What is the oxidizing agent in the redox reaction represented by the following cell notation? Mn(s)∣ Mn²⁺(aq) K⁺(aq)∣ K(s) A) Mn(s) B) Mn²⁺(aq) C) K⁺(aq) D) K(s) E) Pt

Question

Quizplus · Accepted Answer

The oxidizing agent is the substance that is reduced in the redox reaction. In this case, the cathode half-cell shows the reduction of K⁺(aq), which means this species is accepting electrons and being reduced. Therefore, the oxidizing agent is the other species in the reaction, which is Mn²⁺(aq).
