Answer:- [tex]NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)[/tex]
Explanations:- The solution we have is a buffer solution and we know that a buffer solution resists a change in its pH if a strong acid or base is added to it.
Here, the buffer solution we have is of a weak base and it's conjugate acid. So, a strong acid(nitric acid) is added to this buffer then it reacts with the base present in the buffer so that the acid could be neutralized. This is called buffer action.
The net ionic equation is written as:
[tex]NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)[/tex]
Note that [tex]HNO_3[/tex] is a strong acid and nitrate ion is the spectator ion so it is not included in the net ionic equation.
NH₃ + H⁺ → NH₄⁺ is the net ionic equation for the reaction that occurs when a few drops of nitric acid are added to the buffer.
What is net ionic equation?
When from the molecular balanced equation we write the ionic equation and remove the spectator ions, then we get the net ionic equation.
In the given question we have a buffer solution of weak base and its conjugate acid, and we add strong nitric acid in it which reacts with the base to maintain the pH of the solution. So, total ionic equation is written as:
NH₄⁺ + Cl⁻ + H⁺ + NO₃⁻ + NH₃ → NH₄⁺ + Cl⁻ +NO₃⁻ + NH₄⁺
Spectators ions are those which remain same on both the side, so the net ionic equation will be:
NH₃ + H⁺ → NH₄⁺
Hence, net ionic equation is NH₃ + H⁺ → NH₄⁺.
