The aluminum bromide It is a compound made up of an aluminum atom and a varied number of bromine atoms. It is formed depending on the number of valence electrons that aluminum has.
Being a compound joined by a metal (aluminum) and a nonmetal (bromine), covalent bonds are formed that give the structures a very good stability, but without reaching that of an ionic bond..
Aluminum bromide is a substance that normally occurs in a solid state, with a crystalline structure.
The colors of the different aluminum bromides appear as pale yellows of different shades, and sometimes appear without apparent color.
The color depends on the light reflection capacity of the compound and changes depending on the structures that are created and the forms that it takes..
The solid state of these compounds crystallizes, so they have well-defined structures with an appearance similar to sea salt, but varying in color..
Aluminum bromide is made up of an aluminum atom (Al) and different amounts of bromine atoms (Br), depending on the valence electrons that aluminum has..
For this reason, the general formula for aluminum bromide can be written as follows: AlBrx, where "x" is the number of bromine atoms that bind to aluminum.
The most common form in which it occurs is as Al2Br6, which is a molecule with two aluminum atoms as the main bases of the structure..
The bonds between them are formed by two bromines in the middle, so that each aluminum atom has four Bromine atoms in its structure, but in turn, they share two.
Due to its nature, it is highly soluble in water but it is also partially soluble in compounds such as methanol and acetone, unlike other types of substances..
It has a molecular weight of 267 g / mol and is formed by covalent bonds.
Sodium bromide reaches its boiling point at 255 ° C, and reaches its melting point at 97.5 ° C.
Another characteristic of this compound is that it emits toxins when it evaporates, so it is not recommended to work with it at high temperatures without adequate protection and relevant safety knowledge..
One of the uses given to this type of substance due to its metallic and non-metallic nature is that of agents in chemical purity tests..
Purity testing is very important in determining the quality of reagents and making products that people are satisfied with..
In scientific research it is used in a very variable way. For example, to form complex structures, agents in the synthesis of other valuable chemical products, in the hydrogenation of dihydroxynaphthalenes and in the selectivity in reactions, among other uses..
This compound is not commercially popular. As seen above, it has some applications that are very specific, but very interesting for the scientific community..
