Chemistry - Biomolecules Question with Solution | TestHub

Question Explanation:

The question asks which ammonium compound does not release ammonia (NH₃) gas upon heating.

Concept :

This question is based on thermal decomposition of ammonium salts.

Solution:

When heated, most ammonium salts like (NH₄)₂SO₄, (NH₄)₂CO₃, and NH₄Cl release NH₃. However, NH₄NO₃ decomposes differently, producing N₂O and H₂O instead of NH₃.

Therefore, NH₄NO₃ does not liberate ammonia on heating.

Final Answer: The correct option is (4).
