(a) If you were to construct a concentration cell in which one half-cell contains 1.0 m CrCl₃(aq) and the other half-cell contains 0.0010 m CrCl₃(aq), and both electrodes were chromium, at which electrode would reduction be spontaneous? How will each of the following changes affect the cell potential? Justify your answers.

(b) Adding 100 mL pure water to the anode compartment.

(c) Adding 100 mL of 1.0 m NaOH(aq) to the cathode compartment (Cr(OH)₃ is insoluble).

(d) Increasing the mass of the chromium electrode in the anode compartment.
