$begingroup$ @user2612743 In an electrolytic cell you are the person that determines which electrode is positive and which is negative via the external potential. And this external potential doesn''t get altered in the course of the reaction because the "sucked in" electrons are transported away by the voltage source.

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. In any electrochemical cell the anode is the electrode at which oxidation occurs. An easy way to remember which ...
