SHORT DESCRIPTION

Barium Acetate Extra Pure is a high-purity, white crystalline compound used in laboratory chemistry for analytical, inorganic, and materials science applications. It serves as a soluble source of barium ions in solution, making it valuable for studies involving double displacement reactions, sulfate detection, and synthesis of other barium salts. Its use in gravimetric analysis and as a precursor in the preparation of specialty ceramics and optical materials is also notable. The extra pure grade ensures low impurity levels, supporting accurate and consistent results in high-precision research. It should be stored in tightly sealed containers in a cool, dry place, away from acids and moisture to maintain its chemical integrity.

Source of Barium Ions in Inorganic Reactions
- Supplies Ba²⁺ in ionic equilibrium studies, precipitation tests, and ion-exchange experiments.
Flame Test Reagent for Teaching Labs
- Used to demonstrate green barium flame coloration, aiding in elemental identification.
Model Compound in Solubility Product (Ksp) Experiments
- Helps students understand solubility equilibria and predict outcomes of double displacement reactions.

Secondary Uses

Component in Conductivity and Ion Transport Studies
- Useful in exploring the mobility of divalent ions and their interactions with anions in solution.
Synthesis of Barium-Based Coordination Complexes
- Serves as a starting material for ligand binding and structural studies involving barium and carboxylate groups.
pH Adjustment and Buffering in Non-Critical Applications
- The acetate component offers mild buffering capacity in some inorganic solutions.
Research on Acetate Salt Stability and Hydration
- Investigated for its thermal decomposition, hydration behavior, and crystal structure in solid-state chemistry.
Simulation of Environmental Precipitation Reactions
- Used to model ion removal in water treatment and pollutant precipitation processes in environmental labs.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):
- Wear chemical-resistant gloves (nitrile or neoprene), lab coat, and chemical splash goggles.
- Use in a fume hood or well-ventilated space to avoid inhaling dust.
Handling:
- Avoid inhalation of dust, ingestion, and contact with skin and eyes.
- Handle with care—toxic if swallowed or absorbed.
- Do not mix with acids—may release acetic acid fumes.
Storage:
- Store in a cool, dry, well-ventilated place.
- Keep in tightly closed containers, away from acids, moisture, and oxidizing agents.
- Clearly label as toxic.
Hygiene Measures:
- Wash hands thoroughly after handling.
- Do not eat, drink, or smoke in the lab.
- Clean spills immediately with non-metallic absorbents.

FIRST AID MEASURES

Inhalation:
- Move the person to fresh air immediately.
- Seek immediate medical attention if respiratory symptoms occur (cough, shortness of breath, chest discomfort).
Skin Contact:
- Rinse skin with plenty of water and soap.
- Remove contaminated clothing.
- Seek medical attention if irritation develops.
Eye Contact:
- Flush eyes immediately with water for at least 15 minutes, lifting eyelids occasionally.
- Remove contact lenses if present.
- Seek medical attention immediately.
Ingestion:
- Do NOT induce vomiting.
- Rinse mouth thoroughly with water.
- Give water or milk if the person is conscious.
- Seek emergency medical attention—barium compounds are highly toxic, potentially causing:
  - Muscle weakness
  - Vomiting
  - Cardiac arrhythmias
  - Hypokalemia

FIRE FIGHTING MEASURES

Suitable Extinguishing Media:
