The series is also called the replacement series, since it indicates which metals replace, or are replaced by, other metals or hydrogen in compounds.

In general, a metal will replace any other metal lower in the series and will be replaced by any metal higher in the series. The order of some common metals in the electromotive series, starting with the most easily oxidized, is: lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, chromium, iron, cobalt, nickel, lead, hydrogen, copper, mercury, silver, platinum, and gold.

A list arranged according to oxidation potential and including not only metals but also all other elements and ions is called the electrochemical series. Which metal ion, Au or Li, is more easily reduced? Which metal ion has the MOST positive reduction potential? Which metal ion, Au or Li, makes a better oxidizing agent? This is the same question asked in the previous problem!

C onsider the following table of standard reduction potentials:.
