What is the voltage of side b relative to side a | Homework Help

Two solutions are separated by a semipermeable membrane that is permeable to sodium but not chloride or potassium ions. Solution A on the left contains a solution that is 100 mM NaCl, while Solution B on the right has a concentration of sodium chloride of 1 mM.

There is an electrode in both solutions, and a comparative assessment of voltages between the two compartments is being made. The investigator doing the study decides to call side A ground potential (or, in other words, defines it as 0).
