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

Question

The solubility of sulphates of alkaline earth metals in water decreases down the group because (A) The lattice energy of sulphates of group II decreases down the group (B) The lattice energy of sulphates of group II increases down the group (C) Both hydration and lattice energies decreases down the group (D) The decrease in hydration energy is more than the decreases in lattice energy

Tardigrade Admin · Accepted Answer

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

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

The lattice energy of sulphates of group II decreases down the group

The lattice energy of sulphates of group II increases down the group

Both hydration and lattice energies decreases down the group

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

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