Frequently Asked Questions on Ammonia

What is the Chemical Formula of Ammonia?

The chemical symbol for ammonia is NH₃​. This represents a molecule of ammonia consisting of one nitrogen atom (N) and three hydrogen atoms (H).

What is the Structure of Ammonia?

The structure of ammonia (NH₃) is trigonal pyramidal. This molecule consists of one nitrogen atom (N) at the center with three hydrogen atoms (H) symmetrically spaced around it.

What are Properties of Ammonia?

Ammonia is a colourless gas with a distinctive pungent ammoniacal odour. It is lighter than air and may easily liquefy at room temperature when subjected to a pressure of 8 to 10 atmospheres. Under one atmosphere pressure, its boiling point is –33.5^∘C(239.6K). It serves as a Lewis foundation.

What is the Preparation Method of Ammonia?

Haber’s technology is used to produce ammonia on a commercial basis.

N₂ (g) + 3H₂ ⇌ NH₃ (g)  ; ΔH^∘=–92.4kJ/mol

This reaction is carried out in the presence of iron oxide as a catalyst with a little amount of K₂O and Al₂O₃ at a temperature of 700K and a pressure of 200×10⁵Pa or 200 atmospheres. Molybdenum is utilised as a promoter to improve the catalyst’s efficiency.

What are the Uses of Ammonia?

Ammonia is used as:

1. In the production of nitric acid by Ostwald’s process, sodium carbonate by Solvay’s process, and rayon and urea by Solvay’s process.
2. In the production of fertilizers such ammonium sulphate, ammonium nitrate, urea, and diammonium phosphate, among others.
3. In ice plants as a refrigerant.
4. As a surface cleaner for furniture and glass.
5. In the laboratory, it is utilised as a solvent and as a reagent.

What Type of Reaction is the Synthesis of Ammonia by Haber’s process?

Haber’s technique produces ammonia through a reversible, exothermic reaction that results in a drop in volume. We hope you found this ammonia post useful. If you have any questions, please leave a comment below and we will respond as soon as possible.
