Affects of Vitamin C on Penny Oxidation
+++
I am starting a science fair project "The affects of vitamin C on
penny oxidation". I have discovered that pennies prior to 1982 are
copper where current pennies have are zinc with a copper coating. I
am in the 6th grade and I believe I should use one or the other. Do
you think it would be better to use the copper pennies or the copper
coated pennies? Also, I have read conflicting articles about "copper
oxidation" can copper oxidize and why or why not or where is a
reliable source to find this information.
Thanks for you help,
