Re: Anode and Cathode
Yes. By definition, oxidation always occurs at the anode and reduction at the cathode. Therefore, electrons flow from the anode to the cathode.

Re: Anode and Cathode
Hey Alen!
Yea, the anode side is always the oxidation side and the cathode side is always the reduction side. Note that the word "anode" refers to the electrode that is on the oxidation side, and the word "cathode" refers to the electrode that is on the reduction side. This is important because if you have a half-reaction where there are no inert metal conductors present (like H+ + 2e- --> H2), your electrode would not be participating in the reaction (for this hydrogen half-reaction a platinum electrode will conduct electrons but not lose/gain any). So instead of saying the electrodes are either oxidizing or reducing, I'd recommend you think about it in terms of what side of the cell they are on: the anode is in the oxidation side and the cathode is in the reduction side of the galvanic cell.

Re: Anode and Cathode
Yes. This is always true. The anode is for oxidation, and the cathode is for reduction.

Re: Anode and Cathode
An anode will oxidize, and the cathode will reduce. I like to use the vowels in anode (a) and oxidize (o) to cement this relationship.

Re: Anode and Cathode
Yes, the anode always undergoes oxidation and the cathode always undergoes reduction. Also, in cell diagrams, the reduction is usually on the right and the oxidation is usually on the left. Hope this helps!

Re: Anode and Cathode
Yep, keep the anode on the left and remember that the oxidation is occurring there. The right is for the cathode where reduction happens.

Re: Anode and Cathode
By their definition, the anode is being oxidized and the cathode is being reduced. So, yes.

Re: Anode and Cathode
Yes. The flow of electrons therefore goes from the anode to the cathode, so the anode is oxidized while the cathode is reduced. The anode should also be on the left.

Re: Anode and Cathode
Yes, an anode is where oxidation occurs, and a cathode is where reduction occurs!

Re: Anode and Cathode
Yes, anodes are where oxidation occur and cathodes are where reduction occurs. In a galvanic cell and in a cell diagram, the anode is always on the left and the cathode is always on the right.

Re: Anode and Cathode
Hi! The anode is always the site of oxidation and the cathode is always the site of reduction.

Re: Anode and Cathode
Yes! The anode is oxidized (loses electrons) and the cathode is reduced (gains electrons). So the electrons flow from the anode to the cathode.

Re: Anode and Cathode
Yes, the anode is where oxidation occurs (loss of electrons), and the cathode is where reduction occurs (gaining of electrons). Thus, the electrons will always flow from the anode to the cathode.

Re: Anode and Cathode
Yes! Oxidation would occur at the anode and reduction would occur at the cathode.

Re: Anode and Cathode
That's right, since the loss of electrons occurs through oxidation, the process is carried out in an anode, while the gaining of electrons occurs through reduction, which is carried out in a cathode.

Re: Anode and Cathode
Yes, the acronym ANOX REDCAT helps me remember. Anode=Oxidation and Reduction=Cathode
Hope this helps!
