Copper Hydroxide, a compound characterized by the formula Cu(OH)₂, is a substance of considerable interest due to its unique chemical and physical properties. While widely utilized as a fungicide and bactericide in agriculture, a deeper understanding of its chemistry reveals its broader applicability across various industrial sectors. As a dedicated chemical supplier, we provide high-quality Copper Hydroxide and aim to educate our clients on its fundamental characteristics. Understanding these properties is crucial for effective procurement and application.

Physically, Copper Hydroxide typically appears as a blue or bluish-green gelatinous solid or a light blue crystalline powder. Its relative density is approximately 3.368. A key characteristic influencing its use is its solubility: it readily dissolves in acids, ammonia water, and solutions of alkali metal cyanides and carbonates, but it is insoluble in water. This differential solubility is important for its formulation and application methods. When heated, it undergoes changes, darkening at 60-80°C and decomposing into black cupric oxide and water at higher temperatures, indicating its thermal stability profile.

Chemically, Copper Hydroxide reacts with acids to form copper salts and water. For example, its reaction with sulfuric acid yields copper sulfate and water: Cu(OH)₂ + H₂SO₄ → CuSO₄ + 2H₂O. This reactivity makes it a precursor for the synthesis of various copper compounds. Its role as a weak base, as opposed to a strong alkali due to its low solubility in water, is also a notable chemical property.

The efficacy of Copper Hydroxide as a fungicide and bactericide stems from the release of copper ions (Cu²⁺). These ions interfere with essential cellular functions of fungi and bacteria, such as enzyme activity and cell membrane integrity. This mode of action makes it a multi-site inhibitor, theoretically reducing the risk of resistance development, although some bacterial resistance has been noted with prolonged use.

For agricultural and industrial users, understanding these properties is vital for effective product selection. The availability of different grades, such as pesticide grade with specific copper content percentages, or high-purity grades for laboratory use, caters to diverse needs. As a supplier, we ensure that our Copper Hydroxide meets precise specifications, including low levels of impurities like heavy metals, which is critical for sensitive applications. Whether for crop protection, industrial catalysis, or pigment formulation, the inherent chemical characteristics of Copper Hydroxide dictate its performance.

In conclusion, the chemical and physical properties of Copper Hydroxide are fundamental to its wide-ranging utility. Its insolubility in water, reactivity with acids, and the biocidal action of released copper ions make it a valuable compound. We are committed to providing our clients with access to this essential chemical, offering various grades and ensuring high standards of quality. We encourage prospective buyers to consult detailed product specifications when considering their procurement of Copper Hydroxide.
