The following cell was found to have a potential of 0.124 V: Ag l AgCl(sat'd) ll Cu2+(0.00325 M) l membrane electrode for Cu2+ When the solution of known copper activity was replaced with an unknown solution, the potential was found to be 0.086 V. Neglecting junction potential, what was the molar concentration of copper in this unknown solution?
