125 How does an ionizer work? A water ionizer is a small kitchen appliance that separates tap water into two separate streams - one alkaline and one acidic - through a process called electrolysis. Ionizers can either be installed on the counter next to the kitchen sink or under the counter with only a special faucet visible above the counter. Ionization breaks the bond between the oxygen and hydrogen atoms of a water molecule [H2O] and produces alkaline water full of hydroxyl ions [OH-] and and acid water full of hydrogen ions [H+]. What are pH and ORP? The pH scale measures how acidic or alkaline a substance is. It ranges from 0 to 14. A pH of 7 is neutral, a pH less than 7 is acidic, and a pH greater than 7 is
(or basic). ORP, or oxidation reduction potential, measures a substance's ability to oxidize or reduce molecules around it, or in other words, it's potential to steal or donate electrons. pH and ORP are key concepts to understand ionization and the important health benefits of alkaline ionized water. Water, the chemistry of life. Water is essential for life. No living being on planet Earth can survive without it. In fact, about 70 to 90 percent of all organic matter is composed of water. Water not only provides the medium to make life sustaining chemical reactions possible, but water itself is often an important reactant or product of these reactions. In short, the chemistry of life is water chemistry. This section provides some basic concepts that help to understand the chemistry of water and the science behind water ionization at the molecular level.
121 Americans spent $21 billion on bottled waters in 2012, and more and more consumers are investing in a home water filter. A filter can range from an inexpensive carafe or pitcher to a system designed for the whole house, but the latest machine to make waves is the water ionizer, which passes an electrical current through tap water in order to turn it alkaline (i.e., base) through the chemical reaction called electrolysis. Proponents claim alkaline water helps the body neutralize acid in the blood, provides more energy, slows the aging process, and is, according to the online purveyor Alkaline Water Plus, "packed with natural antioxidants [negatively-charged electrons], which are free to naturally fight free radicals .... Drinking
antioxidant water all day long will help you prevent and even reverse free radical damage." "Change your water, change your life," is the trademarked slogan of Kangen Water, marketed by the U.S. branch of the Japanese company Enagic. "Keeping ourselves Alkaline is the first line of defense in fighting any disease," Cal Water Systems states on another website. "Ionized Water essentially renews us at a cellular level. This is as close as we can ever hope to get to a Fountain of Youth, as incredible as that may sound." That does sound incredible. And expensive! Don't know about you, but it made me really curious about how water ionizers work. But first, a little background on the pH scale, which is used to define degrees of alkalinity and acidity. In 1909, S.P.L. Sørensen, director of chemistry at Carlsberg Laboratory, in Copenhagen (founded in 1875 by beer magnate J.C. Jacobsen), invented the pH scale while researching proteins, amino acids, and enzymes—the basis of protein chemistry today.
