Question

The reaction of zinc with dilute and concentrated nitric acid, respectively, produces ______.

पर्याय

• N₂O and NO₂

• NO₂ and NO

• NO and N₂O

• NO₂ and N₂O

Answer 1

The reaction of zinc with dilute and concentrated nitric acid, respectively, produces N₂O and NO₂.

Explanation:

When zinc reacts with dilute nitric acid, nitrous oxide (N₂O) is produced as the nitrogen oxide gas. On the other hand, with concentrated nitric acid, nitrogen dioxide (NO₂) is formed. This happens because the concentration of nitric acid determines the reduction product formed in the reaction with zinc. Thus, zinc with dilute nitric acid produces N₂O, and with concentrated nitric acid produces NO₂.
