What is the role of the cathode in an electrochemical cell?

Step 1: Understand what an electrochemical cell is. It is a device that converts chemical energy into electrical energy or vice versa.
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 reduction occurs. Reduction means gaining electrons.
Step 4: Remember that in a galvanic (voltaic) cell, the cathode is positive, while in an electrolytic cell, it is negative.
Step 5: Realize that the cathode attracts cations (positively charged ions) from the solution.
