what is the activity series used for
The activity series is a useful guide for predicting the products of metal displacement reactions. For example, placing a strip of zinc metal in a copper(II) sulfate solution will produce metallic copper and zinc sulfate, since zinc is above copper on the series.op-ranked metals displace the ions of metals lower in the series from solution. A free-energy based series is used in this tutorial to show how and why active metals displace less active ones from solution.
