Concept explainers
(a)
Interpretation:
The overall cell reaction for the alkaline Leclanche cell should be written.
Concept introduction:
A superior form of the Leclanche cell is the alkaline cell. It uses NaOH or KOH instead of NH4Cl as the electrolyte.
(b)
Interpretation:
The E0cell for the cell reaction should be determined.
Concept introduction:
In an
If oxidation takes place on an electrode, that electrode is called anode. The species in that electrode remove electrons and itself gets oxidized.
If reduction takes place on an electrode, that electrode is called cathode. The species in that electrode absorbs electrons and itself gets reduced.
The electrode potential of cell can be calculated as follows:
