The Mechanism of Ion Exchange. As a result atoms or groups of atoms are released into solution. Very pure water contains only water molecules (H2O) which are electrically neutral, with a very small proportion of the water molecules broken down into two fragments, one positive hydrogen ion (H+) and one negative hydroxyle ion (OH-).

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key.

For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen. The atomic number corresponds to the number of protons and is found.
