Detailed Product Description for Copper Sulfate
What is Copper Sulfate?
Copper sulfate (CuSO₄) is a highly versatile compound that is commonly used in agriculture, water treatment, industrial processes, and food industry applications. It comes in two major forms:
Copper Sulfate Pentahydrate (CuSO₄·5H₂O) – Known for its bright blue crystals, this form is the most commonly used and widely available.
Copper Sulfate Monohydrate (CuSO₄·H₂O) – This form is more concentrated and usually appears as a light blue powder.
Applications of Copper Sulfate
📌 Agricultural Industry – Fungicide, Pesticide & Fertilizer
Copper sulfate is a highly effective chemical in agriculture for:
✔ Fungicide & Bactericide – Used to control fungal and bacterial diseases in crops like grapes, tomatoes, and potatoes.
✔ Bordeaux Mixture – When mixed with lime, it forms a powerful fungicide to protect crops.
✔ Micronutrient Fertilizer – Corrects copper deficiencies in soil, enhancing plant growth.
✔ Livestock Feed Additive – Provides essential copper to animals, improving health, growth, and immune function.
📌 Water Treatment Industry – Algaecide & Disinfectant
