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
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...
