$Li_2CO_3 < Na_2CO_3 < K_2CO_3 < Rb_2CO_3$ (Thermal stability)

Vedclass · Answer

(C) $1$. Thermal stability of alkaline earth metal carbonates increases down the group as the electropositive character increases: $BeCO_3 $2$. Solubility of alkaline earth metal sulfates decreases down the group due to the decrease in hydration energy: $BeSO_4 > MgSO_4 > CaSO_4 > SrSO_4$. Thus,option $B$ is correct.$3$. Thermal stability of alkali metal carbonates increases down the group: $Li_2CO_3  Na_2CO_3 > K_2CO_3 > Rb_2CO_3)$ is incorrect.$4$. Solubility of carbonates of alkaline earth metals decreases down the group: $BeCO_3 > MgCO_3 > CaCO_3 > SrCO_3$. Thus,option $D$ is correct.
