Definition of heavy water
WebApr 22, 2024 · Wikipedia has a straight-forward definition of heavy water: “Heavy water (deuterium oxide, H 2 O, D 2 O) is a form of water that contains only deuterium (2 H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope (1 H or H, also called protium) that makes up most of the hydrogen in normal water. WebThe physical properties of heavy water consist of: At standard temperature and pressure, heavy water appears to be colorless. It occurs as an odorless liquid at normal temperature. An ice cube produced of deuterium oxide will sink in regular water because its density is approximately 11% higher than H2O.
