Uses
Primary
- Key intermediate in production of other chemicals including metallic copper, sulfuric acid and rayon.
Secondary
- Pesticide/Fungicide component
Natural occurrence
- Does (rarely) occur naturally as the mineral chalcanthite
Hazards
- Eye and skin contact with finely divided powder is irritating
- Vomiting caused by 11mg/kg oral dose
- Larger oral doses (1-12g) can be fatal
Production
Synthesis
- Combine any copper (II) salt with sulfuric acid
- CuCl2 + H2SO4 → CuSO4 + 2 HCl // copper chloride to hydrochloric acid
- Cu(CH3COO)2 + H2SO4 → CuSO4 + 2 CH3COOH // copper acetate to acetic acid.
Purification
Testing
Storage
Disposal
- In common with other copper (II) salts, combine with sodium carbonate to create insoluble copper carbonate minerals (malachite and azurite)
