Two solutions are separated by a semipermeable membrane, Ask an Expert

Academics

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).

What is the value for the sodium equilibrium potential in this condition? (show how you calculate this)

In one sentence, describe why it has a positive or negative value.

What would be the value of the chloride equilibrium potential? (show how you calculate this)

What is the voltage of side B relative to side A?

Does the chloride equilibrium potential contribute significantly to the voltage actually being measured by the investigator? Why or why not (one sentence)?
