Question

diffrence between heavy and ordinary water​

Answer 1

Instead of normal protium atoms, heavy water consists of two deuterium atoms. Like normal water, heavy water is an odorless liquid at room temperature. Moreover, deuterium, tantamount to protium, is also a stable isotope.

Answer 2

Answer:

Heavy water is mainly used in nuclear reactors. Heavy water is used to slow down the neutrons that are released due to fission in the reactors. While water is essential for all, heavy water can be harmful to living organisms.....

ordinary water (the "ordinary water" used for a deuterium standard) contains only about 156 deuterium atoms per million hydrogen atoms, meaning that 0.0156% of the hydrogen atoms are of the heavy type. ... Heavy water was first produced in 1932, a few months after the discovery of deuterium.
