${\mathrm{\Delta }}_{\mathrm{sol}}{\mathrm{H}}^0$ is ....(i)..... and the dissociation process is ...(ii)... in most of the ionic compounds. Identify (i) and (ii) to complete the above statement,

for an ionic compound to dissolve the electrostatic forces between oppositely charged ions must be cleaved, energy is required.

Lattice energy is higher than hydration enthalpy, enthalpy of solution is positive and endothermic process
