Sulfuric acid

So there's the copper sulfate electrolysis for prepraring sullfuric acid, which is diluted and needs distillation, but there are videos out there of using cheap magnesium sulfate in with a clay pot to separate the electrodes.

Given that a single Nafion membrane, not a set, should be affordable, and you only need to separate the two cells, could it be possible to just use it or anyt other cation-exchange membrane, and collect the sulfuric acid at the anode?

I do believe that a youtuber called ScrapScience (or scrap science, I forget) does have several videos on making sulfuric acid (a dilute solution of around 20 to 21%) using Epsom salt (magnesuim sulfate as you mentioned).


Here is the link to his youtube channel. https://www.youtube.com/channel/UCYLvqqVn7Un9lafEXwSW4mA

Yes I saw it. But in what video does he say it is a 20% concentration?
