Redox reaction play a vital role in chemistry and biology. The values of standard redox potential (E°) of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniell cell in which zinc goes into solution and copper gets deposited. Given below are a set of half-cell reactions (acidic medium) along with their E° (V with respect to normal hydrogen electrode) values.
Q.
While Fe3+ is stable, Mn3+ is not stable in acid solution because
  • a)
    O2 oxidises Mn2+ to Mn3+
  • b)
    O2 oxidises both Mn2+ to Mn3+ and Fe2+ to Fe3+
  • c)
    Fe3+ oxidises H2O to O2
  • d)
    Mn3+ oxidises H2O to O2
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Redox reaction play a vital role in chemistry and biology. The values ...
For the reaction,

As evidenced above, reaction (i) is non-spontaneous, therefore, Fe3+ is stable in acid solution. However, reaction (ii) is spontaneous Me3+ oxidises H2O to O2 and itself reduced to Mn2+ in acidic medium.
