Alkaline Water v.s Ionized Water

infographic difference between ionized water and alkaline water

The difference between alkaline water and ionized water is that ionized water has an electro-magnetic charge

Chemistry of Ionized Water and Alkaline Water

Alkalinity is a measure of the concentration of ions – ions are atoms that have gained or lost an electron – in any substance. The Potential Hydrogen (pH) of alkaline water refers to its potential to attract positively-charged Hydrogen ions (H+). Pure water has a neutral pH, but water in the real world isn’t pure, it contains minerals. The minerals in alkaline water give it an alkaline pH.

Ionization is the process used to change an atom or molecule into an ion by adding or subtracting an electron from that molecule or atom. Ionized alkaline water is water that has had its pH increased by ionizing the minerals in it. Minerals in alkaline water, like calcium, magnesium, and potassium, gain extra electrons when water is ionized.

The difference between alkaline and ionized water is: Alkaline water has alkaline minerals in it, ionized water has minerals in it that carry an electromagnetic charge.  Alkaline ionized water has alkaline minerals in it that have a negative electromagnetic charge.

Oxidation Reduction Potential

The negative electrical charge in alkaline water can be measured, just like the charge of a battery can be measured. The negative charge of ionized alkaline water that neutralizes free radicals is called its Oxidation Reduction Potential (ORP). In-vitro (in the lab) studies have shown that water with a high negative ORP, when mixed with a proton-donor such as vitamin C gains an enhanced antioxidant effect.
