$LiHCO_3 < NaHCO_3 < KHCO_3$

Vedclass · Answer

(A) The solubility of alkali metal bicarbonates increases down the group due to the decrease in lattice energy being more significant than the decrease in hydration energy. Thus,the order is $LiHCO_3 For alkaline earth metal sulfates,solubility decreases down the group as hydration energy decreases more rapidly than lattice energy,so $MgSO_4 > CaSO_4 > BaSO_4$. For alkali metal chlorides,solubility increases down the group as $NaCl For alkaline earth metal hydroxides,solubility increases down the group as $Be(OH)_2 Therefore,the correct order is $LiHCO_3 < NaHCO_3 < KHCO_3$.
