What is the reduction half-reaction for the reaction between iron(II) sulfate and potassium permanganate in a sulfuric acid solution?
5Fe2+(aq) + MnO4–(aq) + 8H+(aq) --> 5Fe3+(aq) + Mn2+(aq) + 4H2O(l)

a. MnO4– + 3e– -->Mn2+(aq) + 4H2O
b. MnO4–(aq) + 8H+(aq) + 5e– -->Mn2+(aq) + 4H2O
c. MnO4–(aq) + 5e– -->Mn2+(aq) + SO42–(aq)
d. Fe2+(aq) + 2e– -->Fe(s)
e. 5Fe2+(aq) -->5Fe3+(aq) + 5e

In an acid solution, MnO4^- is reduced to Mn^+2.
MnO4^- + 5e + 8H^+ ==>Mn^+2 + 4H2O
