(a)
Interpretation: The oxidized and reduced species in the reaction,
Concept Introduction: The zero, positive or negative numbers that are assigned to an atom for indicating its degree of oxidation and reduction is the oxidation number. This number indicates the number of electrons that are either gained or lost during the bond formation in a chemical compound.
(a)
Answer to Problem 19LC
The chemical species that undergo oxidation is
Explanation of Solution
The completion of
The one in which the oxidation number is found to be decreased is said to be reduced. Since reduction involves the gain of electrons. While the one in which the oxidation number is found to be increased is said to be oxidized. Since oxidation involves the loss of electrons.
In the reaction,
The oxidation number of sodium,
The oxidation number of chlorine,
(b)
Interpretation: The oxidized and reduced species in the reaction,
Concept Introduction: The zero, positive or negative numbers that are assigned to an atom for indicating its degree of oxidation and reduction is the oxidation number. This number indicates the number of electrons that are either gained or lost during the bond formation in a chemical compound.
(b)
Answer to Problem 19LC
The chemical species that undergo oxidation is
Explanation of Solution
The completion of chemical reactions results in a change in the oxidation number of chemical compounds. From the change in oxidation number values, the chemical species that have undergone oxidation and reduction can be easily found.
The one in which the oxidation number is found to be decreased is said to be reduced. Since reduction involves the gain of electrons. While the one in which the oxidation number is found to be increased is said to be oxidized. Since oxidation involves the loss of electrons.
In the reaction,
The oxidation number of Iodine,
The oxidation number of nitrogen in
(c)
Interpretation: The oxidized and reduced species in the reaction,
Concept Introduction: The zero, positive or negative numbers that are assigned to an atom for indicating its degree of oxidation and reduction is the oxidation number. This number indicates the number of electrons that are either gained or lost during the bond formation in a chemical compound.
(c)
Answer to Problem 19LC
The chemical species that undergo oxidation is sulfur and that undergoes reduction is nitrogen in the given reaction.
Explanation of Solution
The completion of chemical reactions results in a change in the oxidation number of chemical compounds. From the change in oxidation number values, the chemical species that have undergone oxidation and reduction can be easily found.
The one in which the oxidation number is found to be decreased is said to be reduced. Since reduction involves the gain of electrons. While the one in which the oxidation number is found to be increased is said to be oxidized. Since oxidation involves the loss of electrons.
In the reaction,
The oxidation number of sulfur presents in
The oxidation number of nitrogen in

In the reaction,
The oxidation number of lead,
The oxidation number of lead,
Therefore, the oxidized and reduced species are the same in this case. The reaction is disproportionate.
