Water

The chemical formula of Water is H2O. It is made from 2 molecules of Hydrogen and one molecule of Oxygen.

Upon dissociation, the Water separates into gaseous Oxygen and Hydrogen. The dissociation of Water can be brought about by passing an electric discharge through it. Apart from its chemical importance, Water has immeasurable importance for supporting life on Earth. It can be found everywhere on the planet, ranging from marine ecosystems to arid deserts. It is present in every part of the Earth in some form or the other. In oceans and lakes, it is found in liquid form, whereas, in Polar Regions, it is found in solid form. Traces of Water are found in the atmosphere and outer space in the form of gaseous water vapor. The surface of the Earth is composed of 3 parts of water and one part land. This shows that Water is highly important for all living beings. The only reason why life formed on Earth in the first place is Water. Finding Water anywhere else in the universe is next to impossible. So we must make sure that we conserve this liquid treasure so that our future generations would be able to use it too.

Water is recognized as a universal solvent. This characteristic of Water makes it so important for life on Earth to flourish. It has two molecules of Hydrogen joined by double covalent bonds with a single molecule of Oxygen. The covalent bonds give Water its solubilizing properties. It can dissolve a large number of solids, liquids, and gases within itself. Our bodies require 70% of Water to function properly. Most of this Water is used for transporting nutrients to different parts of our bodies and bringing back toxins from them that would be ultimately excreted out.

Water is found in abundance on the Earth but, only 1 percent of it can be used for drinking purposes. This 1 % is known as potable water and is found in freshwater resources like glaciers, streams, lakes, rivers, and ponds. With time, the share of clean freshwater has been deteriorating. Most of the freshwater that we use comes from rivers and underground reservoirs. Overexploitation of these resources has led to a decrease in water levels in these bodies.
