Questions & Step-by-Step Solutions

In electrochemical cells, what is the role of the cathode?
  • 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 anode is where oxidation occurs, meaning it loses electrons.
  • Step 4: Learn that the cathode is the opposite of the anode.
  • Step 5: Recognize that at the cathode, reduction takes place, which means it gains electrons.
  • Step 6: Conclude that the role of the cathode is to accept electrons and facilitate the reduction reaction.
