Question
Sodium sulphate is soluble in water whereas barium sulphate is sparingly soluble because
Options
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
Solution
If Eh > EL substance will be soluble in water.
If Eh < EL substance will be insoluble in water.
Because Na2SO4 is water soluble so for it Eh > EL
Because Ba2SO4 is water insoluble so for it Eh < EL
If Eh < EL substance will be insoluble in water.
Because Na2SO4 is water soluble so for it Eh > EL
Because Ba2SO4 is water insoluble so for it Eh < EL
