abstract = {Chemists and materials scientists often use the concept of oxidation states, the number of electrons a species has effectively gained or lost, to understand and predict chemical reactions and material properties. The list of chemical species sorted by how easily they gain electrons is known as the electrochemical series. The standard electrochemical series is largely based on data in aqueous solutions, which does not always translate well to solid-state materials.

The electrochemical series is a useful tool in electrochemistry, but its effectiveness in materials chemistry is limited by the fact that the standard electrochemical series is based on a relatively small set of reactions, many of which are measured in aqueous solutions.
