What is the Nernst Equation Calculator?

The Nernst Equation Calculator helps students and chemistry learners calculate the electrode potential of a half-cell under non-standard conditions. By entering the standard electrode potential, number of electrons transferred, and the concentrations of reduced and oxidized species, the calculator determines the actual potential using the Nernst equation. This is essential for studying electrochemistry, redox reactions, and predicting the direction of electron flow.

How to Use:

1. Enter Standard Electrode Potential (E⁰): Type the standard potential in volts (V).
2. Enter Number of Electrons (n): Input the number of electrons involved in the half-reaction.
3. Enter Concentration of Reduced Species ([Red]): Provide the molar concentration of the reduced form.
4. Enter Concentration of Oxidized Species ([Ox]): Provide the molar concentration of the oxidized form.
5. Click “Calculate”: The calculator applies the Nernst equation to determine the electrode potential.
6. Review Result: The output shows the actual electrode potential in volts (V), indicating how the cell behaves under given concentrations.
