cell diagrams

Postby 205389184 » Sun Mar 01, 2020 7:50 pm

Will the anode always be on the left and the cathode always on the right or does it depend on the compounds involved?

It depends on the half reactions and whether or not that is considered an anode or a cathode reaction as at the anode there is oxidation and at the cathode there is reduction but the main reason anodes are written on the left and cathodes on the right is to stay consistent with the cell diagram notation.

Yes, standard convention is that anode will be on the left and cathode on the right

on page 550 of the book there is an example where the cathode and anode have flipped sides in the diagram. In class I believe Dr. Lavelle said to look at which one is being reduced and which one is being oxidized and that will tell you which one is the anode/cathode.

99% of the time yes, but it is important to not assume this and always look at the half reactions to figure out which electrode is oxidized (anode/loses electrons) and which is reduced (cathode/gains electrons).

For this class I believe so. But always look at the half reactions to be completely sure

I believe that most of the time, the cell will have this layout, but there are instances where it can be the other way around, so it’s important to pay attention to what is being oxidized and what is being reduced in each individual case instead of assuming.

My TA mentioned that Dr. Lavelle will most likely keep it simple with the anode on the left side and cathode on the right side.
