Natural occurrence
Calcium nitrate occurs naturally as a result of bacterial nitrification in compost
Hazards
Production
Synthesis
- Neutralize nitric acid with a calcium salt (calcium carbonate)
- 2 HNO3 + CaCO3 → Ca(NO3)2 + CO2 + H2O
- Metathesis: silver nitrate and calcium chloride yield silver chloride and a calcium nitrate solution
- 2 AgNO3(aq) + CaCl2(aq) → 2 AgCl(s) + Ca(NO3)2(aq)
Extraction
- Leach compost with water (see also ammonia biofiltration)
