Anhydrous ammonia

Ammonia is a colorless gas that is easily recognized because of its pungent odor. Ammonia is often encountered as anhydrous ammonia. Describe anhydrous ammonia and at least three of its commercial uses. When there is a release, explain why emergency responders should not apply water directly to the release of aqueous ammonia. Provide its chemical reaction with water.

Full Answer Section
    • Refrigerant: Anhydrous ammonia is a very effective refrigerant, and it is used in a variety of refrigeration systems.
    • Chemical intermediate: Anhydrous ammonia is used to produce a variety of other chemicals, including plastics, explosives, and pharmaceuticals.
When there is a release of anhydrous ammonia, emergency responders should not apply water directly to the release. This is because the water will react with the ammonia to form a mist of ammonium hydroxide, which is a highly corrosive and irritating substance. The mist can cause severe burns to the eyes, skin, and respiratory tract. The chemical reaction between anhydrous ammonia and water is as follows:
NH3 + H2O → NH4OH
This reaction produces ammonium hydroxide, which is a strong base. Ammonium hydroxide can cause severe burns to the eyes, skin, and respiratory tract. It can also be harmful if inhaled or ingested. If there is a release of anhydrous ammonia, emergency responders should evacuate the area and call for assistance. They should not attempt to approach the release or apply water to it.
Sample Answer here is some information about anhydrous ammonia:
  • Anhydrous ammonia is a colorless, odorless gas at standard temperature and pressure. It is a liquefied gas under pressure and is commonly stored and transported in this form.
  • Anhydrous ammonia is a highly soluble gas in water, and when it comes into contact with water, it forms a solution called aqueous ammonia. Aqueous ammonia is a strong base and can be corrosive to metals and other materials.
  • Anhydrous ammonia is a widely used industrial chemical, and it has a number of commercial applications, including:
    • Fertilizer: Anhydrous ammonia is a major component of nitrogen fertilizer. It is used to increase crop yields and improve soil quality.
