Vedclass · Answer

(B) For $IA$ group hydroxides ($LiOH$ to $CsOH$),the solubility increases down the group because the lattice energy $(LE)$ decreases more rapidly than the hydration energy $(HE)$.For $IIA$ group carbonates ($BeCO_3$ to $BaCO_3$),the solubility decreases down the group because the lattice energy $(LE)$ remains relatively constant while the hydration energy $(HE)$ decreases significantly due to the increase in the size of the cation.

Among the hydroxides and carbonates of $IA$ and $IIA$ group elements respectively,on moving down the group,the correct solubility order is:
