Reading and Discussing an Article about Making a Homemade Voltaic Cell In the space provided, describe your sketch using terms you have learned in the lesson.

answer =
Zinc is the anode, and copper is the cathode.

The lemon flesh and juice provide the salt bridge and electrolyte solution.

Electrons flow from zinc to copper through the external wires.

Electrolytes flow in the lemon. Positive ions (cations) move toward copper electrodes (cathodes), and negative ions (anions) move toward zinc electrodes (anodes). These balance the charges building up.

Two cells in series provide more energy output than one. The clock may need more energy than can be supplied by one cell.

Batteries do not need external source of reactants, whereas a fuel cell must be supplied with reactants.
