### Nernst Equation and pH

How can we use the Nernst Equation to calculate pH? Does it have to do something with ion-selective electrodes?

### Re: Nernst Equation and pH

You can use Nernst Equation to find Q or K if it is at equilibrium. Then you can solve for [H+] if you are given other concentrations.

### Re: Nernst Equation and pH

Use Nernst to find K, and then solve the equilibrium expression for concentration and then pH.

Return to “Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH)”
