Question
Sodium sulphate is soluble in water but barium sulphate is sparingly soluble because :
Options
A.the hydration energy of Na2SO4 is more than its lattice energy
B.the lattice energy of BaSO4 is more than its hydration energy
C.the lattice energy has no role to play in solubility
D.the lattice energy of Na2SO4 is more than its hydration energy
Solution
A compound is soluble in water when it′s hydration energy is greater than that of lattice energy.
(A) The hydration energy of Na2SO4 is more than its lattice energy; so it is soluble in water.
(B) The lattice energy of BaSO4 is more than its hydration energy; so it is insoluble in water.
(A) The hydration energy of Na2SO4 is more than its lattice energy; so it is soluble in water.
(B) The lattice energy of BaSO4 is more than its hydration energy; so it is insoluble in water.
