Current Question (ID: 8550)

Question:

$\text{The dissociation of } \text{NH}_4\text{OH can be suppressed by the addition of}$

Options:

1. $\text{NH}_4\text{Cl}$
2. $\text{NH}_4\text{NO}_3$
3. $\text{NaOH}$
4. $\text{All of the above}$

Solution:

\text{Hint: Use concept of common ion effect} \text{NH}_4\text{OH is a weak base. The dissociation reaction of NH}_4\text{OH is as follows:} \text{NH}_4\text{OH } \rightleftharpoons \text{NH}_4^{+} + \text{OH}^{-} \text{Hence, any substance which contains OH}^{-} \text{ ion or NH}_4^{+} \text{ when added to NH}_4\text{OH solution then due to common ion effect the dissociation of NH}_4\text{OH decreases.} \text{Here, option 4th is the correct answer.}
