(a)
Interpretation:
The equations relevant to the different operations of a Leclanche cell should be combined to a single overall reaction.
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.
(b)
Interpretation:
The value of E for each half cell reaction should be estimated.
Concept introduction:
In an electrochemical cell, there are two electrodes that can be observed.
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:
