D2O, deuterium oxide, water containing the
isotope deuterium instead of hydrogen
(relative molecular mass 20 as opposed to 18
for ordinary water). Its chemical properties
are identical with those of ordinary water,
while its physical properties differ
slightly. It occurs in ordinary water in the
ratio of about one part by weight of
deuterium to 5,000 parts by weight of
hydrogen and can be concentrated by
electrolysis, the ordinary water being more
readily decomposed by this means than the
heavy water. It has been used in the nuclear
industry.
