Properties of Caustic Soda

Caustic soda is a highly caustic, odorless, and colorless substance. It is soluble in water, releasing heat during dissolution, and exhibits strong alkaline characteristics. It is corrosive to organic tissue and reactive with acids, metals, and various organic compounds. Key properties include:

• Molecular Formula: NaOH

• Molecular Weight: 40.00 g/mol

• Appearance: White solid (flakes, pearls) or clear colorless liquid

• Solubility: Highly soluble in water and ethanol

• pH: Approximately 13–14 in solution

Safety Tips for Handling Caustic Soda

Caustic soda is hazardous and requires strict safety precautions:

• Wear PPE: Always use gloves, goggles, and chemical-resistant clothing.

• Ventilation: Ensure adequate airflow in work areas.

• Storage: Keep in tightly sealed containers, away from acids and moisture.

• Spillage Response: Neutralize with weak acid and rinse with plenty of water.

• First Aid: In case of skin or eye contact, flush immediately with water and seek medical attention.

Training personnel and providing SDS documentation are essential for safe usage in industrial settings.
