Identify the correct statements regarding the properties of s-block carbonates. — s Block Elements Chemistry Question

💡 Solution & Explanation

Solubility of Group 2 carbonates decreases down the group because hydration energy drops faster than lattice energy. They dissolve in water containing $CO_2$ to form soluble bicarbonates ($M(HCO_3)_2$). Statement B is false as $Li_2CO_3$ is less stable. Statement D is false because Group 1 carbonates (except Li) do not decompose on heating; they simply melt.
