Consider a Nernstian surface with surface charge determined by the potential-determining ion A. Assume NaCl is also in solution as an indifferent electrolyte, and the concentration of NaCl is much larger than that of other ions. Assume ideal solution theory, and consider the case in which the pzc is at pA = 6. Derive a relation for q00 wall as a function of [A] and the bulk concentration of NaCl.
