Question

Chemical nature of the nitrogen oxide compound obtained from a reaction of concentrated nitric acid and P₄O₁₀ (in 4 : 1 ratio) is ______.

Options

• acidic

• amphoteric

• neutral

• basic

Answer 1

Chemical nature of the nitrogen oxide compound obtained from a reaction of concentrated nitric acid and P₄O₁₀ (in 4 : 1 ratio) is acidic.

Explanation:

The reaction between conc. HNO₃ with P₄O₁₀ in the ratio of 4 : 1 gives dinitrogen peroxide (N₂O₅)·

\[\ce{4HNO3 + P4O10 -> 2N2O5 + 4HPO3}\]

When N₂O₅ is mixed with water, it produces an aqueous, acidic solution. It can react directly with bases to produce salts.

Therefore, the nitrogen oxide compound obtained from a reaction of concentrated nitric acid and P₄O₁₀ (in 4 : 1 ratio) is acidic in nature.
