Caption: Demonstration of the voltage generated by a galvanic cell. The beakers contain solutions of zinc sulfate (left) and copper sulfate (right), linked by a salt-saturated bridge of wet paper. A voltmeter is connected to two electrodes, of zinc metal in the zinc solution and copper in the copper solution. When the zinc electrode is placed in the solution, a voltage is seen on the voltmeter. This is produced as the metals undergo reduction-oxidation (redox) reactions, with the most electronegative metal reducing the other. This generates a flow of electrons and ions around the circuit.
