What Is Zinc Sulphate Monohydrate?
Zinc Sulphate Monohydrate is an inorganic zinc salt in which each zinc sulphate molecule is chemically bound to one molecule of water. It is commonly used as a reliable and concentrated source of zinc across agriculture, pharmaceuticals, animal nutrition, and industrial applications.
Chemical Composition & Molecular Structure: Zinc Sulphate Monohydrate has the chemical formula ZnSO₄·H₂O. It consists of zinc ions (Zn²⁺) bonded with sulphate ions (SO₄²⁻), along with a single molecule of water of crystallization. This structure provides good stability while maintaining high zinc availability for absorption and reaction in formulations.
Physical Appearance: Zinc Sulphate Monohydrate typically appears as a white to off-white crystalline powder or fine granules. Depending on processing and grade, it may be supplied in powdered or crystalline form to suit different application requirements.
Solubility & Stability Characteristics: Zinc Sulphate Monohydrate is highly soluble in water, enabling easy mixing and rapid zinc availability in solutions and formulations. It is chemically stable under normal storage conditions but is mildly hygroscopic, meaning it should be stored in dry, well-sealed packaging to prevent moisture absorption and caking.
Major Applications of Zinc Sulphate Monohydrate-
Zinc Sulphate Monohydrate is valued for its high zinc availability, consistent quality, and compatibility with a wide range of formulations. Its applications span health, nutrition, and industrial manufacturing, making it one of the most versatile zinc compounds used globally.
