Universal solvent

Why Water is Called the Universal Solvent? First, we must understand what is solvent and solute?

Solvent is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature. Solute is a substance dissolved in fluid, forming a solution.

Water is a non-ionic polar molecule. So it will dissolve anything which will be similar to it. Actually, the molecule of water is made of two atoms hydrogen and oxygen. Out of these oxygen atoms are negatively charged whereas the atom of hydrogen carries a positive charge. As both the charges are weak, it makes the molecule neutral in itself.

It is because of the same reason that water is able to dissolve all those substances which are of the similar type. Thus, water dissolves more of the substances rather than the liquids in it. It is for the same reasons humans require more of water rather than any other substance.


Actually, we take in a lot of chemicals and other toxins in our food and also with the air. When all these toxins reach our kidneys, they are purified with the help of water only.

Water being the universal solvent dissolves all those components which are of the same pH as it and rest all other which are left behind are thrown out of the body in the form of urine
