cathodes and anode location

Postby Jennifer Fimbres » Sun Mar 17, 2024 11:41 pm

when given the system and determining which is the cathode and which is the electrode, will they always be anode on the left and cathode on the right or is that just how its been in a lot of our examples?

For uniformity and simplicity of interpretation, electrochemical cells typically have an anode on the left and a cathode on the right. However, it is not an inherent principle of electrochemistry and may differ based on the unique context or convention utilized in a given system or literature. I hope my answer will be of some help!

To determine the anode vs the cathode one must ensure which of the 1/2 reactions is reduced or oxidized. If the 1/2 reaction is oxidized then it is anode, if the 1/2 reaction is reduced then it indicates the cathode.

In cell diagrams, anodes are placed on the left and cathodes on the right, two vertical lines between the half-cells in order to represent a salt bridge that divides the two.

In cell diagrams this is you know the anodes on the left and the cathodes on the right. However, you don't know this with the general reaction.
