Alkaline water is water that’s less acidic than regular tap water. This means it is rich in alkalizing compounds, including calcium, silica, potassium, magnesium, and bicarbonate.
Ionized Water (Alkaline Water)
Despite being described as ‘water ionizors’ the machines are designed to work as water electrolysers. This is an electrochemical process in which water is split to form hydrogen and oxygen by an electric current. The overall chemical reaction is shown below:
2 H2O(l) → 2 H2(g) + O2(g)
During this process the water near the anode is acidic while the water near the cathode is alkaline. Water ionisers work by simply syphoning off the water near the cathode. This contains increased levels of hydroxide (OH−) and would be expected to have a higher pH (i.e. be more alkaline).
