Which statements are correct given below?

A) Ionic compounds are less soluble in ${\mathrm{D}}_2\mathrm{O}$

B) The temperature of maximum density of${\mathrm{H}}_2\mathrm{O}$ is less than that of ${\mathrm{D}}_2\mathrm{O}$

C) ${\mathrm{K}}_{\mathrm{W}} \mathrm{of} {\mathrm{H}}_2\mathrm{O} \mathrm{is} \mathrm{morethan} {\mathrm{K}}_{\mathrm{W}} \mathrm{of} {\mathrm{D}}_2\mathrm{O}$

D) Water is also called universal solvent

E)Only Heavy water is present in Milli-Q water

Deuterium is less reactive than hydrogen due to more molecular weight than hydrogen. Deuterium molecular weight = 4 ,Hydrogen molecular weight = 2, Since water is used in almost every reaction it is called as universal solvent. But Milli-Q water is much pure water free from ions and salts, than compared to distilled water.
