Question
Convert the following voltages. Assume the silver-silver chloride and calomel reference electrodes are saturated with KCI, giving cell potentials of +0.197 V and +0.241, respectively. If an electrode has a potential of 0.381 V with respect to a standard hydrogen electrode (S.H.E.), what is the potential with respect to a silver-silver chloride electrode? Number If an electrode has a potential of -0.093 V with respect to a silver-silver chloride electrode, what is the potential with respect to a S.H.E.? Number If an electrode has a potential of -0.158 V with respect to a saturated calomel electrode (S.C.E.), what is the potential with respect to a S.H.E.? Number If an electrode has a potential of 0.036 V with respect to a silver-silver chloride electrode, what is the potential with respect to a S.C.E.? If an electrode has a potential of-0.026 V with respect to a S.C.E., what is the potential with respect to a sliver-silver chloride electrode? NumberExplanation / Answer
a.) 0.983V-0.197V=0.786V --> potential of cell compared to S.H.E. - conversion factor from S.H.E. to Ag-Ag
b.)-0.044V+0.197V=0.153V -->potential of cell compared to Ag-Ag + conversion factor from Ag-Ag to S.H.E.
c.)-0.087V+0.241V=0.154V --> potential of cell compared to S.C.E. + conversion factor from S.C.E. to S.H.E.
d.)0.029V-(0.241V-0.197V)=0.015V --> potential of cell compared to Ag-Ag -(difference of Ag-Ag and S.C.E.)
e.) -0.005V+(0.241V-0.197V)=0.039V --> potential of cell compared to S.C.E.+(difference of S.C.E. and Ag-Ag)
My way may seem confusing, so if you want to prove to yourself, just convert everything to potentials compared to S.H.E. then convert them to what you want to compare them to. What this really boils down to is just conversion of measurements.
Hope this helps!
