Another chemistry club experiment!This week we stripped pennies of their copper (Cu) coating to expose their true composition underneath, zinc (Zn). This process was done with Nitric Acid.See week 1's video here:http://www.youtube.com/watch?v=jtDmpIh_WrUParts 2-5 of this experiment here:http://www.youtube.com/watch?v=-PVSWqnyhiAhttp://www.youtube.com/watch?v=mlPNmRjp9FYhttp://www.youtube.com/watch?v=5_g3cRRR__chttp://www.youtube.com/watch?v=10AvT6feXKA
