APFIVE Concentration Effects on Cell Potential
Consider a galvanic cell composed of a zinc electrode in a 1.0 M ZnSO₄ solution and a copper electrode in a 1.0 M CuSO₄ solution. If the concentration of Cu²⁺ ions is increased to 2.0 M, how will this affect the cell potential, and why can’t Le Châtelier’s principle be applied to predict this change?
A
Cell potential remains unchanged; system at equilibrium
B
Cell potential increases; system not at equilibrium
C
Cell potential decreases; system not at equilibrium
D
Cell potential decreases; Le Châtelier’s principle applies
