Question
The solubilities of carbonates decrease down the magnesium group due to a decrease in
Options
A.hydration energies of cations
B.inter-ionic attraction
C.entropy of solution formation
D.lattice energies of solids
Solution
The solubility is governed by ᐃHsolution i.e. ᐃHsolution = ᐃHlattice - ᐃHHydration
Due to increase in size the magnitude of hydration energy decresaes and hence the solubility.
