When the anode ion concentration is decreased and/or the cathode ion concentration is increased, both give rise to larger cell potentials. Why? Concentration cells are commonly used to calculate the value of equilibrium constants for various reactions.

What are concentration cells? What is Ɛ in a concentration cell?
What is the driving force for a concentration cell to produce a
voltage? Is the higher or the lower ion concentration solution
present at the anode? When the anode ion concentration is
decreased and/or the cathode ion concentration is increased, both
give rise to larger cell potentials. Why? Concentration cells are
commonly used to calculate the value of equilibrium constants for various reactions. For example, the silver concentration cell can be used to determine the Ksp value for AgCl(s). To do so, NaCl is added to the anode compartment until no more precipitate forms. The Cl^- in solution is then determined somehow. What happens to Ɛ_cell
when NaCl is added to the anode compartment? To calculate the Ksp value, Ag⁺ must be calculated. Given the value of Ɛ_cell how is Ag⁺ determined at the anode?
