In a dry cell the zinc cylinder serves as the
WebA cell of an alkaline battery is a section of the battery. In a chemical power supply, a dry battery is the primary battery. It’s a disposable battery of some sort. It converts chemical energy into electrical energy by using manganese dioxide as the positive electrode and zinc cylinder as the negative electrode to power an external circuit. WebMar 11, 2024 · In shorthand notation the dry cell corresponds to Zn│Zn 2+, NH 4+ │MnO 2 ( s ), C while the electrode half-equations can be represented as (1) Zn ( s) → Zn 2 + ( a q) + 2 e − and (2) 2MnO 2 ( s) + 2NH 4 + + 2 e − → 2MnO (OH) ( s) + 2NH 3 ( a q) in which the manganese is reduced from Mn (IV) in MnO 2 to Mn (III) in MnO (OH).
