At 298 K, the solubility product constant for PbC 2 O 4 is 8.5 10 -10
Question:
At 298 K, the solubility product constant for PbC2O4
is 8.5 × 10-10, and the standard reduction potential of the Pb2+(aq) to Pb(s) is -0.126 V.
(a) Find the standard potential of the half-reaction
The desired half-reaction is the sum of the equations for the solubility product and the reduction of Pb2+. Find ΔG° for these two reactions and add them to find ΔG° for their sum. Convert the ΔG° to the potential of the desired half-reaction.)
(b) Calculate the potential of the Pb/PbC2O4 electrode in a 0.025 M solution of Na2C2O4.
