Galvanic (Voltaic) Cells Worksheet

What is the function of the anode in a galvanic cell?

• It is where reduction occurs.

• It prevents electron flow.

• It is where oxidation occurs.

• It acts as a salt bridge.

In a galvanic cell, which component allows for ion transfer?

• Salt bridge.

• Electrolyte

• Anode

• Cathode

What is the direction of electron flow in a galvanic cell?

• From cathode to anode.

• From anode to cathode.

• Through the salt bridge.

• In both directions.

Which material is commonly used as the electrode in a galvanic cell?

• Glass.

• Plastic.

• Metal (e.g., zinc, copper).

• Carbon.

What is reduced at the cathode in a galvanic cell?

• Water (H₂O).

• Electrons.

• Cations (e.g., Cu²⁺).

• Anions (e.g., Cl⁻).

What happens to the oxidation state of an element when it is oxidized?

• It remains the same.

• It decreases.

• It increases.

• It fluctuates.

Which of the following is a product of a galvanic cell reaction?

• Magnetism.

• Light.

• Electricity.

What is the purpose of the salt bridge in a galvanic cell?

• To store energy.

• To increase voltage.

• To connect the anode and cathode.

• To maintain charge balance.

What is the standard cell potential (E°) for a spontaneous redox reaction?

• Negative.

• Positive.

• Variable.

• Zero.

Which half-reaction occurs at the anode in a galvanic cell?
