To convert the electrode potential from the standard hydrogen electrode (SHE) scale to the saturated calomel electrode (SCE) scale, we need to use the following relationship:
Given that the electrode potential is
vs.
, we first need to find the electrode potential on the SHE scale. The standard hydrogen electrode has a potential of 0.000 V by definition.Since the potential of the copper electrode is given as
vs.
, we can assume that the potential of the hydrogen electrode is 0.000 V:
Now, we can convert this to the SCE scale using the relationship:
Therefore, the electrode potential on the SCE scale is
.
