What is Zinc Sulphate heptahydrate and what is it used for?

Zinc sulphate heptahydrate also known as Zinc Sulfate is white crystal powder with the formula ZnSO4.7H2O. It was historically known as "white vitriol". All of the various forms are colorless solids. It used as trace element fertilizer to prevent crops from Zn deficiency and increase crop yields. Now more and more farmers apply micronutrient fertilizers such as zinc sulfate.

How does zinc sulfate dissolved well in water?

ccording to the national standard, the maximum of insoluble matter in zinc sulfate water is 0.05%, however some customers find that zinc sulfate powder cannot be completely soluble in water when testing by oneself, thus begin to doubt the zinc sulfate water-solubility. How does zinc sulfate dissolved well in water?

To make zinc sulfate more completely soluble in water, the tester should control the PH of zinc sulfate solution under 6. Conversely, if solution’s PH value keeps 7.5 or above, zinc sulfate could not well soluble in water. Therefore, to accurately test zinc sulfate water-solubility, one should appropriately add acid content in solution. In acidic solution, high-quality zinc sulfate ‘s water-solubility appears very obviously.

SAFETY

Zinc sulfate powder is an eye irritant. Ingestion of trace amounts is considered safe, and zinc sulfate is added to animal feed as a source of essential zinc, at rates of up to several hundred milligrams per kilogram of feed. Excess ingestion results in acute stomach distress, with nausea and vomiting appearing at 2-8 mg/Kg of body weig
