Question
The standard electrode potentials given in your Data Booklet are reported using the standard hydrogen half-cell as the reference half-cell.
If the standard reference half-cell used to construct a table of electrode potentials was Zn²+ (aq) + 2e" - Zn(s), the standard electrode potential for Fe2(aq) + 2e → Fe(s) would be
Select one:
O +0.31V
O -0.45V
O +0.45V
O -0.31V
If the standard reference half-cell used to construct a table of electrode potentials was Zn²+ (aq) + 2e - Zn(s), the cell potential for a Fe(s) | Fe²+ (aq) || Cu²+ (aq) | Cu(s) cell would be
Select one:
O -0.79V
O -1.55V
+1.55V
+0.79V
The cost of producing a Cu(s) | Cu²+ (aq) || Au³+ (aq) | Au(s) cell can be reduced without affecting the cell voltage. Simply replace the
with a less expensive
