Uses
Primary
- Component of DHS AMF (antiarrhytmic and dietary supplement)
- Drying agent
- Deicing agent
- Used in the production of calcium citrate and citric acid
- production of activated charcoal
- flux for sodium chloride in electrolytic production of sodium and chlorine
Natural occurrence
- Calcium chloride occurs naturally as the minerals chlorocalcite, sinjarite and antarcticite
Hazards
- Toxic in quantity
- Irritant
Production
Synthesis
- Mix calcium carbonate and hydrochloric acid
- CaCO3 + 2 HCl → CaCl2 + H2O + CO2
