Why does the solubility of alkaline earth metal hydroxide in water increase down the group?

Text Solution

Verified by Experts

If the cation and anion are of comparable size , the anion being common , the radius of cation will influence the lattice enthalpy . In the group , both the lattice enthalpy and hydration enthalpy decrease with increase in size of the cation . But the decrease in lattice enthalpy is much more than the hydration enthalpy wiht increasing ionic size and hence , solubility will increase as we go down the group . Therefore, the solubility of alkaline earth metal hydroxide increases down the group .
