Vedclass · Answer

(C) $1$. Thermal stability of alkali metal nitrates increases down the group as the electropositive character increases: $LiNO_3 $2$. 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: $Be(OH)_2 $3$. Thermal stability of alkaline earth metal hydroxides increases down the group as the basic character of the metal increases: $Be(OH)_2  Ca(OH)_2 > Sr(OH)_2$ is incorrect.$4$. Solubility of alkali metal carbonates increases down the group: $Li_2CO_3 < Na_2CO_3 < K_2CO_3$. This is correct.
