Heavy water, or deuterium oxide (D2O), is a variant of water with deuterium atoms, making it denser and altering its boiling and melting points. It's crucial in nuclear reactors as a neutron moderator and is used in spectroscopy, metabolic studies, and cancer therapy. Produced through methods like the Girdler sulfide process, heavy water's role in scientific advancement is significant.

Heavy water is a form of water where the two hydrogen atoms are isotopes known as deuterium, each containing one proton and one neutron
Differences in Density, Boiling Point, and Melting Point
Heavy water is about 11% denser than regular water, has a higher boiling point of 101.4 degrees Celsius, and a higher melting point of 3.82 degrees Celsius
Chemical Reactivity and Optical Transparency
Heavy water has a lower ionization constant, making it less reactive, and is optically transparent without the slight blue tint of regular water
Exposure to high concentrations of heavy water can disrupt cellular processes and prove toxic, but the body can metabolize small amounts without harm
Heavy water is present in all water sources at a concentration of about 150 parts per million
Methods of Production
Heavy water is produced through methods such as fractional distillation, electrolysis, and chemical exchange processes
The Girdler Sulfide Process
The Girdler sulfide process is the most widely used method for producing heavy water, utilizing the different chemical affinities of isotopes to separate them
Heavy water is available in various grades of purity and is used in the nuclear industry, scientific research, and medical treatments
Heavy water is used as a neutron moderator in certain types of reactors, allowing them to operate with natural, unenriched uranium
Nuclear Magnetic Resonance (NMR)
Heavy water is essential in NMR, helping to avoid interference with the signals of hydrogen-1 atoms
Study of Metabolic Processes
Heavy water is used in the doubly labeled water method to study metabolic processes
Neutron Capture Therapy for Cancer
Heavy water is used in medical treatments such as neutron capture therapy for cancer

Composition of heavy water
Heavy water consists of two deuterium atoms, each with one proton and one neutron, replacing the hydrogen in H2O.
01
Boiling and melting points of heavy water
Heavy water has higher boiling and melting points than regular water due to the presence of deuterium.
02
Viscosity comparison of heavy water to regular water
Heavy water is more viscous than ordinary water, a result of deuterium's influence on its physical properties.
