Definition

The cathode is the electrode where reduction occurs in an electrochemical cell. It is the positive terminal in a galvanic cell.

5 Must Know Facts For Your Next Test

  1. In a galvanic cell, the cathode is the site of reduction reactions.
  2. Electrons flow toward the cathode from the anode.
  3. The cathode is typically marked as the positive terminal in a galvanic cell.
  4. Reduction at the cathode means that a species gains electrons.
  5. Common examples of reduction reactions at the cathode include $\text{Cu}^{2+} + 2e^{-} \rightarrow \text{Cu}$ and $\text{Ag}^{+} + e^{-} \rightarrow \text{Ag}$.
