An ionic compound is dissolved simultaneously in heavy water and soft water. Its solubility is :
A
Larger in heavy water.
B
Same in both.
C
Smaller in heavy water.
D
Smaller in simple water.
Answer
Smaller in heavy water.
Explanation
Solution
Ionic compounds are more soluble in soft water than heavy water. Soft water has high dielectric constant (78.39), while that of heavy water in 78.06. Due to higher polar character of solf water it is an excellent solvant for ionic compounds. Distillations ionic compouds takes place because of ion-dipole interactions solubility of covalent compounds is due to the formation of hydrogen bonds with water molecules.
