Homonym: D2O (Heavy)
D2O, also known as heavy water, is a form of water where the hydrogen atoms are replaced with deuterium, a heavier isotope of hydrogen. This gives D2O a higher molecular weight than regular water (H2O). It is commonly used in nuclear reactors and scientific research due to its unique properties, such as being a neutron moderator.
In addition to its use in nuclear applications, D2O is also utilized in various fields of chemistry and biology. It can help researchers study chemical reactions and biological processes by tracing the movement of deuterium in experiments, providing valuable insights into molecular behavior.
