Copper hydroxide is a type of inorganic compound that has a wide range of applications. It is commonly used in agriculture as a fungicide, in the production of pigments, and in the manufacturing of batteries. In this article, we will discuss the chemical formula of copper hydroxide and its various uses.

Chemical Formula

The chemical formula for copper hydroxide is Cu(OH)2. It consists of one copper ion (Cu2+) and two hydroxide ions (OH-). This compound is a blue-green solid that is insoluble in water. Copper hydroxide is often used in its powdered form, which is easy to transport and store.

Uses in Agriculture

Copper hydroxide is commonly used in agriculture as a fungicide. It is effective against a variety of fungal diseases that can affect crops such as grapes, apples, and citrus fruits. The compound works by preventing the growth of fungal spores and inhibiting their ability to spread. Farmers often use copper hydroxide as a preventative measure, applying it to crops before the onset of disease.

Uses in Pigment Production

Copper hydroxide is also used in the production of pigments. It is a key ingredient in the creation of the pigment verdigris, which has been used since ancient times to create a greenish-blue color. Verdigris is used in paints, dyes, and cosmetics.

Uses in Battery Manufacturing

Copper hydroxide is also used in the manufacturing of batteries. It is a key component in the production of copper oxide electrodes, which are used in rechargeable batteries. Copper hydroxide is also used in the production of copper hydroxide cathodes, which are used in electrochemical cells.

Environmental Impact

Copper hydroxide can have a negative impact on the environment if it is not used properly. If it is applied in large quantities, it can accumulate in the soil and water, leading to contamination. Additionally, copper hydroxide can be toxic to aquatic life if it is released into waterways. Farmers and manufacturers must take care to use copper hydroxide in a responsible manner to minimize its impact on the environment.

Safety Precautions

Copper hydroxide can be harmful if it is ingested or inhaled. It can cause irritation to the skin, eyes, and respiratory system. Therefore, it is important to wear protective clothing and equipment when handling copper hydroxide. Additionally, it should be stored in a cool, dry place away from children and pets.


Copper hydroxide is a versatile compound with a wide range of applications. Its chemical formula, Cu(OH)2, makes it useful in agriculture, pigment production, and battery manufacturing. However, it is important to use copper hydroxide responsibly to minimize its impact on the environment and to take appropriate safety precautions when handling it.
