What is the difference between heavy water and water

Heavy water. It looks very similar to ordinary water, it is an odorless and tasteless liquid, and their chemical properties are the same, but some physical properties are different. The density of ordinary water is 1 gram cm3, while the density of heavy water is gram cm3; The boiling point of ordinary water is 100, and the boiling point of heavy water is; The freezing point of ordinary water is 0, and the freezing point of heavy water is .

In addition, ordinary water nourishes life and nurtures all things, while heavy water does not make seeds germinate. Drinking heavy water can also cause death for humans and animals. However, the special value of heavy water is reflected in the application of atomic energy.

Build a powerful nucleus**.

Heavy water is needed as a moderator in the nuclear fission reaction, as a moderator for neutrons, and can also be used as a material for heavy hydrogen production, and the content in ordinary water is about the mass fraction). Heavy water, like ordinary water, is a liquid compound made from hydrogen and oxidation, however, heavy water molecules.

It is different from the hydrogen atom of a normal water molecule. We know that there are 3 isotopes of hydrogen.

One is the Aga, which contains only one proton. It is combined with an oxygen atom to produce ordinary water molecules. The other is heavy hydrogen – deuterium.

It contains one proton and one neutron. It is combined with an oxygen atom to form heavy water molecules. There is also tritium ——— tritium.

It contains two neutrons and one proton.

and dissolved substances (elementals, minerals, gases. The national standard divides the water quality into five categories (presumably, it is impossible to say more specifically) to achieve.

Category 1 and 2 (as if they were) are directly potable water, i.e., "high-quality water sources". Hazardous substances (arsenic, lead, mercury and other heavy metals, toxic substances. The content must be below a certain value.

Mineral water and mineral water are: water containing certain mineral dissolved substances, in which trace elements are necessary for the human body, but the content can not be too high, and it can only be drunk if it meets the national standards. Heavy water is fundamentally different from ordinary water:

An ordinary water molecule is made up of two hydrogen atoms and one oxygen atom. The heavy water molecule is made up of two isotopes of hydrogen – deuterium or tritium (pronounced chuan) and an oxygen atom. Heavy water is essential in the nuclear industry and is found in very little in nature.

In order to get it, people take advantage of the performance that heavy water cannot be electrolyzed, and at any cost, a large amount of seawater is electrolyzed, and the rest that cannot be electrolyzed is "heavy water". If the water quality in your hometown is not good (prone to stone disease), it is estimated that the water quality is too "hard" – that is, it contains more mineral dissolutes. The easiest way to dispose of this "hard water" (not heavy water) is to boil it and drink it (it removes most of the calcium carbonate).

If you have the financial means, you can buy water treatment equipment in the mall, and after treatment, the water quality can be greatly improved.

What is heavy water? What is the difference between water and water? Just freeze the heavy water into ice cubes and put it in the water.
