Anode & cathode

Postby AlyssaYeh_1B » Sun Feb 23, 2020 1:14 pm

Does anyone have any tips to memorize that the anode is where oxidation occurs, and the cathode is where reduction occurs?

I kind think of it as the word cathode has a "t" in it, which looks like a "+" sign so we know it gains electrons (which is what happens in reduction), and then anode is the opposite. Hope this helps.

Additionally, I'd say that it might help to know that anions flow to the anode to balance the charge and cations flow to the cathode to balance the charge as well. :D

Hi Alyssa,

The way I memorize it is the same way I memorize cations (+) and anions (-). The cathode is associated with a positive sign because it is where reduction occurs; reduction is the gain of electrons. The anode is associate with a negative sign because it is where oxidation occurs; oxidation is the loss of electrons. By associating cathodes and anodes with these signs, I can remember which is responsible for each part of a redox reaction. I hope this helps!

My TA mentioned how oxidation is related to the anode because both started with vowels while the cathode is with reduction because both started with consonants.
