Soda Lime (100g)

Properties:

Soda lime is a white, granular solid composed primarily of sodium hydroxide (NaOH) and calcium oxide (CaO). It is hygroscopic and highly alkaline. Soda lime is commonly used in various chemical and industrial processes, especially in laboratories for carbon dioxide absorption.

Specification:

• Appearance: White granular solid
• Composition: Sodium Hydroxide (approximately 70%) and Calcium Oxide (approximately 30%)
• CAS Number: 1310-73-2 (NaOH), 1305-78-8 (CaO)
• pH: >12
• Melting Point: Sodium Hydroxide - 318 °C (604 °F), Calcium Oxide - 2572 °C (4662 °F)
• Solubility: Soluble in water; releases heat upon dissolution

Uses and Application:

• Used in laboratories to absorb carbon dioxide from respiratory gases.
• Commonly employed in the preparation of sodium compounds and as a drying agent.
• Applied in the treatment of wastewater and in the manufacture of glass.
• Utilized in anesthesia equipment to remove carbon dioxide from exhaled gases.

Storage:

• Store in a cool, dry place away from moisture and incompatible substances.
• Keep containers tightly closed to prevent absorption of moisture from the air.
• Label containers clearly with the product name and hazard warnings.

Hazardous Information:

• Highly corrosive; can cause severe burns to skin, eyes, and respiratory tract.
• Hygroscopic nature may lead to the formation of caustic solutions upon exposure to moisture.

Safety Measures:

• Wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat when handling.
• Use in a well-ventilated area to avoid inhalation of dust and vapors.
• If contact occurs with skin or eyes, rinse thoroughly with plenty of water for at least 15 minutes and seek medical attention.
• In case of ingestion, do not induce vomiting; seek immediate medical attention.
