-Lattice enthalpy is the measure of the strength of ionic bonding in a giant lattice.
