Barium Chloride Extra Pure

Primary Uses

Reagent for Sulfate Ion Detection
- Widely used in qualitative analysis to test for SO₄²⁻, forming insoluble barium sulfate (BaSO₄) — a key gravimetric determination method.
Source of Barium Ions in Inorganic Reactions
- Supplies Ba²⁺ ions for precipitation reactions, ionic strength control, and crystal lattice formation in coordination studies.
Flame Test Reagent
- Produces a green flame, making it useful in elemental identification and flame spectroscopy demonstrations.
Standard Salt for Conductivity and Ion Mobility Studies
- Commonly used in solution conductivity experiments and studies involving cation migration.
Precursor for Barium-Based Salt Synthesis
- Reacts with sodium carbonate, phosphate, or chromate to form other barium salts for lab-scale synthesis and crystal preparation.

Secondary Uses

Teaching Reagent for Precipitation and Solubility Experiments
- Demonstrates solubility rules, Ksp (solubility product), and common ion effect in student labs.
Study of Double Displacement and Ionic Reactions
- Useful in illustrating ionic reactions in aqueous solution involving group 2 elements.
Environmental Testing of Sulfates in Water
- Applied in water analysis to detect sulfate contamination using simple dropwise precipitation tests.
Synthesis of Barium-Based Coordination Complexes
- Acts as a starting material in forming barium-ligand complexes for structure and reactivity studies.
Demonstration of Crystallization and Recrystallization
- Soluble in water and ethanol, making it a good candidate for crystal growth and purification studies.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):
- Lab coat, chemical-resistant gloves (nitrile recommended), and safety goggles.
- Use a dust mask or operate in a fume hood to prevent inhalation of fine particles.
Handling:
- Avoid inhalation, ingestion, and skin or eye contact.
- Prevent dust formation and avoid contamination with acids or moisture.
- Do not eat, drink, or smoke while handling.
Storage:
- Store in a tightly sealed container in a dry, cool, and well-ventilated area.
- Protect from moisture, acids, and incompatible substances.
- Clearly label container as Toxic and store in a designated chemical cabinet.
Environmental Precautions:
- Prevent release into drains, soil, or waterways—extremely toxic to aquatic life.
- Collect and dispose of spills with care using approved hazardous waste procedures.

FIRST AID MEASURES

Inhalation:
- Move to fresh air immediately.
- Administer oxygen if breathing is difficult.
- Seek urgent medical attention—inhalation may cause systemic toxicity.
Skin Contact:
- Wash skin with plenty of water and soap.
- Remove contaminated clothing.
- Seek medical advice if irritation or symptoms occur.
Eye Contact:
- Rinse thoroughly with water for at least 15 minutes.
- Lift eyelids occasionally.
- Seek immediate medical attention—may cause severe irritation or burns.
Ingestion:
- Do not induce vomiting.
- Rinse mouth with water.
- If conscious, give water or milk to dilute.
- Seek emergency medical care—barium chloride is highly toxic and may cause:
  - Hypokalemia
  - Muscle weakness or paralysis
  - Cardiac arrhythmias
  - Seizures or death

FIRE FIGHTING MEASURES
