Q. 13 D
Identify the substance oxidized reduced, oxidizing agent and a reducing agent for each of the following reactions:
N2H4 (l) + 2H2O2 (l) → N2(g) + 4H2O(l)
Oxidised substance:- N2H4
Reduced Substance:- H2O2
Reducing agent:- N2H4
Oxidising agent:- H2O2
Explanation:- Oxidising agent is a reagent which can increase the O.N. of an element in a given substance.
H2O2 helps nitrogen to increase its Oxidation state.
The reduced substance is a reagent whose oxidation state has been decreased.
Here in this case, O in H2O2 has -1 oxidation state and the O.N. is reduced to -2 as oxygen in the product side is present in -2 O.N.
The oxidised substance is a reagent whose oxidation state has been decreased.
N in N2H4 is present in -2 O.N which is increased to zero in the product side where N is present as N2 (its elemental form)
Reducing Agent is a reagent which lowers the oxidation number of an element in a given substance.
N2H4 helps oxygen to decrease its O.N.
