Question

LiCl is hydrated but NaCl is always anhydrous. If true enter 1, else enter 0.

Answer 1

$L{i}^{+}$ ion has smaller ionic radius than $N{a}^{+}$. Hence, it has larger charge density and higher polarization power. Hence, LiCl undergoes hydration but NaCl does not. Hence, LiCl is hydrated but NaCl is always anhydrous.
