I can tell you it wasn't from electrolysis of water. That produces hydrogen
(H2) and oxygen (O2), not acid and base. Anything else would have to come
from additives to the water.


it's sal****er.

I'm curious when this was patented, if it was.

Apropos electrolysis and water, way back in the day in high-school, my chemistry teacher showed us how to make Hydrogen peroxide using electrolysis. It was crude and not very efficient, and wasteful of resources.

Today, not so much.

Under controlled conditions, other products are also possible. I suspect that is what Tennant was doing.

Side Note: This teacher partnered with several of the history teachers. He had us collect 'night soil' to make gunpowder when we were studying the Civil War, we had to learn the 'secret code' whereby one could identify an American anywhere, any time (this _was_ the 1960s, remember), and we had to learn the ten (10) reindeer. In any case, a lot of very basic and very useful chemistry and applied science has stuck with me over the years.

Apparently anyone can be an expert on things they do not understand.

As Rickman and Oldschool constantly prove.

It's where lye and chlorine bleach come from.

and has been an industrial process since the 1890s. I'm sure there's bunches
of patents...

Not really. All water has contaminants. The water he has mentioned was
fresh water with more or less contaminants. Still, it wouldn't be described
as electrolysis of (salt)water if the interesting part was the contaminants.
It would be described as the interesting bits dissolved in water.


Are you trying to be stupid today?

Much as I hate to admit it, Oldschool does display actual curiosity, and some capacity for learning.

To the extent that I take any time at it at all, I still wonder if Ricky is any of these:

12 years old, or less. This would cover it all.
Deep into the spectrum. However, these sorts tend to be savants at something.
Really that ignorant, or just tweaking us.
