Compare water and heavy water.

Heavy water is

The physical constant which is less for water than for heavy water is

Write a note on heavy water.

Normal water is mainly protium oxide, H_(2)O However, if protium atoms in normal water molecule are replaced completely by deuterium atoms, the resulting water is called heavy water. The ionization constant of protum water (H_(2)O hArr H^(+)+OH) is 1xx10^(-14) and that in heavy water (D_(2)O hArr OD^(-)) is 3xx10^(-15) is 3xx10^(-15) H_(2)O dissociates about

Some statements about heavy water are given below. (i) Heavy water is used as a moderator in nuclear reactors (ii) Heavy water is more associated than ordinary water. (iii) Heavy water is more effective solvent than ordinary water Which of the above statements are correct ?
