Rank the given metal ions in order of increasing strength as an oxidizing agent.
Pb2+ (-0.13 V), Mn2+ (-1.18 V), Cu2+ (+0.16 V), Co3+ (+1.82 V), Fe3+ (+0.77 V)
Standard Reduction Potentials measure how easily a species can accept electron(s) from another species
Understanding Standard Reduction Potentials
Concept #1: The Standard Reduction Potential (Eºred) is measured under standard conditions: 25ºC, 1 atm, 1 M solution and pH = 7.
Recall, oxidation involves losing electrons and reduction involves gaining electrons.
Concept #2: The greater the Eºred the more likely reduction will occur.
Example #1: Determine which of the following will least likely donate an electron?
a) H2 b) Br2 c) Zn2+ d) Cl2 e) Li+
Determine which species can oxidize Br2.
