Difference between Water and Heavy Water

Water vs. Heavy Water

If you want to learn the difference between water and heavy water, then you have landed at the right place. Below this post is all about the difference between water and heavy water.

Difference between Water and Heavy water

Water

Water is a chemical compound essential for almost all life forms. It is interesting to know that a single drop of water contains billions of molecules. The water molecule is formed from the combination of two hydrogen atoms and one oxygen atom (H2O). In its pure form it is colorless, odorless and has no taste.

It is a unique substance and can be found naturally in the three states in which matter can be: solid, liquid and gaseous. It is known as the “universal solvent”. Boil at 100 ° Celsius and freeze at 0 ° Celsius.

Heavy water

Heavy water (deuterium oxide) is also water, but contains two atoms of the deuterium isotope. It differs from normal water in terms of its density. The heavy water is 11% more dense than ordinary water.

Like water, heavy water also occurs naturally. However, it is not as common as normal water. Due to the isotopic substitution with deuterium, the binding energy of H and D of the water is affected. This is the detail responsible for causing changes in various physical and chemical properties of heavy water.

Key Difference between Water and Heavy Water

  • Normal water is composed of two hydrogen atoms and one of oxygen (H2O), while the heavy water is composed of two atoms of the isotope deuterium and one of oxygen (D 2 O).
  • Heavy water is 11% more dense than tap water.
  • The degree of acidity of heavy water is greater than that of normal water.
  • Heavy water is not drunk, while normal water is.
  • Ice floats in normal water, but not in heavy water.
