Water and Heavy water

Question

Statement I: NaCl is less soluble in heavy water than in ordinary water.
Statement II : Dielectric constant of ordinary water is more than that of heavy water.

Easy

A

Statement I and Statement II are true.
B

Statement I is true and statement II is false.
C

Statement I is false and Statement II is true.
D

Statement I and Statement II are false.

Solution

NaCl is more soluble in ordinary water than in heavy water,Due to dielectric constant(D) of H₂O is greater than that of D₂O
D : H₂O > D₂O
Solubility: H₂O > D₂O
Dielectric constant[D]: Dielectric constant is the measure of a solvent to ionise the salt
Dielectric constant $\propto$ easy of ionisation
Statement I and Statement II are true.
