zinc/copper/hcl - larsalan - 05-27-2011
I'm watching this modern marvels tv show about acids. They showed a scientist dissolving the zinc center of a penny away with hcl leaving only copper.
Do you think that I could do that large scale and scrap the copper? I think pre 1982 pennies are 100% copper too.
I know all of this is a felony. Just wondering. And I wonder how that guy could do it on tv.
How concentrated does the hcl have to be, how many pennies can it dissolve, and where can I get it?

Lol I just watched the exact same episode. The cost of pennies and acid would have you losing money, better off just collecting the pennies.

Yeah old ones, then get a crucible or something and have a hot ass campfire. Real caveman style. Copper is super high now for scrap. There was like $40 of wires in the dashboard of that 300d even covered in insulation they paid that.
That recycling center would be confused when you showed up with a big blob of copper.

Naysayers say that the old pennies are only 95% copper and that the recycling people will know you melted them. I would just tell them it was art, like a statue or something.
