How do I test to see if something is copper?

Question

simple please

Answer 1

The non-silvery, copper color is one easy test.  Assuming you have some that you can disfigure or destroy, see if it bubbles in HCl.  If it doesn't react with HCl, but it does react with HNO3 to give a blue solution, then there is a 99.5 percent probability that it is copper.
