1) Physical and chemical property:
Molecular formula: ZnSO4 7H2O
Molecular weight: 287.56
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
It is mainly used in the industries of organic synthesis, such as
dehydrating agent, condensating agent, wood antiseptic, fabric
starching agent, weighting agent, battery, electroplating,
papermaking, medicine, active carbon and so on.
3)Characteristic and function:
