Cupric Sulphate Anhydrous

Whatsapp Order

Cupric Sulphate Anhydrous (Copper(II) sulfate, anhydrous form) is a blue to green crystalline powder that is highly soluble in water. It is an inorganic compound consisting of copper, sulfur, and oxygen with the formula CuSO₄. Unlike its hydrated counterpart (CuSO₄·5H₂O), the anhydrous form contains no water molecules. It is widely used in agriculture, industry, and chemical manufacturing due to its fungicidal, algicidal, and chemical reactivity properties. The compound serves as a precursor to many copper salts and catalysts.

Description

Cupric Sulphate Anhydrous Uses

Primary Uses 

Agriculture

  • Used as a fungicide and algaecide for crops to control fungal diseases such as mildew, blight, and root rot.

  • Acts as a micronutrient fertilizer supplement providing copper, essential for plant metabolism and growth.

  • Used in animal feed as a trace mineral additive for copper deficiency prevention.

Chemical Industry

  • Utilized as a raw material for the manufacture of other copper compounds such as copper salts and catalysts.

  • Used in chemical laboratories for reagent preparation and analytical tests, including Fehling’s and Benedict’s solutions for sugar detection.

  • Employed as a mordant in dyeing and printing textiles.

 

Secondary Uses 

Water Treatment

  • Applied as an algicide to control algae growth in water bodies, reservoirs, and industrial cooling systems.

Electroplating

  • Used as an electrolyte component in copper plating baths to deposit copper metal coatings.

Veterinary Medicine

  • Included in certain topical antiseptic and antimicrobial formulations for livestock.

Pigment Production

Acts as a pigment in ceramics, paints, and inks due to its distinctive blue color.
