What is Cu(OH)2? Important knowledge about Cu(OH)2.

  1. Definition of Cu(OH)2
    Cu(OH)2, also known as copper (II) hydroxide or copper hydrate, is a chemical compound of solvent, copper, and hydroxide. It has a molar mass of 97.561 g/mol and consists of one copper (II) ion and two hydroxide ions. In this molecule, the copper ion has two valence electrons and forms an octahedral molecular structure.

  2. Properties: Cu(OH)2
    Copper (II) hydroxide typically exists as a pale blue, odorless powder with a basic pH. It is insoluble in water but soluble in solutions containing ammonium ions. Cu(OH)2 is not easily combustible and has no biological activity.

  3. Common chemical equations involving Cu(OH)2
    Cu(OH)2 participates in various reactions. In reactions with acids, it forms copper salts and water. For example: Cu(OH)2 + 2HCl -> CuCl2 + 2H2O. It can also react with lighter metals to form pure copper and a new metal hydroxide. In reactions with nonmetals, it typically forms complex copper compounds.

  4. Preparation of Cu(OH)2
    Copper (II) hydroxide can be prepared in the laboratory by reacting a solution of copper (II) sulfate with an alkali. For example: CuSO4 + 2NaOH -> Cu(OH)2↓ + Na2SO4. Industrially, copper hydroxide is usually produced by reacting a solution of copper (II) sulfate or chlorhydrate with an alkali.
