Potassium Hydroxide Pellets (KOH), also known as caustic potash, are a high-purity, versatile chemical compound used extensively in industrial and laboratory applications. These white, odorless pellets are highly soluble in water, producing a strongly alkaline solution. Potassium Hydroxide is renowned for its effectiveness in neutralization reactions, pH regulation, and as a critical ingredient in many industrial processes.
Applications

Safety and Handling
Hazards
Potassium Hydroxide is highly caustic and can cause severe burns, irritation, or damage upon contact with skin, eyes, or mucous membranes. It reacts violently with water, acids, and certain organic materials.
Precautions
- Personal Protective Equipment (PPE): Always wear gloves, safety goggles, and protective clothing.
- Ventilation: Use in a well-ventilated area or under a fume hood to avoid inhaling fumes.
- Storage: Store in a dry, cool, and well-sealed container away from moisture, acids, and incompatible materials.
- Handling: Use dedicated tools and containers to avoid accidental contamination.
First Aid Measures
- Skin Contact: Rinse thoroughly with water for at least 15 minutes. Seek immediate medical attention if irritation persists.
- Eye Contact: Flush eyes with water for at least 15 minutes and consult a physician.
- Inhalation: Move to fresh air and seek medical help if respiratory distress occurs.
- Ingestion: Do not induce vomiting. Rinse mouth with water and seek urgent medical attention.
Environmental Considerations
KOH is hazardous to aquatic life and ecosystems. Avoid releasing into waterways. Dispose of waste and residues in compliance with local environmental regulations.
