Concentration cell

Postby Carissa Young 1K » Wed Mar 13, 2019 10:48 pm

In a concentration cell, why does reduction take place on the electrode with a higher concentration? (w/same components)

Due to the Nernst equation, Ecell > 0 when Q is < 0, so the concentration of the cathode will be greater than the concentration of the anode because Q = concentration of left (anode) divided by concentration of right (cathode).

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