Vedclass · Answer

(D) The solubility of alkali metal bicarbonates increases down the group due to the increase in the size of the cation,which decreases the lattice energy more significantly than the hydration energy.$CaCO_3$ (Calcium carbonate) is practically insoluble in water.Among the bicarbonates,$NaHCO_3$ is less soluble than $KHCO_3$ because the smaller $Na^+$ ion has a higher hydration energy but also a higher lattice energy compared to $K^+$.Therefore,the correct order of increasing solubility is $CaCO_3 < NaHCO_3 < KHCO_3$.
