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.

NaCl is more soluble in ordinary water than in heavy water,Due to dielectric constant(D) of H2O is greater than that of D2OD : H2O > D2OSolubility: H2O > D2ODielectric constant[D]: Dielectric constant is the measure of a solvent to ionise the saltDielectric constant easy of ionisationStatement I and Statement II are true.
