WebCorrect option is A) The unbalanced redox equation is as follows: MnO 2+H 2O 2→MnO 4−+H 2O. All atoms other than H and O are balanced. The oxidation number of Mn changes from 4 to 7. The change in the oxidation number of Mn is 3. The oxidation number of O changes from -1 to -2. The change in the oxidation number of one atom of O is 1. WebQuestion: A voltaic cell is constructed using the half-reactions below: E° = +1.23 V MnO2 (s) + 4H+ (aq) + 2e --> Mn2+ (aq) + 2H2O(1) TiO2+(aq) + 2H+ (aq) + 4e --> Ti(s) + H2O(1) E° = -0.88 V a. Write the equation for the reaction that produces a positive standard potential and then calculate that potential (show half cell reactions and over-all reaction).
