Home › NEET UG › Chemistry › Electrochemical Series ›  In a Leclanche (dry) cell, the anode and the depolariser/cathode reactive species are respectively:
ACu container (anode) and MnO₂ (cathode)
BPb (anode) and PbO₂ (cathode)
CCarbon (anode) and Zn (cathode)
DZn container (anode) and MnO₂ in a paste of NH₄Cl + ZnCl₂ (cathode)
Answer & Solution
Correct answer: D. Zn container (anode) and MnO₂ in a paste of NH₄Cl + ZnCl₂ (cathode)
Dry cell: **Zn container = anode**, central carbon rod surrounded by **MnO₂ + carbon in NH₄Cl/ZnCl₂ paste = cathode**. EMF ≈ 1.5 V. Mn reduced from +4 → +3 at cathode. (Pb/PbO₂ is the lead-acid battery.)
