The net enthalpy change occurring during dissolution of 1 mol of solid (∆solH) is given by the expression
∆solH = ∆LH + ∆HydH)
  ∆LH and ∆HydH are Lattice energy, and hydration energy, respectively.
  • If ∆Hyd ∆LH; Dissolution occurs with ∆Hyd
  • If ∆Hyd marginally less than ∆LH even then dissolution takes place ∆Hyd>0.
  • If ∆LH is too large to be compensating by ∆Hyd then dissolution doesn’t takes place.

Gibbs free enrgy negative for  spontaneous process.
 and temperatue and entropy are having the significat effect on free enrgy values.
