Frost diagrams: In a Frost diagram, we plot ΔG°⁄F (= nE°) vs. oxidation number. The zero oxidation state is assigned a nE° value of zero. [2] Stable and unstable oxidation states can be easily identified in the plot. Unstable compounds are higher on the plot than the line connecting their neighbors.. Page 2 of 11 Frost diagrams1 provide a visual representation of reduction potentials and relative thermodynamic stabilities of different oxidation states of an element in aqueous conditions. In these 25 diagrams (Figure 1), the oxidation number (N) of a common species (e.g., Fe2+ aq) is plotted on the x-axis

Using a Frost diagram, predict the final oxidation states of the RedOx couple at the end of the reaction in acidic solution. If there is no reaction, simply state "No Reaction". Do not balance the reactions. 1. Co(+3) + Ni →.. Frost diagrams provide convenient illustrations of the aqueous reduction potentials and thermodynamic tendencies of different oxidation states of an element. Undergraduate textbooks often describe the lowest point on a Frost diagram as the most stable oxidation state of the element, but this interpretation is misleading because the thermodynamic stability of each oxidation state depends on the.
