Question

What are the properties of normal water compared to heavy water?

Answer 1

Definition

Heavy Water: Heavy water is a form of water that contains D2O molecules.

Normal Water: Normal water is the most abundant form of water which is composed of H2O molecules.

Molecules

Heavy Water:  Heavy water is composed of D2O molecules.

Normal Water:  Normal water is composed of H2O molecules.

Molar Mass

Heavy Water: The molar mass of heavy water is about 20 g/mol.

Normal Water:  The molar mass of normal water is about 18 g/mol.

Boiling Point

Heavy Water:  The boiling point of heavy water is about 101.4oC.

Normal Water: The boiling point of normal water is 100oC.

Density

Heavy Water: The density of heavy water is comparatively high.

Normal Water:  The density of normal water is comparatively less.

Ice

Heavy Water:  The ice cubes formed from heavy water will sink in liquid water due to high density.

Normal Water: The ice cubes formed from normal water will float on liquid water due to its low density.
