Enthalpies of solution and hydration
What this topic asks you to be able to do
- define the term enthalpy change as it applies to hydration, ΔHhyd, and to solution, ΔHsol, and use it
- construct an energy cycle that connects lattice energy with the enthalpy changes of solution and of hydration, and use it
- carry out calculations based on each energy cycle described in 23.2.2
- explain, in qualitative terms, how an ion's charge and radius affect the numerical size of its enthalpy change of hydration
