Uses
Primary
- Source of elemental copper
- Ultimate source of most most copper (II) compounds, including copper (II) acetate and copper (II) chloride.
Secondary
- Part of early paths to sulfuric acid
Natural occurrence
Hazards
Production
Extraction
Grind malachite or azurite into a fine powder and pan. (separate by mass)
Synthesis
Combine copper sulfate and sodium bicarbonate in water giving copper carbonate
- 2 CuSO4 + 2 NaHCO3 + H2O → Cu2(OH)2CO3 + 2 NaHSO4 + CO2
- 2 CuSO4 + 2 NaCO3 + H2O → Cu2(OH)2CO3 + 2 NaSO4 + CO2
Testing
Purification
Storage
- Storable in open container
Disposal
- Can be released into non-watery environment
