How is heavy water prepared? Compare its physical properties with those of ordinary water.

Answer:

Heavy water, which is composed primarily of deuterium oxide (D2O), is produced primarily by the electrolysis of regular water.

1. Ordinary water has a molecular mass of 18.015 while heavy water has a molecular mass of 20.027.

2. The melting point of regular water is 273.0 degrees Celsius, while the melting point of heavy water is 276.8 degrees Celsius.

3. The boiling point of regular water is 373.0 degrees Celsius, while the boiling point of heavy water is 374.4 degrees Celsius.

4. The density of regular water at 298K is 1.000, while the density of heavy water is 1.106.
