Nernst equation: Learn how to use

Learn how to use the Nernst equation to calculate electrochemical cell potential at any temperature, pressure, and concentration. See the derivation, an example problem, and the limitations of the equation . The Nernst Equation enables the determination of cell potential under non-standard conditions. It relates the measured cell potential to the reaction quotient and allows the accurate determination of equilibrium constants (including solubility constants). Learn how to use the Nernst Equation to calculate cell potential and equilibrium constants under non-standard conditions. The web page explains the derivation, formula, and examples of the Nernst Equation with Zn-Cu redox reaction. What is the Nernst Equation ? The Nernst equation relates the electrode potential of a cell to the standard electrode potential, temperature, the number of electrons involved in the redox reaction, and the concentrations (or pressures) of reactants and products.
