If the hydrogen disappears immediately after production (out of the machine) then why does the water test higher in pH later on?
A. pH does not measure the concentration of molecular hydrogen (H2) only the ratio of H+ to OH- ions. H+ ions react with environment faster than OH- causing an alkaline boost after electrolysis. This is an indicator of unstable pH. Q. What is the difference between stable and unstable pH. A. pH is the measure of difference in concentration of H+ and OH- ions. More OH- is alkaline. OH- can be created by electrolysis or as a reaction between alkaline earth metals like magnesium and water. All systems are open with respect to the environment. Electrolysis ionized water OH- concentration is fixed and thus dissipates with time. As a result of magnesium reaction with water, OH- reaches concentration and the reaction stops. When OH- dissipates with environmental interaction and the concentration decreases, reaction starts up again, therefore, a stable pH results in more alkalinity than you see with a meter and is a better utilized alkaline resource for the body.
