Water is made of two atoms of hydrogen attached to one central atom of oxygen by covalent bond, making an angular spatial structure. The hydrogen atoms “lend” electrons to the oxygen and consequently the oxygen atom becomes more negative while the hydrogen ones become more positive. The spatial geometry of the water molecule makes it a polar molecule, with negative and positive poles.

Water is an excellent solvent for polar substances because the electrical activity (attraction and repulsion) of its poles helps in the separation and the mixing of these substances, giving them more movement and thus increasing the number of molecular collisions and the speed of chemical reactions. On the other hand, water is not a good solvent for non-polar substances.
