Arsenic Tribromide[edit]

Arsenic tribromide is a chemical compound with the formula AsBr_. It is a colorless or pale yellow solid that is highly soluble in water and other polar solvents. Arsenic tribromide is primarily used in the synthesis of other arsenic compounds and in various chemical reactions.

Structure and Properties[edit]

Arsenic tribromide is a molecular compound that consists of one arsenic atom covalently bonded to three bromine atoms. The compound adopts a trigonal pyramidal geometry, similar to that of phosphorus tribromide. The As-Br bond length is approximately 2.42 Å.

The compound is known for its volatility and can be sublimed under reduced pressure. It has a melting point of 31.1 °C and a boiling point of 221 °C. Arsenic tribromide is highly reactive and can act as a source of bromine in various chemical reactions.

Synthesis[edit]

Arsenic tribromide can be synthesized by the direct reaction of elemental arsenic with bromine:

$2 As + 3 {Br}_{2} \to 2 {AsBr}_{3}$

This reaction is typically carried out in a controlled environment to prevent the formation of unwanted byproducts.

Applications[edit]

Arsenic tribromide is used in the preparation of other arsenic compounds, such as arsenic acid and arsenic trioxide. It is also employed in organic synthesis as a brominating agent. Due to its reactivity, arsenic tribromide is handled with care in laboratory settings.

Safety and Handling[edit]

Arsenic tribromide is highly toxic and poses significant health risks if ingested, inhaled, or absorbed through the skin. It is classified as a hazardous material and should be handled with appropriate safety precautions, including the use of personal protective equipment and proper ventilation.
