Anode and Cathode placement in Galvanic/Voltaic Cells

Postby Erika Gonzalez 1F » Sun Feb 05, 2017 8:00 pm

For a Galvanic cell, does the anode need to be on the left side and the cathode on the right at all times? Or can it be vise versa? And can someone elaborate more on the cell potential? I just know that it is the maximum potential/voltage of the cell.

No, in the physical Galvanic cell, placement of the electrodes do not matter. It is just that the convention expressed in the textbook where the electron flow is from left to right, that the oxidized species is on the left and reduced species is on the right in writing the cell diagram.

The cell potential is the maximum potential that can be converted from the system to do work, like powering a lamp.
These values were measured in relation to a "0," the standard hydrogen electrode.

The cell potential describes how much work can be produced from the energy converted from the system. It is compared to the standard hydrogen electrode because this electrode serves as a reference point when calculating/comparing data.
