### Cell Diagram

For cell diagrams, theoretically I know that the reaction on the right is the cathode only if the cell potential is positive but for the purposes of the class, if the cell potential is not given then should one assume the cathode is the reaction on the right?

Yea I think that is an assumption that we make, but they will usually specify regardless.

Yes. I find it useful to remember that Reduction occurs on the Right in the Cathode (all consonants, two Rs) while Oxidation occurs in the Anode (vowels) on the left.

Generally, reduction occurs in the cathode and oxidation in the anode.

### Re: Cell Diagram

reduction is in the cathode while oxidation occurs in the anode. Also, the cathode is typically on the right

### Re: Cell Diagram

If the cell potential is not given, then assume the right is the cathode and the left is the anode. You might have to look up the cell potentials and add them up to give a positive standard cell potential to determine the anode and cathode.

### Re: Cell Diagram

I believe we can always assume the cathode is on the right side.

### Re: Cell Diagram

Anode should be on the left, cathode should be on the right in most diagrams.

I think it is safe to assume that the anode will be on the left while the cathode will be on the right.

### Re: Cell Diagram

If cell potential is not given, the oxidation half-reaction should be on the left/anode, while the reduction half-reaction should be on the right/cathode. You should look at how electrons are transferred to verify though.

### Re: Cell Diagram

Yes. Reduction occurs at the cathode and it is placed on the right of the cell diagram while oxidation occurs at the anode and that is placed on the left of the cell diagram.

### Re: Cell Diagram

I think it would be okay for you to assume that the cathode is one the right and the anode is on the left.

Yes, if the potentials are not given you can assume the cathode is on the right and the anode is on the left.

### Re: Cell Diagram

I encountered a question once where the cathode was on the left and the anode was on the right, opposite of the convention of typical cell diagrams. So while it's generally a safe assumption that the cathode is on the right and the anode is on the left, I would still verify this by checking where the electrons are going.

### Re: Cell Diagram

I am pretty sure cathode is always on right and anode is always on left. that is how it is always shown for problems. but i guess you can make cathode on left if you make electrons flowing towards left.
