General Properties and Industrial Significance:
Copper (II) Hydroxide, with the chemical formula Cu(OH)₂, is a pale greenish-blue or bluish-green solid. Some forms of Copper (II) Hydroxide are sold as "stabilized" copper(II) hydroxide, which likely consists of a mixture of copper(II) carbonate and hydroxide. Although it is a strong base, its low solubility in water makes this characteristic less noticeable. When dissolved in ammonia solution, Copper (II) Hydroxide becomes known as Schweizer's reagent, capable of dissolving cellulose.
Applications:
-
Production of Plant Protection Products (PPPs) as Fungicide:
Copper (II) Hydroxide is used as a fungicide to control fungal diseases in crops.
-
Production of Fertilizers to Control Root Growth:
It is used in fertilizers to help control root growth, improving plant health and development.
-
Production of Ceramics as a Colorant:
Copper (II) Hydroxide is used as a colorant in ceramics, providing vibrant colors to ceramic products.
-
Production of Viscose (Rayon) and Cellulose Fibers:
Copper (II) Hydroxide in ammonia solution, known as Schweizer's reagent, is used to dissolve cellulose, which is essential for the production of rayon and other cellulose fibers.
-
Production of Insecticides:
Copper (II) Hydroxide is used in the production of insecticides to protect plants from pests.
-
Aquarium Industry (Fish Treatment):
It is used in the aquarium industry to treat external parasites in fish, such as flukes and marine ich, without harming the fish.
-
Wood Preservation:
Copper (II) Hydroxide is used as a wood preservative, helping to extend the life of wooden products.
