In any electrochemical cell (electrolytic or galvanic) the electrode at which reduction occurs is called the cathode. The positive electrode, on the other hand, will attract negative ions (anions) toward itself. This electrode can accept electrons from those negative ions or other species in the solution and hence behaves as an oxidizing agent.
