In a dry cell the zinc cylinder serves as the
WebIn cylindrical Leclanché cells, zinc serves as anode and cell container. The cathode mixture (manganese dioxide and acetylene black) forms a bobbin with a centrally located carbon rod as current collector. WebAug 9, 2024 · In the zinc-carbon dry cell, the anode is a zinc container, while the cathode is a carbon rod through the center of the cell. The paste is made of manganese (IV) oxide ( MnO 2), ammonium chloride ( NH 4 Cl), and zinc chloride ( ZnCl 2) in water. The half-reactions for this dry cell are: Anode (oxidation): Zn ( s) → Zn 2 + ( a q) + 2 e −
