Assertion : As a salt such as ($\mathrm{NaCl}$) dissolves, the ($\mathrm{Na}^{+}$)and ($\mathrm{Cl}^{-}$)ions leaving the crystal lattice acquire far greater freedom. Reason : In thermodyanamic terms, the formation of solution occurs with a favourable change in free energy, i.e., ($\Delta$H) has a high positive value and (T $\Delta$S) a low negative value.
