Vedclass · Answer

(D) $1$. Solubility of alkaline earth metal hydroxides increases down the group due to the decrease in lattice energy being more significant than the decrease in hydration energy. Thus,$Ca(OH)_2 $2$. Solubility of alkali metal carbonates increases down the group as hydration energy decreases less rapidly than lattice energy. Thus,$Li_2CO_3 $3$. Solubility of alkali metal bicarbonates increases down the group. Thus,$NaHCO_3 $4$. For alkaline earth metal thiosulfates,the solubility decreases as the size of the cation increases. The correct order is $CaS_2O_3 > SrS_2O_3 > BaS_2O_3$. Therefore,the given order $BaS_2O_3 < MgS_2O_3 < CaS_2O_3$ is incorrect.
