Frost diagram
A Frost diagram or Frost-Ebsworth diagram is a type of graph used by inorganic chemists in electrochemistry to illustrate the relative stability of a number of different oxidation states of a particular substance. Frost diagrams will be different at different pHs, so the pH must be specified.

Used frequently in electrochemistry, half-reactions of oxidation-reduction reactions have reduction potentials that determine the increases or decreases in free energy. The Frost diagram allows easier comprehension of these reduction potentials than the earlier-designed Latimer diagram, because the “lack of additivity of potentials” was confusing. Frost introduced this diagram as a qualitative substitution for the Latimer, and graphs oxidation state vs. free energy. The free energy Δ''G''° is related to reduction potential ''E'' in the graph by given formula: Δ''G''° = −''nFE''° or ''nE''° = −Δ''G''°/''F'', where ''n'' is the number of transferred electrons, and ''F'' is Faraday constant (''F'' = 96,485 J/(V·mol)).
