Heavy water is less dissociated than light water at given temperature, and the true concentration of D + ions is less than H + ions would be for light water at the same temperature. The same is true of OD − vs. OH − ions. For heavy water Kw D 2 O (25.0 °C) = 1.35 × 10 −15, and [D + ] must equal [OD − ] for neutral water
99.8% pure compressed deuterium gas, in lot size of 850 L (142 g). Also sold by same supplier in the form of heavy water at price of 3940 USD per kg deuterium. [12] In 2016, Iran sold 32 tons of heavy water to United States for 1336 USD per kg deuterium. [13] 2: He: Helium: 0.0001785: 0.008 (2.216 × 10 14 kg) 24.0: 0.004 29: 2018: USGS MCS [14]

Water portal; Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium atoms. In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [1] and it is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H 2 O plus ...
Baby food labels will disclose levels of lead and other toxic heavy metals via QR codes, thanks to a California law taking effect January 1.
The heavy water project was codenamed the "P-9 Project" in October 1942. [6] The problem with using heavy water was that it was scarce, and scientists could not readily acquire the quantities required by a reactor. At Columbia University in the United States, Enrico Fermi and Leó Szilárd attempted to use graphite as a moderator instead.

A heavy liquid is a solution or liquid chemical substance with a high density and a relatively low viscosity. Heavy liquids are often used for determination of density in mineralogy, for density gradient centrifugation and for separating mixtures .
