To Ionise means to gain or lose an electron. Essentially, the ionisation process robs an electron from one molecule and donates, or transfers, it to another molecule. In the case of Ionised Water, an electron is grabbed from one oxygen molecule and donated to another oxygen molecule. This becomes a hydroxyl ion, which is a molecule that carries an extra electron (OH-).
Although they are transitory, molecules with this charge produced by the presence of an electron are more easily absorbed by the body. The presence of hydroxyl ions makes the water alkaline, meaning it has a high pH. An excess of negatively charged hydroxyl ions results in a pH above 7.0. A deficit of electrons results in a low pH below 7.0. An equal amount of electrons in a solution or in the body results in a balanced pH of 7.0.
The other water produced during the ionisation process contains molecules that have been robbed of an electron. These are known as hydrogen ions (H+) and they are what make the water acidic, resulting in a low pH.
These yin/yang waters produced by ionisation are the exact opposite from one another. Both Alkaline and Acid Ionised Water have extraordinary properties and benefits, although their respective uses could not be more different. We consume the Alkaline Ionised Water. The Acid Ionised Water should never be consumed. Ionised Water has a beneficial effect on everything it comes in contact with as long as it is used properly.
