Question
What is the CORRECT expression of potential (versus SHE) at the equivalence point
(EEP) for the titration of ceric ion (Ce4+) with plumbous ion (Pb2+)?
Ce4+ +e- -->
Ce3+
Pb4+ + 2e-
Pb2+
-->
O EEP = [(E°Ce + 2E°pb)/3] – (0.0592/3) log ([Ce³"][Pb4+/[Ce++][Pb2+])
O EEP = (E°Ce + E°pb)/2
O EEP = (E°Ce + 2E°pb)/3
O EEP = (E°Ce + E°pb) – 0.0592 log ([Ce³+][Pb2+]/[Ce4+][Pb4+j)
