JEE Main Chemistry question

When ionic compounds get dissolved in water:

(A)They involve heat changes
(B)Inter-ionic attraction is reduced
(C)Ions show dipole-ion attraction with water molecules
(D)All are correctCorrect

Answer: (D)

Solution

Dissolving an ionic solid in water involves breaking the lattice (an endothermic step) and forming ion-dipole bonds with surrounding water molecules (an exothermic hydration step), giving a net heat change;
