Question

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 1

Answer: The following should be included in your description

• 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) moved 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
