Zinc Sulphate Heptahydrate 99.0-102.0%
Zinc Sulphate Heptahydrate
Molecular formula: ZnSO4 7H2O
Zinc sulphate is an inorganic compound and dietary supplement. As a supplement it is used to treat zinc deficiency and to prevent the condition in those at high risk. Side effects of excess supplementation may include abdominal pain, vomiting, headache, and tiredness.
It was historically known as "white vitriol". All of the various forms are colourless solids. The heptahydrate form is commonly encountered.
In Medicine is used together with oral rehydration therapy (ORT) and an astringent.
The hydrates, especially the heptahydrate, are the primary forms used commercially. The main application is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone.
It is also used as an electrolyte for zinc electroplating, as a mordant in dyeing, and as a preservative for skins and leather.
Zinc sulphate is used to supply zinc in animal feeds, fertilizers, toothpaste, and agricultural sprays. Zinc sulphate, like many zinc compounds, can be used to control moss growth on roofs.
Zinc sulphate can be used to supplement zinc in the brewing process. Zinc is a necessary nutrient for optimal yeast health and performance, although it is not necessary for low-gravity beers as the grains commonly used in brewing already provide adequate zinc.
