Construction and Working of Leclanche Cell

Construction and Working of Leclanche Cell Points : Construction and Working of Leclanche Cell, Electron Exchange, Chemical Reaction Construction Leclanche Cell is consists of a positive carbon electrode packed into a combination of MnO₂ and powder carbon in a porous pol. The negative Zinc electrode dipped in standard solution of NH₄ Cl. Working Electron Exchange It occurs when Zinc metal gives up electrons at negative terminal and Zinc ions. Zn → Zn⁺⁺ + 2e Chemical Reaction 2MnO₂ + 2NH₄ CI + Zn → Mn₂ O₃ + H₂0 + ZnCL₂ + 2NH₃
