Vedclass · Answer

(B) The solubility of ionic compounds in water depends on the balance between lattice energy and hydration energy.For alkali metal salts with small anions (like $F^-$),lattice energy dominates,and solubility increases as the cation size decreases $(LiF > NaF > KF)$.For salts with large anions (like $HCO_3^-$,$CO_3^{2-}$,$NO_3^-$),hydration energy dominates,and solubility increases as the cation size increases.Therefore,for bicarbonates $(HCO_3^-)$,the solubility order is $NaHCO_3 Thus,option $B$ is the correct order.

The correct order of increasing solubility in water is
