In a battery,the following two oxidation-reduction reactions are taking place: rxn A: Zn → Zn⁺² + 2e^-
Rxn B: 2 NH₄⁺ + 2e^- → 2 NH₃ + H₂
Which reaction is taking place at the anode?

In a battery,the following two oxidation-reduction reactions are taking place: rxn A: Zn → Zn⁺² + 2e^- Rxn B: 2 NH₄⁺ + 2e^- → 2 NH₃ + H₂ Which reaction is taking place at the anode?

Quizplus · Accepted Answer

In a battery, the oxidation reaction takes place at the anode and the reduction reaction takes place at the cathode. In the given reactions, Zn is being oxidized to ZnS in reaction A, while in reaction B, NHS1U1B14S1U1B0S1U1P1 is being reduced to NHS1U1B13S1U1B0. Hence, reaction A is taking place at the anode where oxidation occurs.
