| CuSO4.5H2O ≥ | 96 | 97.4 |
| Cu ≥ | 24.43 | 24.786 |
| H2SO4 ≤ | 0.2 | 0.12 |
| As ≤ | 0.0004 | 0.0003 |
| Pb ≤ | 0.001 | 0.0008 |
| Water insoluble ≤ | 0.2 | 0.19 |
Character: Dark blue triclinic crystal or blue crystalline powder or granule. It smells like nasty metal. It slowly weathers in dry air. It’s very soluble in water and the solution is acidic. PH value of 0.1mol/L water solution is 4.17(15℃). It’s very soluble in glycerol. It’s soluble in dilute ethanol but insoluble in pure ethanol.
Usage: It is used as nutritional supplement, antimicrobial agent, firming agent and processing aid.
