HNO2 + H2O ⇆ H3O+  + NO2- 

A) conjugate base of HNO2

B) conjugate acid of HNO2

C) conjugate acid of H2O. 

D) conjugate base of H2O.

Solutions

Expert Solution

Answer :- C) conjugate acid of H2O

Explanation :-

Conjugate acid :-

A conjugate acid is formed when a base reacts. It is the base that has received the H+ from the acid and donates the OH- ion in reaction.

Conjugate base :–

A conjugate base is formed when an acid reacts. It is the acid that gave the base the H+ ion and receives the OH- ion in reaction.

In this reaction HNO2 gives H+ ion that means HNO2 reacts as acid and H2O received H+ ion so reacts as base.

H2O which is base receive H+ ion and mades its conjugate acid H3O+.

So H3O+ is Conjugate acid of H2O.
