Zinc chloride (ZnCl₂) is a white crystalline solid that is highly soluble in water. It is hygroscopic, meaning it can absorb moisture from the air. Zinc chloride is commonly used in various industrial applications, such as a flux for soldering, a catalyst in organic synthesis, and a wood preservative. It also has uses in textile processing, chemical synthesis, and as a disinfectant. Due to its ability to dissolve in water and its caustic nature, it should be handled with care, using appropriate safety measures.

Safety Precautions

When handling zinc chloride (ZnCl₂) in the laboratory, it’s crucial to follow safety precautions to prevent harm:

  1. Personal Protective Equipment (PPE):
    • Gloves: Wear chemical-resistant gloves to avoid skin contact.
    • Eye Protection: Use safety goggles or a face shield to protect your eyes from splashes.
    • Lab Coat: Wear a lab coat to protect your skin and clothing.
  2. Ventilation:
    • Work in a well-ventilated area or under a fume hood to avoid inhaling dust or fumes.
  3. Handling:
    • Avoid direct contact with the skin and eyes.
    • Handle zinc chloride with care, as it is corrosive and can cause burns.
  4. Storage:
    • Store zinc chloride in a tightly sealed container, away from moisture and incompatible materials (such as strong bases and oxidizing agents).
    • Keep the storage area cool, dry, and well-ventilated.
  5. Spill Response:
    • In case of a spill, evacuate the area and ventilate it.
    • Use appropriate protective equipment to clean up the spill. Neutralize the spill with a weak acid or base if necessary and dispose of it according to local regulations.
  6. Disposal:
    • Dispose of zinc chloride waste according to local, state, and federal regulations. Consult your institution’s safety guidelines for specific disposal procedures.
  7. First Aid:
    • Skin Contact: Rinse the affected area with plenty of water for at least 15 minutes and remove contaminated clothing. Seek medical attention if irritation persists.
    • Eye Contact: Rinse the eyes with water for at least 15 minutes, lifting eyelids occasionally. Seek immediate medical attention.
    • Inhalation: Move the person to fresh air. If they have difficulty breathing, seek medical attention immediately.
    • Ingestion: Do not induce vomiting. Rinse the mouth with water and seek medical attention immediately.
