Aqeous Ammonia Solution Extra Pure is a high-purity, clear, colorless liquid consisting of ammonia gas dissolved in water, emitting a strong, characteristic odor. It is widely used in laboratory chemistry as a weak base and complexing agent in acid-base titrations, buffer preparation, and qualitative inorganic analysis, particularly for detecting metal ions through complex formation. It also plays a role in pH adjustment, sample preparation, and synthesis of ammonium compounds. The extra pure grade ensures low levels of impurities, making it ideal for sensitive analytical procedures and high-precision research. Due to its volatility and corrosive nature, it should be handled in well-ventilated areas and stored in tightly sealed, chemical-resistant containers away from heat and direct sunlight.

Aqeous Ammonia Solution Extra Pure

Primary Uses

Alkaline Reagent and pH Adjuster
- Commonly used to raise pH in titrations, buffer preparation, and general aqueous reactions.
Complexing Agent in Inorganic Analysis
- Forms ammonia complexes with metal ions (e.g., Cu²⁺, Ag⁺, Ni²⁺), aiding in qualitative analysis and separation of cations.
Precipitant in Group III and IV Inorganic Qualitative Analysis
- Used to precipitate metal hydroxides such as Fe(OH)₃, Al(OH)₃, Zn(OH)₂ under controlled pH.
Neutralizing Agent in Acid–Base Titrations
- A weak base used in titrations and buffer studies, especially for demonstrating weak base–strong acid behavior.
Preparation of Ammonium Salts and Lab Reagents
- Reacts with acids or acidic oxides to form ammonium salts (e.g., NH₄Cl, NH₄NO₃) for synthesis or calibration.

Secondary Uses

Cleaning Agent for Glassware and Electrodes
- Removes organic residues or metal deposits from lab equipment, especially when combined with peroxide or acids (used with caution).
Reagent in Nessler’s Test for Ammonia Detection
- Forms colored complex with Nessler’s reagent — useful in trace ammonia or nitrogen analysis.
Reducing Agent in Redox Systems (Mild Conditions)
- In select systems, can act as a reducing agent or participate in redox equilibria (e.g., silver oxide reduction).
Ligand in Coordination Complex Synthesis
- Introduces labile NH₃ ligands into metal centers in coordination and transition metal chemistry studies.
Demonstration of Gas Solubility and Equilibrium
- Used to show Henry’s Law, dynamic equilibria, and acid–base gas absorption phenomena.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):
- Wear:
  - Lab coat
  - Chemical splash goggles
  - Nitrile or neoprene gloves
  - Face shield (for large volumes or risk of splashing)
- Use only in a fume hood—vapors are sharp and irritating.
Handling:
- Avoid inhalation of vapors.
- Prevent contact with skin, eyes, or clothing.
- Open containers carefully—ammonia fumes are volatile and corrosive.
- Never mix with acids—can cause violent reactions and release large amounts of ammonia gas.
Storage:
- Keep in a tightly sealed container in a cool, well-ventilated place.
- Store away from:
  - Acids
  - Oxidizing agents
  - Heat and direct sunlight
- Use corrosion-resistant storage containers (e.g., HDPE).
Hygiene Measures:
- Wash hands after handling.
- Avoid touching your face or eyes while working with the solution.
- Clean surfaces thoroughly after spills or use.

FIRST AID MEASURES

Inhalation:
- Move the person to fresh air immediately.
- Loosen tight clothing and ensure open airways.
- Provide oxygen if breathing is labored.
- Seek urgent medical attention—vapors may cause respiratory irritation or lung damage.
Skin Contact:
- Remove contaminated clothing.
- Rinse skin with plenty of water for at least 15 minutes.
- Seek medical attention if irritation or burns develop.
Eye Contact:
- Rinse cautiously with water for at least 15 minutes, holding eyelids apart.
- Remove contact lenses if present and easy to do.
- Seek immediate medical attention—can cause severe eye burns and permanent damage.
Ingestion:
- Rinse mouth thoroughly with water.
- Do not induce vomiting.
- Give water or milk if the person is fully conscious.
- Seek emergency medical care—ingestion can result in burns to the mouth, throat, and stomach.

FIRE FIGHTING MEASURES

Extinguishing Media:
- Use dry chemicals, CO₂, alcohol-resistant foam, or water spray.
- Do not use water jets directly on ammonia tanks.

Firefighting Instructions:
- Cool fire-exposed containers with water spray.
- Approach from upwind to avoid vapors.
