What is Bi(OH)3? Important knowledge about Bi(OH)3.

  1. Definition of Bi(OH)3
    Bi(OH)3, also known as bismuth hydroxide, is a chemical substance with the chemical structure Bi(OH)3. In English, we call this substance Bismuth hydroxide. Bi(OH)3 consists of 1 Bismuth atom (Bi), and 3 Hydroxide atoms (OH). The atomic mass of Bi(OH)3 is 260.98 g/mol. The molecule of Bi(OH)3 consists of 1 Bi3+ ion and 3 OH- ions.

  2. Properties of Bi(OH)3
    Bi(OH)3 in solid form is colorless and odorless. Its pH when dissolved in water is very high, indicating that Bi(OH)3 is a strong alkali. In chemical reactions, it can participate in acid-base, oxidation-reduction reactions.

  3. Common chemical equations of Bi(OH)3
    Bi(OH)3 participates in many chemical reactions, such as reactions with metals, acids, nonmetals, and salts. For example, the reaction between Bi(OH)3 and HCl acid produces the salt BiCl3 and water.
    Bi(OH)3 + 3HCl -> BiCl3 + 3H2O

  4. Synthesis of Bi(OH)3
    Bi(OH)3 can be synthesized in the laboratory through the reaction between bismuth salt and alkali metal hydroxide. For example, when the bismuth nitrate salt [Bi(NO3)3] reacts with a sodium hydroxide (NaOH) solution, we get the precipitate of Bi(OH)3.
    Bi(NO3)3 + 3NaOH -> Bi(OH)3↓ + 3NaNO3

On an industrial scale, Bi(OH)3 is typically produced by separating Bi from Bi-containing sources such as ore, through oxidation and precipitation processes.
