The standard potentials for two nonadjacent species can also

Last updated: 7/3/2023

The standard potentials for two nonadjacent species can also be calculated by using the concept that AG as an additive property but potential is not an additive property and AG nFE If a given oxidation state is a stronger oxidising agent than in the next higher oxidation state disproportionation can occur The reverse of disproportionation is called comproportionation The relative stabilities of the oxidation state can also be understood by drawing a graph of AG F against oxidation state known as Frost diagram choosing the stability of zero oxidation state arbitrarily as zero The most stable oxidation state of a species lies lowest in the diagram Disproportionation is spontaneous if the species lies above a straight line joining its two products species Question 32 Which of the following couple have same value of potential at pH 0 and pH 14 Options CIO CIO
