Anode vs cathode
Is the anode always the side of the oxidation half-reaction and the cathode, the side with the reduction half reaction?

Re: Anode vs cathode
Yes, that is true. The anode is always the oxidation half reaction and the cathode corresponds to the reduction half reaction.

Re: Anode vs cathode
I believe you are right. In a galvanic cell, the anode side is the oxidized side, as electrons flow out towards the cathode, or reduced, side. Therefore you would be right; the oxidation half reaction would be the anode side and the reduced half reaction would be the cathode side.

Re: Anode vs cathode
Also, the anode, oxidation half reaction, is always on the left, while the cathode, reduction half reaction, is always on the right.

Re: Anode vs cathode
An easy way to remember this is with "AN OX" (anode/oxidation), "RED CAT" (reduction/cathode)

Re: Anode vs cathode
You are correct. The anode is the oxidation side as it loses electrons, while the cathode is the reduction side as it releases electrons.

Re: Anode vs cathode
Side note: an easy way to remember that oxidation is the loss of e- and reduction is gain of e-, use OIL RIG. OIL = Oxidation Is Loss, RIG = Reduction Is Gain
