What is the main function of a cathode in an electrochemical cell?

Step 1: Understand what an electrochemical cell is. It is a device that converts chemical energy into electrical energy.
Step 2: Identify the two main parts of an electrochemical cell: the anode and the cathode.
Step 3: Know that the cathode is the electrode where a chemical reaction occurs.
Step 4: Learn that at the cathode, a process called reduction takes place. This means that the cathode gains electrons.
Step 5: Remember that gaining electrons is important because it helps create electrical energy in the cell.
