Cell Potential Calculator

The Cell Potential Calculator is a useful device that tells us if a chemical reaction with electricity (electrochemical response) will appear and in which course. It’s beneficial for predicting these reactions whilst things like awareness and temperature are not regular.

Cell Potential

Cell ability often denoted as Ecell, is a measure of the electric capacity difference between two half-of-cells in an electrochemical mobile.

It represents the riding force for electrons to float from the anode to the cathode, generating an electric present day.

The mobile capability is a key parameter in understanding the spontaneity and direction of electrochemical reactions.

Cell Potential Equation

The standard representation of cell potential is given by the formula.



  • Ecell​ is the cell potential.
  • Ecathode​ is the standard reduction potential at the cathode.
  • Eanode​ is the standard reduction potential at the anode.

A positive cell potential indicates a spontaneous reaction, meaning the electrochemical cell can produce electrical energy. On the other hand, a negative cell potential suggests a non-spontaneous reaction.

Cell Potential Formula

The formula provided is for calculating the cellular ability (Ec) of an electrochemical cellular. Here’s the method.



Ec​ is the cellular potential.

Eca​ is the cathode potential.

Ea​ is the anode capability.

To discover the entire cell potential, you subtract the anode potential (Ea​) from the cathode capacity (Eca​). The resulting cellular potential (Ec​) offers facts about the potential of the electrochemical cell to generate an electric-powered cutting-edge. Positive values of Ec​ imply a spontaneous reaction, while bad values imply a non-spontaneous response.

How to Calculate Cell Potential

To locate Cell Potential, we want to Potentially observe these steps.

Open the Cell Potential Calculator

Open the Page containing the Cell Potential Calculator.

Enter Cathode and Anode Potentials

Find the input fields categorized “Cathode Potential (E_cathode)” and “Anode Potential (E_anode)” on the calculator interface.

Enter the values for the cathode and anode potentials. Make sure to enter valid numerical values.

Click “Calculate Cell Potential”

After entering the cathode and anode potentials, click on the “Calculate Cell Potential” button on the calculator.

View the Result

The calculator will technique the entered values and display the calculated cell ability.

Look for the result displayed below the button, including “Cell Potential (E_cell): X.XX V.”

Interpret the Result

If the cellular ability is wonderful, it shows a spontaneous response, and the electrochemical mobile can produce electric power.

If the cell capacity is poor, the reaction is non-spontaneous under standard conditions.


For instance, in case you enter a cathode ability of zero.80 V and an anode capability of -zero.20 V, and then click on “Calculate Cell Potential,” the calculator may show “Cell Potential (E_cell): 1.00 V.”

This would imply that, below well-known conditions, the electrochemical cell has a wonderful mobile capacity of 1.00 V, indicating a spontaneous reaction capable of generating electric strength.
