FAQ

What are the physical and chemical properties of cobaltous trihydroxide (CAS: 1307-86-4)?

Cobaltous trihydroxide, also known as cobalt(II) hydroxide, has a crystalline form and a molecular weight of approximately 146.87 g/mol. It is slightly soluble in water but insoluble in ethanol. Cobaltous trihydroxide is not highly reactive under normal conditions but can hydrolyze in alkaline solutions. It is used in various applications due to its unique physicochemical properties.

How is cobaltous trihydroxide (CAS: 1307-86-4) typically synthesized?

Cobaltous trihydroxide is typically synthesized by reacting a cobalt(II) salt with an excess of sodium hydroxide. This process leads to the formation of a precipitate of cobaltous hydroxide. The reaction is usually conducted in an aqueous medium, and the product can be isolated by filtration and drying. Proper catalysts and conditions are essential for achieving high yield and selectivity.

What industries use cobaltous trihydroxide (CAS: 1307-86-4)?

Cobaltous trihydroxide is used in various industries, including pharmaceuticals for its role in chelation therapy, polymers for its catalytic properties, sensors for its redox activity, and semiconductors for its electronic properties. It is also used in pigments and coatings due to its color and stability.

What precautions should be taken when handling cobaltous trihydroxide (CAS: 1307-86-4)?

When handling cobaltous trihydroxide, it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. This compound should be handled in a well-ventilated area or a fume hood to prevent inhalation of dust. Spills should be cleaned up using appropriate methods, and proper safety data sheets (SDS) should be consulted for detailed handling and disposal instructions. Storage should be in a dry, cool place, away from heat sources and incompatible materials.
