Answer 2

Answer:

NO³⁻ is the anion which gives out white fumes in the reaction given.

Explanation:

Reaction:

• When HNO₃ is added to Zn and NaOH and a glass rod dipped in conc. HCl is brought near it, the visible white fumes are of the anion NO³⁻.
• The given reaction is:

        Zn + NaOH + HNO³ + HCl → ZnCl + NaNO₃ + H2O

In the above reaction, the white fumes are formed due to the evolution of NaNO₃ in which the cation and anion are Na⁺ and NO³⁻ respectively.
