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

Copper sulfate is an essential water treatment chemical, helping to:
Control Algae Growth – Used in ponds, lakes, and reservoirs to prevent harmful algal blooms.
Swimming Pool Treatment – Prevents algae and bacteria growth in pools.
Industrial Wastewater Treatment – Removes heavy metals and other contaminants in wastewater.


📌 Food Industry – Nutrient Supplement & Processing Aid

In the food industry, copper sulfate is used for:
Nutritional Supplement – Provides copper, an essential trace element, in fortified foods and dietary supplements.
