Question:
Refer to Example 23-2. Select a reducing agent (from Table 23.1 or Appendix D) that will reduce VO2+ to V3+ and no further in acidic solution.
Example 23-2
Can MnO4–(aq) be used to oxidize VO2+(aq) to VO2+(aq) for standard-state conditions in an acidic solution? If so, write a balanced equation for the redox reaction.
