If you've been following the news lately, you've probably heard of the word "vitriol" being used as a political weapon, with people like celebrity left-winger Jane Fonda blaming conservatives like Sarah Palin for "vitriolic" attacks on Democrats and the "violence-provoking rhetoric of the Tea Party" movement for the recent Arizona shooting.
Vitriol is the historic name for sulfuric acid (sulphuric acid), a strong mineral acid frequenting chemistry labs, with the molecular formula H2SO4, comprised of hydrogen and sulfate. Vitriol is used in a large variety of applications, like lead-acid vehicle batteries, fertilizer, ore processing, oil refining and chemical synthesis. And guess what? You can make your own sulfuric acid, right at home!
It's a very useful acid, and there are actually many methods of making vitriol.
This method from NurdRage involves a sulfur dioxide generator, which in this case is a three-necked flask filled with 50g of sodium metabisulfite, a stir bar and 50mL of water. One one side, hook up a gas adapter and outlet tube.
And that's just the beginning. Watch the video to see the full instructions on making some DIY concentrated sulfuric acid from sodium metabisulfite, hydrochloric acid and an oxidant (hydrogen peroxide or nitric acid).
In the previous video, you saw NurdRage make sulfuric acid with a complicated sulfur dioxide and oxidizing liquid setup. For homebrew chemists, it might have been a little difficult to build.
Possibly a cheap way to make vitriol? Yes. So, in the following video, you'll see how to convert copper sulfate back into copper metal and sulfuric acid via some helpful electrochemistry.
Watch the full video below to learn the electrochemical method. You'll need some carbon electrodes (or platinum electrodes), copper wire, tape, power source, copper sulfate and filter.
