MHT CET 2025 Chemistry question

Which of the following change takes place at positive electrode during working of dry cell?

(A) is oxidised to
(B) is reduced to
(C) is reduced to Correct
(D) is oxidised to

Answer: (C)

Solution

In a dry (Leclanche) cell the zinc container is the anode (negative electrode) where oxidation occurs, . The positive electrode is a graphite rod surrounded by a paste of and carbon, where reduction occurs: 2MnO_2 + Zn^{2+} + 2e^- \rightarrow Mn_2O_3 + ZnO (in the
