Nitric acid reacts with most of the metal (Except Noble metals like gold and platinum) and non metals. Towards its reaction with metals $HNO_{3}$ acts as an acid as well as an oxidising agent.

Which of the following metal produce $N_{2} O$ gas with dilute $HNO_{3}$ ?

Options:

Answer:

Solution:

Zinc (Zn) reacts with dilute nitric acid (HNO₃) to produce nitrous oxide (N₂O) gas. The reaction is:

$4 Z n (s) + 10 H N O_{3} (d i l u t e) \to 4 Z n (N O_{3})_{2} (a q) + N_{2} O (g) + 5 H_{2} O (l)$

Other metals like copper and silver typically produce NO or NO₂ with dilute or concentrated HNO₃, respectively, while lead reacts differently.
