Sorry, I just realilzed I sent the first version without converting to plain
text.
Chemistry in the community has an experiment like this without the NaOH.
They use 1 M zinc chloride with mossy zinc and boil the pennies for 5 to 10
minutes. Just did it today and worked on every penny. Pennies are cleaned
with 1 M HCl prior to putting into zinc chloride solution. I assume you put
the penny on the hot plate after plating to make brass?
