Vedclass · Answer

(D) Carbonates of alkaline earth metals are sparingly soluble in water,whereas bicarbonates are generally soluble.Among the given compounds,$CaCO_3$ is a carbonate of an alkaline earth metal and is very poorly soluble.For alkali metal bicarbonates,solubility increases down the group as the lattice energy decreases more rapidly than the hydration energy.Therefore,the solubility order is $CaCO_3 < NaHCO_3 < KHCO_3$.

Which of the following is the correct arrangement in increasing order of solubility?
