Question
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). Using the Nernst equation,
which is also shown below and described in
your textbook, what is the equilibrium
