Latimer Diagrams • written with the most oxidized species on the left, and the most reduced species on the right • you can determine whether a species in an intermediate intermediate oxidation state will disproportionate disproportionate , ie, convert to the more oxidized species oxidized species to its left and the more reduced species reduced species to its right, by comparing the redox potential for its formation vs . the redox potential for its reduction O 2 +0.70 V H 2 O 2 +1.76 V H 2 O (0) (–1) (–2) oxidation state
