Ammonia is a compound made of nitrogen and hydrogen with the chemical formula NH3. It is a colorless gas with a characteristic pungent odor. Ammonia is commonly used in household cleaning products, fertilizers, and various industrial applications. It is also produced in nature through biological processes, such as animal waste and decomposition of organic matter.
Properties of Ammonia
- Odor: Strong, pungent smell
- Solubility: Highly soluble in water
- Boiling Point: -33.34°C
- Flammability: Not flammable, but can support combustion
- Uses: Fertilizer production, cleaning products, refrigeration, and more
Study Guide
Here are some key points to remember about ammonia:
- Ammonia is composed of nitrogen and hydrogen atoms in a 1:3 ratio.
- It is a key component in the production of fertilizers, providing essential nitrogen for plant growth.
- Ammonia is a weak base and can react with acids to form ammonium salts.
- It is highly soluble in water, forming ammonium hydroxide, which is a common cleaning agent.
- Ammonia has a characteristic odor that can be detected even at low concentrations.
- Exposure to high levels of ammonia can be harmful to human health, causing irritation to the respiratory system and eyes.
- Ammonia is also used in refrigeration systems as a coolant.
