The solubility of sulphates of alkaline earth metals in water...

The solubility of sulphates of alkaline earth metals in water decreases down the group because

Options

  1. AThe lattice energy of sulphates of group II decreases down the group
  2. BThe lattice energy of sulphates of group II increases down the group
  3. CBoth hydration and lattice energies decreases down the group
  4. DThe decrease in hydration energy is more than the decreases in lattice energy

Correct answer

D. The decrease in hydration energy is more than the decreases in lattice energy

Step-by-step solution

Both lattice energy and hydration energy decreases down the group of alkaline earth sulphates but hydration energy decreases more rapidly than lattice energy.
