Enthalpy change of solution

• L.O.
• L.O.
• Use the enthalpy change of solution of a simple
  ionic solid and relevant enthalpy change terms to
  construct BornHaber cycles.
• Carry out related calculations.

2
The standard enthalpy change of solution is the
enthalpy change that takes place when one mole
of a compound is completely dissolved in water
under standard conditions
3
Ionic lattice dissolves in polar solvents each
ion is surrounded by water molecules to become
hydrated
4
BornHaber cycle for calculating the enthalpy
change of solution of KCl(s)
5
Standard enthalpy change of hydration is the
enthalpy change that takes place when one mole of
isolated gaseous ions is dissolved in water
forming one mole of aqueous ions under standard
conditions.

change of solution of KCl(s)
