Depict the galvanic cell in which the reaction
takes place. Further indicate what are the carriers of current inside and outside the cell. State the reaction at each electrode.
takes place. Further indicate what are the carriers of current inside and outside the cell. State the reaction at each electrode.
Solution
Cell representation:
Current carriers: in the external circuit, electrons flow from zinc (anode) to silver (cathode); inside the cell, the current is carried by the ions moving through the solutions and the salt bridge.
Electrode reactions:
Anode (oxidation):
Cathode (reduction):
