(a)
Interpretation:
The oxidation states to all the elements in the given reaction should be assigned along with identify the reactant which is oxidized and reduced and also identify the oxidizing agent and reducing agent in the given reaction.
Concept Introduction:
A redox reaction is a
Oxidation state or oxidation number of an atom is defined as the positive or the negative charge that an atom would possess if it is present as ions in the given compound. In such type of reaction, the oxidation state of the atom undergoing oxidation will increase which depends upon the number of electrons lost by a particular atom.
Reduction of a chemical species refers to the gain of electrons by the chemical species which results in decrease in oxidation state of that atom.
A reducing agent is one which loses its electrons for the reduction of other chemical species which are undergoing redox reactions. In other words we can say that a reducing agent in a chemical reaction is the species which itself gets oxidized by loss of its electrons.
On the other hand an oxidizing agent is a chemical species which has the ability to oxidize other substances which are present in a chemical reaction. It acts by gaining electrons in a chemical reaction, thus itself gets reduced.
(b)
Interpretation:
The oxidation states to all the elements in the given reaction should be assigned along with identify the reactant which is oxidized and reduced and also identify the oxidizing agent and reducing agent in the given reaction.
Concept Introduction:
A redox reaction is a chemical reaction in which oxidation and reduction reactions takes place simultaneously. In such type of reaction one of the chemical species is getting oxidized while the other species gets reduced at the same time.
