We know that the salt is soluble only if hydration enthalpy more than lattice enthalpy. Then hydration occurs only when ion detaches from lattice. From where do the first ion gets energy to break bond from lattice?

This  energy is itself the Hydration Enthaply which gets released as it is always referred as negative and is exotheric reaction. And tis energy must be greater than the lattice nergy in order for solubility into the liquid.
