Here’s a explanation:
The cell potential is the voltage produced by an electrochemical cell.
- To calculate it, you look at the tendency of the two electrodes to gain or lose electrons.
- The cathode is where reduction happens (gains electrons), and the anode is where oxidation happens (loses electrons).
- The cell potential is basically the difference in “electron-pulling power” between the cathode and anode.
- Positive voltage means the reaction happens on its own (spontaneous), and negative voltage means it does not.
In short: Cell potential tells you how much electricity a cell can produce, based on the difference in tendencies of the two electrodes.
