Heavy water is the oxide of heavy hydrogen (deuterium) and is also called deuterium oxide. It is represented as D_(2)O . Heavy water is chemically similar to ordinary water heavy water is used for the neutron moderatory, as a trracer compound and for the preparation of deuterium. Reaction of heavy water with alkali metals liberates heavy hydrogen. heavy water can also be used for exchanging labile hydrogen with deuterium completely or partially. heavy water reacts slower than ordinary water but forms stronger bonds with other elements as compared to hydrogen. Q. Which property of heavy water is lesser in magnitude as that compared with normal water?
