(a)
Interpretation:
If the given half reaction shows oxidation or reduction should be determined.
Concept Introduction:
In a
When a species loss electron/s, its oxidation state increases thus, increase in oxidation state is oxidation similarly, when a species gains electron/s, its oxidation state decreases thus, decrease in oxidation state is reduction.
In a cell, the oxidation takes place at anode electrode and reduction takes place at cathode electrode.
(b)
Interpretation:
The substance that oxidized or reduced should be identified.
Concept Introduction:
In a chemical reaction, oxidation is defined as loss of electron/s and reduction is defined as gain of electron/s.
When a species loss electron/s, its oxidation state increases thus, increase in oxidation state is oxidation similarly, when a species gains electron/s, its oxidation state decreases thus, decrease in oxidation state is reduction.
In a cell, the oxidation takes place at anode electrode and reduction takes place at cathode electrode.
(c)
Interpretation:
The electrode at which the given half reaction takes place should be determined.
