DAT GChem Section 7 Study Exam Questions Correctly Answered. What is the oxidizing agent in the following reaction?(7.1) 8H+(aq) + MnO4-(aq) + 5Fe2+(aq) → 5Fe3+(aq) + Mn2+(aq) + 4H2O(l) - CORRECT ANSWER MnO4- The oxidizing agent (or oxidant) is the species that gets reduced (gains electrons) First of all the oxidant or reductant is always a reactant so Mn2+ can be eliminated. H+ is not oxidized or reduced. MnO4- -->Mn2+ : +7 -->+2 MnO4- is reduced and is therefore the...
