Concept explainers
(a)
Interpretation: The given each reaction as an oxidation half-reaction or reduction half-reaction has to be explained.
Concept introduction:
The cell reaction can be represented as two half-reactions with the number of transferred electrons. They are as follows:
- • Oxidation half-reaction.
- • Reduction half-reaction.
Oxidation half-reaction: The oxidation half-reaction is the part of a redox reaction that shows only for the oxidized species with the transferred electrons and its oxidation state increases with the loss of electrons.
Reduction half-reaction: The reduction half-reaction is also the part of a redox reaction (the counter part of oxidation half-reaction) that shows only for the reduced species with the transferred electrons and its oxidation state decreases with the gain of electrons.
Oxidation: Losing electrons, increasing oxidation number.
Reduction: Gaining electron, decreasing oxidation number.
