Name: zinc sulfate heptahydrate
Molecular formula: ZnSO4.7H2O
Properties: White granular or powder, orthorhombic crystal, there are convergence, in the dry air will be pulverized. 30℃ lose heat to the part of crystal water, 100℃ when the loss of six molecules of crystal water,280 ℃ when the loss of seven molecules of crystal water, 767℃ decomposes into ZnO and SO3. Soluble in water, slightly soluble in ethanol and glycerol. Need airtight preservation.
Uses: mainly used for manufacturing other zinc salts of barium and zinc raw materials, viscose fiber and is an important auxiliary vinylon fiber raw material, also used as a mordant dyeing, wood and leather preservatives, glue clarification and preservative, medicine emetic and fungicides, in agriculture as a trace element fertilizers.
