Unformatted text preview: 10M), Pb2+(? M) || Pb(NO3)2(0.050 M) | Pb(s) which of the following is the correct expression for Q for the spontaneous overall cell reaction, Pb2+(0.050M) Pb2+(?): Four choices will be given Part III Analysis. For the concentration cell, Pb(s) | PbSO4(s), NH4+ (3.0M), SO42(1.50M), NO3- (0.10M), Pb2+(? M) || Pb(NO3)2(0.050 M) | Pb(s), Ecell = (0.0257/2)lnQprevious question, what is the expression for x in terms of Ecell? 4 choices will be given. Part III Analysis. Using your measured cell potential for Pb(s) | PbSO4(s), NH4+ (3.0M), SO42-(1.50M), NO3- (0.10M), Pb2+(? M) || Pb(NO3)2(0.050 M) | Pb(s) in your expression for x, calculate the molarity of Pb2+ in the anode compartment. Part III Analysis. Which of the following is the correct solubility product expression, Ksp, for PbSO4? Five choices will be given Part III Analysis. Using the expression, Ksp = [Pb2+][SO42-], the concentration of sulfate in the anode compartment, and determined value Pb2+ concentration in the anode compartment, calculate Ksp. Please enter your molarity in decimal form only. Do not use scientific notation. 22 EDTA T...
