Q: What is the role of a cathode in an electrochemical cell?
Solution:
The cathode is the electrode where reduction occurs, gaining electrons from the external circuit.
Steps: 6
Show Steps
Step 1: Understand that an electrochemical cell has two electrodes: an anode and a cathode.
Step 2: Know that the cathode is the electrode where a chemical reaction takes place.
Step 3: Remember that in the cathode, a process called reduction occurs.
Step 4: Realize that reduction means gaining electrons.
Step 5: Understand that these electrons come from an external circuit.
Step 6: Conclude that the cathode is important because it helps in the flow of electricity by gaining electrons.
