Passage / Comprehension

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 reaction can be used to produce $NO_{2}$ ?

Options:

Answer:

Solution:

The reaction of zinc (Zn) with concentrated nitric acid (HNO₃) produces nitrogen dioxide (NO₂).

$Zn (s) + 4 HN O_{3} (co n c .) \to Zn (N O_{3})_{2} (a q) + 2 N O_{2} (g) + 2 H_{2} O (l)$

This is a redox reaction where nitric acid acts as an oxidizing agent.
