Q. What are the values of C and F in systems consisting of solid AgCl in equilibrium with an aqueous phase containing H2O, AgC(aq), Cl(aq), NaC(aq), and NO3 (aq) prepared in the following ways? Give examples of intensive variables that could be varied independently.
(a) The system is prepared by equilibrating excess solid AgCl with an aqueous solution of NaNO3.
(b) The system is prepared by mixing aqueous solutions of AgNO3 and NaCl in arbitrary proportions; some solid AgCl forms by precipitation.
