The 'experiment' was extremely half-a**ed. I used salt simply because I couldn't be bothered to get the NaOH from the shelf, and the experiment was only intended to last five minutes, and the room is extremely well ventilated, my skin is like an alligator's and my lungs are made of stainless steel.

I wired a 12 Volt battery via a voltmeter for the simple reason the volt meter has croc clips so I could easily connect some power to the disks.

I know about the chlorine risk, but thanks for the warning anyway.

* But could you answer the question about the missing coating from the anode, and the yellow-green scum on top after I called it quits, please?

Since there is no edit feature, I will repost:




Sorry, I guess I misunderstood. I would keep that solution, and keep collecting it. I am toying with platinum plating right now, but its an expensive time-consumer when I have other projects that really need to be done first.

Here is a hint. The Romans used to coat their iron weapons with COPPER by putting them in a bath of vinegar, salt, and copper chunks. I accidently discovered this while running acetic acid and salt on a rusted car panel using a pump and hose with a copper nozzle. It removed the rust off the steel, and copper plated my body panel, lol.
