Transcribed Image Text:/ Consider the unbalanced reaction below, which occurs in an acidic aqueous solution. MnO4 + 1 Ⓡ1₂ + Mn²+ a. Identify the half-reactions (oxidation, reduction) __ b. Balance the reduction equation c. Balance the oxidation equation d. Balance the overall equation
Expert Solution
Step 1

To balance the given reaction following steps must be followed-

  1. Divide the given reaction into two half cell reactions
  2. Balance the atoms other than H and O
  3. Balance the oxygen by adding H2O to the oxygen deficient side
  4. Balance the H by adding H+ to the hydrogen deficient side. To balance the hydrogen add OH-.
  5. Balance the electron on both sides
  6. Write the complete reaction by adding both the half-cell reactions.
