Of the three metals, #Pb, Cu, Zn#, which is the most active?

Zinc. Copper is the least active of these three. I base this choice on the one type of reaction that metals typically undergo - oxidation. If you consult a list of what is known as "reduction potential", and which is very useful in determining the manner in which chemicals oxidize or reduce, you find that zinc is considerably more prone to oxidation …
