This question also uses the same experimental setup as in Questions 1 and 2 and the same modification of the attached figure (Figure 2.5 of your textbook). The modification is that the KCL solutions in the middle panel are replaced with NaCl solutions (1 mM on the left or inside and 10 mM on the right or outside).
