Nernst equation

Post by Neon »

Hello,

I would like to ask you a question about Nernst equation. So this is the correct notation of Nernst's equation if I want to calculate the pH measured with a pH meter?:
\( E= E0 + (2,3RT)/(nF) * pH \)
So does a pH meter use this equation to calculate pH?




Thank you in advance!

Yes it does. The measurment is a difference between a known calibrated solution inside the probe and the unknown value of the sample.
