Question

Calculate the standard electrode potential of the half-cell reaction Ag+ + e- → Ag, given that the standard reduction potential of Ag+ is 0.80 V.

Answer 1

The standard electrode potential of a half-cell reaction is the same as its standard reduction potential when the reaction is written as a reduction  gain of electrons . In this case, the half-cell reaction is already written as a reduction:Ag+ + e-  AgSince the standard reduction potential of Ag+ is given as 0.80 V, the standard electrode potential of this half-cell reaction is also 0.80 V.
