FAQ

What are the physical and chemical properties of Barium Hydroxide (CAS: 17194-00-2)?

Barium hydroxide (CAS: 17194-00-2) is a white, crystalline solid with a molecular weight of approximately 171.34 g/mol. It has a high solubility in water, releasing a significant amount of heat. Chemically, it is a strong base that readily dissociates in aqueous solutions, making it highly reactive with acids. Its solubility decreases significantly with increasing temperature.

How is Barium Hydroxide (CAS: 17194-00-2) typically synthesized?

Barium hydroxide (CAS: 17194-00-2) is typically synthesized by reacting barium oxide (BaO) with water. The reaction can be represented as: BaO + H2O → Ba(OH)2. This process is exothermic and requires careful handling to manage the heat released.

What industries use Barium Hydroxide (CAS: 17194-00-2)?

Barium hydroxide (CAS: 17194-00-2) is widely used in various industries. It is an important reagent in the pharmaceuticals industry for preparation of drugs, in the polymer industry for stabilization and modification of polymers, and in the chemical industry for pH control and neutralization processes. Additionally, it has applications in sensors, semiconductors, and water treatment.

What precautions should be taken when handling Barium Hydroxide (CAS: 17194-00-2)?

When handling barium hydroxide (CAS: 17194-00-2), it is crucial to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood. Spills should be cleaned up with appropriate absorbents and the area flushed with water. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
