[Geysers] Trader Joes ad

[Ott, Stephen]

Theoretically, this is possible but it does still have problems.

If you electrolyzed pure water (from reverse osmosis), you would produce only hydrogen gas and oxygen gas and pure water would remain.  However, pure water is such a non-conducting substance that I've never heard of it.  Maybe high voltages would cause it to occur.

If you really didn't purify the water very well (contrary to the claim), then it is possible that one hydrogen atom in each of two different HOH (H2O) molecules would be reduced to H2 gas and that another impurity would be oxidized such as chloride ion (Cl-) to chlorine gas, Cl2.  This leaves the other OH in the HOH to become OH-, which makes the solution basic, which raises the pH.  To raise the pH to 9.5 would be significant, but theoretically possible.  This electrolysis would take enough electricity that this would not be a cheap process.

As already mentioned, how could you have "electrolytes" after you had purified it with reverse osmosis?

Why would you want basic water doing it this expensive method?  Just add a little sodium bicarbonate (baking soda) to water and it dissolves nicely to give a basic solution and it is a descent antacid for upset stomach.

Yuh, that ought to be real good for your body. Sounds like a good hook if Michael Crichton ever wanted to do a sequel to The Andromeda Strain (you may remember, the pathogen could only survive in a very narrow pH range like 7.2-7.4).

The world just keeps getting weirder.

I know I'd get yelled at if I posted this on Facebook, but is this another example of the dumbing-down of America? In the "Trader Joe's Fearless Flyer Culinary Compendium,": Volume 7 -- 2015, page 16, is an ad for "Alkaline Water + Electrolytes." After noting that the bottle contents are 99.9% water and 0.1% minerals, the ad goes on to state this: (quote) "The mineralized water is purified through reverse osmosis, then run through electric currents (electrolysis), which changes the structure of the water and raises the pH to 9.5+..."

Emphasis mine, as I make no further comment.
