Unit 9.8: Galvanic (Voltaic) and Electrolytic Cells
Identify the components of an electrochemical cell and the role each
part plays.
- What is the function of the salt bridge in a galvanic cell?
-
How does the anode differ from the cathode in terms of electron flow?
Determine the direction of electron flow in an electrochemical cell.
- In a Zn-Cu galvanic cell, which direction do electrons flow?
- Why do electrons always flow from the anode to the cathode?
Represent an electrochemical cell with an appropriate particle diagram.
-
Draw the movement of Zn²⁺ and Cu²⁺ ions during the operation of a
Zn-Cu cell.
-
What happens to the size of the Zn and Cu electrodes as the cell runs?
Label the anode and cathode with the corresponding redox process.
- Which electrode is oxidation occurring at in a galvanic cell?
- Why is the cathode associated with reduction?
