The dissolution reaction of MgCl2 (s) can be written as
=> MgCl2 (s) ----------> Mg2+ (aq) + 2 Cl- (aq)
The enthalpy of any solution is given by
=> ΔHsol = ΔHlat + ΔHhydr of all ions
where ΔHsol = Enthalpy of solution
ΔHlat = Lattice energy of compound
And ΔHhydr of all ions = enthalpy of hydration of all ions
