Lime Water 500ML L/P (Laboratory/Pharmaceutical grade) is a solution of calcium hydroxide in water. It is a clear, colorless liquid with various applications in laboratories and pharmaceutical settings. Here is a detailed description of its properties, features, uses, and safety considerations:

Description and Properties:

1. Chemical Formula:
   • Ca(OH)₂ (Calcium Hydroxide)
2. Concentration:
   • Saturated solution, typically containing about 0.15% calcium hydroxide by weight.
3. Appearance:
   • Clear, colorless liquid.
4. Packaging:
   • Supplied in a 500-milliliter container, sufficient for various laboratory and pharmaceutical uses.

Features:

1. High Purity:
   • Laboratory/Pharmaceutical (L/P) grade ensures high purity suitable for precise laboratory and pharmaceutical applications.
2. Stability:
   • The solution is stable under normal conditions but should be protected from carbon dioxide to prevent the formation of calcium carbonate precipitate.
3. Ready-to-Use:
   • Provided as a ready-to-use solution, eliminating the need for preparation and ensuring consistency.

Uses:

1. Chemical Reagent:
   • Used as a reagent in laboratories for various chemical reactions, including the detection of carbon dioxide (CO₂) in gas samples. When CO₂ is bubbled through lime water, it turns milky due to the formation of calcium carbonate.
2. Neutralization:
   • Employed to neutralize acidic solutions in various chemical processes.
3. Pharmaceutical Applications:
   • Sometimes used in pharmaceutical formulations and preparations.
4. Educational Demonstrations:
   • Commonly used in educational settings for demonstrations and experiments involving acid-base reactions and gas detection.
5. Water Treatment:
   • Utilized in small-scale water treatment processes to adjust pH and remove impurities.

Safety Considerations:

1. Handling:
   • Handle with care, using appropriate personal protective equipment (PPE) such as gloves, lab coat, and safety goggles to avoid contact with skin and eyes.
   • Avoid inhalation of vapors; use in a well-ventilated area.
2. Storage:
   • Store in a cool, dry place away from direct sunlight and incompatible substances.
   • Keep the container tightly closed to prevent the absorption of carbon dioxide from the air, which can lead to precipitation of calcium carbonate.
3. Disposal:
   • Dispose of any waste material according to local regulations and guidelines for chemical substances to prevent environmental contamination.
4. First Aid Measures:
   • Skin Contact: Rinse immediately with plenty of water. Remove contaminated clothing and seek medical advice if irritation persists.
   • Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and continue rinsing. Seek medical attention if irritation occurs.
   • Inhalation: Move the person to fresh air and keep them at rest. Seek medical attention if symptoms occur.
   • Ingestion: Rinse mouth with water and seek medical attention immediately.

Summary:

Lime Water 500ML L/P is a high-purity calcium hydroxide solution suitable for various laboratory and pharmaceutical applications. Its stability and ready-to-use nature make it convenient for detecting carbon dioxide, neutralizing acids, and educational demonstrations. Proper handling, storage, and disposal are crucial to ensure safety and maintain the quality of the solution.
