Concept of heavy water


Solubility of ionic conpound in heavy water is?

a) Less than ordinary water

b) Same as ordinary water

c) More than ordinary water

d) None


Dielectric constant of of a 'polar' solvent is one of the parameters that can determine how well it can make an ionic solute dissolve in it. It can also be understood as higher the dielectric constant, more effectively an ion will repel similar ions and thus will attract oppositely charged ions more.

Lower value of dielectric constant results in a less polar solvent.

Ionic conpound has been found to be less soluble in heavy water than in ordinary water. This is so because ordinary water has a higher value of dielectric constant as compared to heavy water.

Therefore, option (a) is correct.
