Anode and Cathode position

Postby ShravanPatel2B » Wed Feb 19, 2020 9:34 pm

When doing problems or when we encounter a galvanic cell on our test do we always assume that the anode is on the left and that the cathode is on the right?

It is conventional to put the anode on the left and the cathode on the right. That being said it would be smart to double-check that this is true in a problem or on a test (if possible) by seeing which is being reduced and which is being oxidized.

It is usually written in that order, but I would always double check to see where the oxidation and reduction reactions are placed in correspondence to the left and the right of the galvanic cell.

Dr. Lavelle mentioned that this is the common arrangement, but it should be possible to tell based on other information given which one is the anode and which is the cathode. I wouldn't rely on it always being in this arrangement, though.

I would always double check what is being oxidized and what is being reduced to ensure it is correct.

just to make sure, you can double check to see which side is oxidized/negative (=anode) and which side is reduced/positive (=cathode)
