When water is electrolyzed—i.e., decomposed by an electric current (actually a water solution of an electrolyte, usually sodium hydroxide, is used)—the hydrogen gas produced contains a smaller fraction of deuterium than the remaining water, and, hence, deuterium is concentrated in the water. Do you expect this makes it radioactive or not? Heavy water (deuterium oxide, H 2O, D 2O) is a form of water that contains only deuterium ( H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope ( H or H, also called protium) that makes up most of the hydrogen in normal water. Heavy water is prepared either by prolonged electrolysis or by fractional distillation of ordinary water. The substance we call heavy water is H 2 O in which many of the hydrogen atoms are replaced by deuterium. Bonus Fact 1: If you did drink too much heavy water, even though heavy water is not radioactive, your symptoms would mimic radiation poisoning. Ordinary water is heavy to carry and is the density reference point (density 1). Also called deuterium oxide. Heavy Water Definition. 1K likes.
