Which of the following is not an amphoteric substance?
- A \(\mathrm{H}_{2} \mathrm{O}\)
- B \(\mathrm{NH}_{3}\)
- C \(\mathrm{HNO}_{3}\)
- D \(\mathrm{HCO}_{3}^{-}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{HNO}_{3}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{HNO}_{3}\) is not an amphoteric substance as, it behave only as acid. It can only donate \(\mathrm{H}^{+}\)ions. While, substance like \(\mathrm{HCO}_{3}^{-}, \mathrm{H}_{2} \mathrm{O}\), and \(\mathrm{NH}_{3}\) can act as both donor and acceptor to…
