Anode and Cathode
How can you figure out which side of the cell diagram will be the cathode and which will be the anode? Is it only based on the whether the Ecell is negative or positive along, or are there other factors?

Re: Anode and Cathode
If it gets oxidized then it is an anode and if it gets reduced then it is a cathode. I like to think "an ox" and "red cat" when working with half reactions and find it easier to draw my cell diagrams with anode to the left and cathode to the right since it's presented like that in the shorthand notation.

Re: Anode and Cathode
In a cell diagram, the cathode was always on the right side of the double bar divider thing.

Re: Anode and Cathode
Another way to distinguish cathode and anode is to make sure the Ecell comes out to a positive number when you subtract them

Re: Anode and Cathode
Cathode is always on the right side of a cell diagram and anode is always on the left side.

Thank you!!

Re: Anode and Cathode
how do the terms anode and cathode relate to oxidation and reduction. He used the latter pair of terms to define anode and cathode, but can someone explain this further?

Cathode is the reduction reaction and the anode is the oxidation reaction.

Re: Anode and Cathode
To remember what's being oxidized and what's being reduced, it's helpful to think of the mnemonic LEO says GER. (Lose Electrons Oxidation. Gain Electrons Reduction.)

Re: Anode and Cathode
The TA in my discussion said that cathodes are usually on the right and anodes are usually on the left of the salt bridge in a diagram
