Boiling Egg in Cold Water
Combination of Quicklime and Natural Sulfur
Common Name: Sulfur
Chemical name: Sulfur (S)
Solubility: NA
Melting point: 115.21 °C
Common Name: Quicklime
Chemical name: Calcium oxide (CaO)
Solubility: insoluble in methanol; reacts to form calcium hydroxide in water
Melting point: 2,613 °C
Reaction: Calcium oxide (lime) reacts with sulfur dioxide to form calcium sulfite (lime sulfur)
CaO + SO2 → CaSO3
Hazard statements from MSDS:
- Harmful if swallowed
- Causes skin irritation
- Causes serious eye irritation
Safety precautions:
- Wear goggles, gloves, and lab coat
- Work in fume hood
- Don't ingest
Warning: Lime sulfur is corrosive to living things and can cause blindness if splashed in the eyes.
Reaction: Potential contact of Quicklime, or Lime Sulfur with Water
Common Name: Lime Sulfur
Chemical name: Calcium oxide (CaO)
Solubility: insoluble in methanol; reacts to form calcium hydroxide in water
Melting point: 2,613 °C
Hazard statements from MSDS:
highly alkaline content: Lime sulfur used as a pesticide
Safety precautions:
- Wear goggles, gloves, and lab coat
