Which outcome will ensue when significant hydration occurs around crystalline NaCl?

A)Increased ion mobility in aqueous solution
B)Decreased lattice energy of solid phase
C)Elevated melting point of the crystal
D)Reduced electron affinity of chlorine ions

💡 Explanation

Increased ion mobility results from hydration shells disrupting ion pairing. Because the hydration process breaks the ionic bonds via solvation, ion separation increases ion mobility in water, rather than decreasing the lattice energy, which is a characteristic of the solid.
