A water ionizer is a home appliance which claims to raise the pH of drinking water by using electrolysis to separate the incoming water stream into acidic and alkaline components. It is also can be named alkaline ionizer. Proponents claim that consumption of the alkaline stream. And in the results it has variety of health benefits. There is making it similar to the alternative health practice like alkaline diets. Such presents are not accepted in chemistry and physiology sciences, and evidence-based medicine.

First of all, the machines became popular in Japan and other far eastern countries before becoming available in the U.S. and Europe.


Processes of water ionizers

Being described as ‘water ionizers’ the machines are designed for working as water electrolyzers because of this is an electrochemical process. In its process water is split to form hydrogen and oxygen by an electric current. During this process, the water near the anode is acidic while the water near the cathode is alkaline. Water ionizers work by simply siphoning off the water near the cathode. Water siphoned off the cathode side contains increased levels of hydroxide (OH) and would be expected to have a higher pH (i.e. be more alkaline), whereas water siphoned off near the anode would have increased levels of H+ making it acidic. The acidic water is claimed to be useful for household disinfecting and safe for drinking. The effectiveness of the process is debatable because electrolysis requires significant amounts of time and power; hence, the amount of hydroxide that could be generated in a fast moving stream of water such as a running tap would be minimal at best. Additionally, the process of reversing the reaction requires much less energy, so if the area between the alkaline and acidic water is at least semi-permeable, the water will undergo another reaction that just leaves neutral water. Similar machines have been used to produce electrolyzed water which is chemically much different because it also contains sodium hypochlorite, the main ingredient in bleach, and may therefore be used as a disinfectant.

Health presents.

Water ionizers are often marketed on the basis of health claims which are normally focused on their putative ability to make water more alkaline. A wide variety of benefits have been claimed, including the ability to slow aging, prevent disease, offer protection from nuclear fallout, give the body more energy, and offset the effects of acidic foods.

There is no empirical evidence to support these claims, nor the claims that drinking ionized water will have a noticeable effect on the body. Drinking ionized water or alkaline water does not alter the body’s pH due to acid-base homeostasis.
