### Manipulating Cathode or Anode Concentration

Can someone explain the effects of manipulating the cathode and anode in the Ln Q portion of the nernst equation?

### Re: Manipulating Cathode or Anode Concentration

In the nernst equation: E = Eo -(RT/nF)ln Q
since the anode foes on top and cathode foes on the bottom for Q, as the reaction progresses, the concentration of the left (oxidation) anode as the solid electrode dissolves while the concentration in the right (reduction) cathode decreases as the electrode in that compartment gains mass

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