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:
- In the production of nitric acid by Ostwald’s process, sodium carbonate by Solvay’s process, and rayon and urea by Solvay’s process.
- In the production of fertilizers such ammonium sulphate, ammonium nitrate, urea, and diammonium phosphate, among others.
- In ice plants as a refrigerant.
- As a surface cleaner for furniture and glass.
- 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.
