In the redox reaction involving the permanganate ion in acidic solution, permanganate ion is reduced to manganese (ii) ion while iron (ii) ion is oxidized to iron(iii) ion.
A redox reaction is a reaction in which reduction and oxidation occurs at the same time and to the same extent.
An example of a redox reaction is the reaction involving the permanganate ion and tetraoxosulphate (vi) ion in acidic solution.
The equation of the reaction is given below:
[tex]MnO_{4}^{ - } (aq) + 5Fe^{2+}(aq) + 8H^{+} \rightarrow Mn^{2+}(aq)+ 5Fe^{3+}(aq) +4H_{2}O(l) \\ [/tex]
Therefore, in the redox reaction involving the permanganate ion in acidic solution, permanganate ion is reduced to manganese (ii) ion while iron (ii) ion is oxidized to iron(iii) ion.
