Zinc sulfate

Zinc sulfate is an inorganic salt composed of zinc ions and sulfate ions. It commonly occurs as colorless, water-soluble crystals, including several hydrated forms.

Sulfate: Sulfate is the polyatomic anion SO₄²⁻, formed from sulfur and oxygen. Sulfate ions pair with zinc ions to form the salt.
Dissolution: Dissolution is the dispersal of a solute into a solvent to form a solution. Water separates zinc and sulfate ions from the crystal lattice.
Zinc fertilizer: Zinc fertilizer supplies plant-available zinc to soils or crops. Zinc sulfate is a widely used source for correcting zinc deficiency in crops.
Zinc chloride: Zinc chloride is an ionic zinc compound with formula ZnCl₂. It supplies zinc but uses chloride rather than sulfate as the counterion.
Zinc: Zinc is a metallic chemical element with atomic number 30. Zinc sulfate contains zinc in its common +2 oxidation state.
Crystallization: Crystallization is the formation of an ordered solid from a solution, melt, or vapor. Evaporating zinc sulfate solutions yields crystalline products.
Dietary supplement: A dietary supplement is a product intended to add nutrients or other substances to the diet. Zinc sulfate is used in some supplements to provide dietary zinc.
Zinc nitrate: Zinc nitrate is an inorganic salt composed of zinc ions and nitrate ions. Its nitrate anion gives it different chemical behavior from zinc sulfate.
Ionic compound: An ionic compound consists of oppositely charged ions held together by electrostatic attraction. Zinc sulfate’s crystal lattice is built from charged ions.
Heptahydrate: Zinc sulfate heptahydrate, ZnSO₄·7H₂O, is a hydrated crystalline form known as goslarite. This common form contains seven water molecules per formula unit.
