Description
AMMONIA SOLUTION 25% Aq.
CAS Number: 1336-21-6
Chemical Properties:
- Chemical Formula: NH₃ (in aqueous solution)
- Concentration: 25% w/w ammonia in water
- Molar Mass: 17.03 g/mol (for ammonia)
- Appearance: Colorless liquid
- Odor: Strong, pungent ammonia smell
- Density: ~0.91 g/cm³ at 20°C
- pH: >11 (highly alkaline)
- Boiling Point: ~37°C (solution dependent, as ammonia gas is released)
- Solubility: Fully miscible with water
Applications:
- Chemical Synthesis: Used as a reagent in the production of fertilizers, explosives, and polymers.
- Cleaning Agent: Utilized in industrial cleaning processes for removing grease, oil, and stains.
- pH Adjustment: Employed in water treatment to adjust alkalinity levels.
- Laboratory Use: Acts as a source of ammonia gas for chemical reactions.
- Metal Treatment: Used in processes such as nitriding and surface treatments.
Physical and Chemical Characteristics:
- Volatility: Releases ammonia gas when exposed to air.
- Reactivity: Reacts with acids to form ammonium salts; can react violently with strong oxidizers.
- Corrosiveness: Corrosive to certain metals, including copper, brass, and zinc.
- Thermal Stability: Decomposes at elevated temperatures, releasing ammonia gas.
Notes:
Ammonia solution 25% is highly concentrated and must be handled with care. It emits a pungent, irritating gas and can cause severe irritation to the skin, eyes, and respiratory system. Proper storage in tightly closed containers is essential to prevent the release of ammonia gas. Avoid contact with acids, oxidizers, and incompatible materials.
