What is Electromotive Series?

The electromotive series, also known as the activity series or electrochemical series, is a ranking of elements (usually metals) in order of their standard electrode potentials. Elements higher on the series have a greater tendency to lose electrons (be oxidized) and will displace those lower in the series from solution. The series is fundamental in predicting the outcomes of single displacement reactions and galvanic cell voltages.
