Ytterbium(iii) sulfate octahydrate(CAS: 10034-98-7)

Ytterbium(iii) sulfate octahydrate is a white crystalline solid with a high molecular weight. It has a solubility in water of 0.3 g/L at 25°C. Chemically, it is slightly acidic and reacts with bases to form ytterbium hydroxide. It is stable under normal conditions but can release hydrogen ions in acidic environments.

Ytterbium(iii) sulfate octahydrate is typically synthesized by reacting ytterbium(III) oxide or chloride with sulfuric acid. The reaction is carried out in a solution, and upon evaporation, the hydrate crystallizes. Commonly, this process involves controlling the temperature and stirring rate to achieve the desired purity and yield.

Ytterbium(iii) sulfate octahydrate is used in various industries. In pharmaceuticals, it serves as a source of ytterbium for medical applications. In polymers, it can act as a catalyst for certain reactions. It is also used in the development of sensors for ytterbium detection and in semiconductor manufacturing for doping processes.

When handling Ytterbium(iii) sulfate octahydrate, wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Use a fume hood during operations to minimize inhalation risks. Store the compound in a dry, cool place away from acidic substances. In case of a spill, neutralize with a base and dispose of according to local hazardous waste regulations. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures.
