Describe what it is meant when water is called a polar molecule?

Water is the universal solvent that has the ability to dissolve almost all the substances. Water is made up of the hydrogen and oxygen element in the ratio of 1:2.

Hydrogen is a polar solvent as it contains the more electronegative element oxygen and the electropositive element Hydrogen. The electronegativity difference between hydrogen and oxygen makes hydrogen slightly positively and oxygen slightly negatively charged. The polarity of water molecule makes it a polar molecule.

Water is called a polar molecule because the oxygen atom is more electeonegative than the hydrogen atoms.
