1. The problem statement, all variables and given/known data Find the Ered° values in the appendix for the cathode and anode in the reaction 3Ce4+(aq) + Bi(s) + H2O(l) → 3Ce3+(aq) + BiO+(aq) + 2H+(aq) 2. Relevant equations None. 3. The attempt at a solution So in my appendix there is a value for the Ce4+/Ce3+ half-reaction, but only the reverse reaction for Bi(s) + H2O(l) → BiO+(aq) + 2H+(aq). What do you do then?
