About the Nernst Equation
The Nernst equation relates electrode potential to the standard potential and the concentrations of chemical species involved. It shows how potential changes from standard conditions.
At 25°C: E = E° - (0.0592/n)log₁₀(Q)
A 10-fold change in concentration ratio changes the potential by ~59.2/n mV.
