####44. Sodium sulphate is soluble in water, whereas barium sulphate is sparingly soluble because
$(1989,1 M)$
(a) the hydration energy of sodium sulphate is more than its lattice energy
(b) the lattice energy of barium sulphate is more than its hydration energy
(c) the lattice energy has no role to play in solubility
(d) the hydration energy of sodium sulphate is less than its lattice energy
Show Answer
Answer:
Correct Answer: 44. $(a, b)$
Solution:
- Solubility of a salt is influenced by two major factors, lattice energy and hydration energy. For greater solubility, there should be smaller lattice energy and greater hydration energy.
