H2o dry cell
WebThe anode and cathode reactions for the dry cell are given below. (anode) (cathode) Zn (s) → Zn2+ (aq) + 2 e- 2 NH4+ (aq) + 2 MnO2 (s) + 2e- Mn2O3 (s) + H2O + 2NH3 (aq) One disadvantage of the dry cell is that the ammonia produced at the cathode corrosive to the zinc can that serves as the anode, which leads to leaks.
