CuO2H2

CuO2H2, also known as copper(II) hydroxide, is a chemical compound with the formula Cu(OH)2. It is a blue-green solid that is insoluble in water. Copper(II) hydroxide is formed when copper(II) ions react with hydroxide ions in an aqueous solution. It is a basic compound, meaning it can react with acids to form salts. Copper(II) hydroxide is used in various applications, including as a pigment in ceramics and as a precursor in the synthesis of other copper compounds. It is also used in the production of copper-based catalysts and in the treatment of water to remove heavy metals. The compound is toxic if ingested or inhaled, and proper safety measures should be taken when handling it. Copper(II) hydroxide is a stable compound under normal conditions, but it can decompose when heated, releasing water and forming copper(II) oxide.
