Why solubility of alkaline earth metal compounds are comparatively less than the corresponding alkali metal compounds in water?
The solubility of alkaline earth metal compounds are comparatively less than the corresponding alkali metal due to the small size of bivalent ions of alkaline earth metals, the lattice enthalpy of alkaline earth metal compound is very high as compared to those of the metals of the first group.
