2. A concentration cell was prepared at 25 C; one cell compartment contained 0.070 M Pb(C2H3O2)2(aq) and was connected by a salt bridge to a compartment containing Pb2(aq) in saturated 0.050 M Na2SO4(aq). The measured voltage is 0.205 V. a. Write the Ksp expression for PbSO4. b. Use the Nerst Equation to solve the value of Q in the concentration cell. c. From the value of Q and the known [Pb 2]high, solve the diluted equilibrium [Pb+2]low. Note: [Pb 2]low is the equilibrium concentration. d. Using the value of diluted [Pb+2]eq and the saturated [SO4 2] determine Ksp.
