Question 11 • EDG CHEM ES W/LABS2(P) – Q2_9
An oxidizing agent is the species that gains electrons, so compare how readily each ion is reduced. The standard reduction potential for Mn²⁺/Mn is about −1.18 V, which is more positive than the −2.37 V for Mg²⁺/Mg. Therefore, Mn²⁺ is more readily reduced and is the stronger oxidizing agent.
