Aluminum bromide is a product of the reaction that aluminum and bromine combined in a 1 to 3 ratio to produce a neutral compound. In its solid state, it is colorless crystals that conveniently absorb water causing old samples to be very hydrated. Together a liquid, it is a an extremely corrosive yellow that is damaging come the skin, eyes, and mouth. It has a molecular load of 266.69 g/mol

The key characteristic that aluminum bromide is its ability to absorb water, alcohol, carbon sulfide and acetone. When placed in water, warm is created from the reaction and also a cloud that fumes, which are harmful come the eyes and also lungs. The mixing of aluminum bromide v chlorine to produce aluminum chloride and bromine.

The typical name because that aluminum bromide is aluminum tribromide according to the IUPAC.

Tribromoalumane is represented by the chemistry formula AIBr3. That is dimeric, a molecule do of two comparable molecules, kind is AI2Br6.


Aluminum bromide has very small commercial use however does electroplate aluminum to steel developing a smooth, thick, adherent, and also shiny finish. The services of the process is the formation of a thick thick surface on the steel that is corrosion resistant. Making use of aluminum bromide to perform electroplating has been discovered to be much better than using aluminum chloride, due to the fact that it forms a stronger bond with the steel. It deserve to be provided on ferrous and non-ferrous metals, which broadens its range of applications. The water-less version is supplied in organic synthesis in the Friedel-Crafts acylation, a catalyst in a molecule transforming reaction. Used with chloroform, aluminum bromide serves together a bromate agent.

Chemical Formula

The chemistry formula for aluminum bromide is AIBr3.


Aluminum bromide has one aluminum ion combined with 3 bromide ions. It is do by pouring powdered aluminum into a container of fluid bromine. The reaction can be reversed by significantly increasing the temperature that the solution. Aluminum bromide reacts conveniently with alcohol and also carboxylic acids however not together violently together it does with water. During the aluminum bromide synthesis, a significant amount that heat and also energy is exit from the reaction come the enthalpy.

Safety Concerns

Aluminum bromide is a very corrosive and also toxic problem that will burn the skin and also do permanent damage to the eyes. Breath in aluminum bromide irritates the nose, throat and also lungs bring about coughing and also shortness of breath. It shows up on the hazardous substance list of the ACGIH, DOT, and NIOSH and should be established with an ideal label. Use of aluminum bromide must be restricted to a chemistry fume hood offered its volatile nature.
