Question

Low solubility of CsI in water is due to :

Options

A.smaller hydration enthalpy of Cs+.
B.smaller hydration enthalpy of I–.
C.lower lattice enthalpy of its two ions.
D.(A) and (B) both.

Solution

True statement. The CsI, because of bigger cation (Cs+) and bigger anion (I-), has smaller hydration enthalpy. As a result, it does not exceed its lattice energy ; so CsI is insoluble in water.
