Applications
Applications of ammonia include the following:
- One of its primary uses is as a fertilizer
- In extracting metals such as copper, nickel, and molybdenum from their ores
- As a processing agent, ammonia is used in the manufacturing of alkalis, ammonium salts, dyes, pharmaceuticals, cuprammonium rayon, and nylon
- When diluted in water, it is used as a common household cleaning agent
- More concentrated forms are used as chemical reagents
- Used in the rubber industry for stabilization of raw latex to prevent coagulation during transportation and storage
- A source of nitrogen for microorganisms and to adjust pH during fermentation
- It is a useful refrigerant due to its vaporization properties
