Cell potential is affected by factors that influence the voltage of the cathode and anode in an electrochemical cell.
Based on the provided reference, the following factors affect cell potential:
-
Cathode Voltage: Increasing the voltage of the cathode increases the overall cell potential. The reference states, "When you take the difference in voltage between the cathode and anode, you will see that the cell potential increases because the voltage of the cathode increased."
-
Anode Concentration: Increasing the concentration of the anode's reactive ions increases the cell potential of the anode. According to the reference, "increasing the concentration of Al would increase the cell potential of the anode because there are more ions available for oxidation." For example, a higher concentration of Al3+ ions will increase the anode's oxidation potential.
In summary, changes in the voltage of the cathode, as well as alterations in the concentration of ions at the anode, directly influence the cell potential.
