Industrial-grade Zinc Sulphate Monohydrate 33%min
Molecular weight 287.56
Relatively density: 1.975
Melting point: 100ºC
Physical and chemical property
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. When the
temperature is 280ºC, it will become no water substance and lose all crystal water. When the
temperature is above 500ºC, it will decompose.
