1) Physical and chemical property:

Molecular formula: ZnSO4 7H2O

Molecular weight: 287.56

CAS NO.:7446-20-0.

EINECS NO.:231-793-3

Appearance: White or slight-yellow crystal, loose and no agglomeration, easy soluble in water and slightly dissolvable in alcohol and glycerol, insoluble in liquid ammonia and ketone, tending to lose water molecules of hydration in dry air and become white powder appearance. Relative density: 1.957,Melting point: 100°CWhen the temperature is 280°C, it will become no water substance and lose all crystal water. When the temperature is above 500°C, it will decompose
