(Spontaneity of Redox Reactions â 13 points) For this entire question, assume T is constant at 300. K, H2(g) is maintained at standard state conditions, R = 8.314 J mol-1 K-1, F = 96485C mol-1, and all activity coefficients are equal to 1.0. a. (8 points) You have four beakers, each one containing 1.0 L of an aqueous solution buffered to a pH = 1.0 (i.e [H3O+] = [H+] = 0.1M) and with 1 M of dissolved metal ions in each. You place a bar of silver (Ag) in beaker #1 which contains 1M Ag+, a bar of copper in beaker #2 which contains 1M Cu2+, a bar of lead in beaker #3 which contains 1M Pb2+, and a bar of zinc in beaker #4 which contains 1M Zn2+. Using the table of standard reduction potentials provided to the right, identify and report which beaker(s) a spontaneous dissolution (M(s) ? Mn+(aq); where âMâ represents the solid metal and âMn+â represents the metal cations) of some portion of the metal bar would or would not occur â provide an answer for each of the four beakers and show some justification for your answer to receive any credit

b. (5 points) You now prepare a fifth beaker also containing 1.0 L of an aqueous solution buffered to a pH = 1.0 (i.e [H3O+] = [H+] = 0.1M). To this beaker you then add a bar of pure copper (Cu(s)). Will there be a spontaneous dissolution of some portion of the copper bar in order to the system to establishes equilibrium? If yes, utilize the provided table of standard reduction potentials and the Nernst equation to calculate and report the concentration of Cu2+ ions in solution once the system attains equilibrium. Note : this system is different than Part A above in which beaker #2 initially had 1M of Cu2+ ions present; in this beaker #5 there is initially zero Cu2+ ions. Report your final answer with 1 significant digit.
