General Description

Cobalt(III) hydroxide is a chemical compound known with the formula Co(OH)3. This inorganic compound, also referred to as cobalt trihydroxide, typically forms as a dark brown or black solid at room temperature. It is produced as a byproduct during the chemical reaction of cobalt salts and alkali. Its delicate structure tends to decompose in the presence of acid, releasing water and creating cobalt salts. Cobalt(III) hydroxide is not usually commercially available due to its instability, and it is often studied for its interesting chemical properties and potential applications in various industries.
