Question

write two methods of preparation of D2o and also write physical and chemical properties and uses of it

Answer 1

Heavy water or deuterium oxide (D2O) is a form of water that contains a large amount of the hydrogen isotope deuterium which is also known as heavy hydrogen. Deuterium differs from the hydrogen which is usually found in water. Heavy water may be deuterium protium oxide (DHO) or deuterium oxide (D2O).

The increase in mass due to the presence of deuterium gives it a different chemical and physical property compared to normal water.

Some other heavy forms of water are:

Tritiated water

Heavy-oxygen water

Semiheavy water
