Shown below is a galvanic cell with anode compartment b containing anode a and cathode compartment d containing cathode c. Electrons flow through wire f, ions flow through salt bridge e, and the cell potential is read using voltmeter g. This galvanic cell uses the reaction: Cu(s)+2Ag+(aq)→2Ag(s)+Cu2+(aq) ... show more Shown below is a galvanic cell with anode compartment b containing anode a and cathode compartment d containing cathode c.
