Identify the correct statements regarding the sulphates of Group 1 and Group 2 elements. — s Block Elements Chemistry Question

💡 Solution & Explanation

$BaSO_4$ is highly insoluble in water because its hydration energy is much lower than its lattice energy. Alkali metal sulphates (except Lithium) form alums (e.g., $K_2SO_4 \cdot Al_2(SO_4)_3 \cdot 24H_2O$). Thermal stability of Group 2 sulphates increases down the group due to decreasing cation polarizing power. $MgSO_4$ forms Epsom salt ($MgSO_4 \cdot 7H_2O$).
