Current Question (ID: 8443)

Question:

$\text{The species that can act as Brønsted acids as well as bases is/are:}$

Options:

1. $\text{H}_2\text{O}$
2. $\text{HCO}_3^-, \text{HSO}_4^-$
3. $\text{NH}_3$
4. $\text{All of the above}$

Solution:

$\textbf{Hint: } \text{Brønsted acids and bases are those species which gives proton } (\text{H}^+) \text{ and accepts proton respectively.}$ $\text{All the species can act as a brønsted acid and brønsted base.}$ $\text{The reaction is as follows:}$ $\text{H}_2\text{O} + \text{NH}_3 \leftrightarrow \text{NH}_4^+ + \text{OH}^-$ $\text{H}_2\text{O} + \text{H}^+ \rightarrow \text{H}_3\text{O}^+$ $\text{HCO}_3^- \rightarrow \text{CO}_3^{2-} + \text{H}^+$ $\text{HCO}_3^- + \text{H}^+ \rightarrow \text{H}_2\text{CO}_3$ $\text{HSO}_4^- + \text{H}^+ \rightarrow \text{H}_2\text{SO}_4$ $\text{HSO}_4^- \rightarrow \text{SO}_4^{2-} + \text{H}^+$ $\text{NH}_3 + \text{H}^+ \rightarrow \text{NH}_4^+$
