Galvanic Cells

Postby Theodore_Herring_1A » Sat Mar 16, 2019 9:29 pm

How do you know which reaction is the cathode and which is the anode in a galvanic cell?

The cathode is where the reduction reaction occurs (usually on the right side) whereas the anode is where the oxidation reaction occurs (usually on the left.

The anode is the species giving up an electron (going from a lower to higher positive charge) and the cathode is the one accepting the electron (going from a higher to lower positive charge).

Usually the one with the more positive E value, the reduction potential, the greater chance that it is going to be reduced, and thus will be the cathode. The one with the lower E value will most likely be the one oxidized, being the anode.

The anode is the one being oxidized, and the cathode is the one being reduced (an ox, red cat).
