Solution:
An oxidising agent is the species which is reduced in a chemical reaction, while a reducing agent is the species which oxidizes in the reaction.
Therefore,
A) MnO4- + Fe2+ = ? + ?
Oxidation number of Mn = +7
Oxidation number of Fe = +2
Hence, higher oxidation number of Mn suggesting that it will reduced and hence MnO4- works as oxidising agent, while Fe2+ is oxidized into Fe3+. Therefore, Fe2+ is reducing agent.
B) MnO4- + Fe2+ (aq) = Mn2+ + Fe^3+
MnO4- = oxidising agent
Fe2+ = reducing agent
C) Cr2O7^2+ + NO2- = 2Cr2+ + NO3
Cr2O7^2+ = oxidising agent
NO2- = reducing agent
D) Cr2O7^2+ + Fe2+ = 2Cr2+ + Fe3+
Cr2O7^2+ = oxidising agent
Fe2+ = reducing agent
E) NO3- + I- = NO2 + IO3-
NO3- = oxidizing agent
I- = reducing agent
