Question

What happens when solid aluminium and chlorine gas combine?

Answer 1

Hint : Aluminium chloride is also sometimes referred to as aluminium trichloride or aluminium$(III)$ chloride. The compound is formed when aluminium and chlorine are reacted together. Its chemical formula is written as $AlC{l_3}$.

Complete Step By Step Answer:
Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction
$2Al + 3C{l_2} = 2AlC{l_3}$
At the point when aluminum metal interacts with chlorine gas in presence of heat, violent reaction begin and Aluminum chloride powder forms. This is an exothermic reaction. Need to give heat just on time for example at the beginning of reaction. Subsequent to beginning the reaction and because of exothermic reaction raised temperature helps in auto reaction in between aluminum and Chlorine.
When the green color of the chlorine gas fills the reduction tube, start heating the aluminium foil with a Bunsen burner at the end nearest to the chlorine supply. Once the aluminium is hot, a bright glow will suddenly appear where it starts to react with chlorine.
Industrially, aluminum chloride is used in the production of aluminum metal, but it also has a wide number of uses in the chemical industry particularly as a Lewis acid. Solid aluminium chloride is covalently bonded with low melting as well as boiling point.
Anhydrous aluminium chloride is a powerful Lewis acid, capable of forming Lewis acid-base adducts with even weak Lewis bases such as benzophenone and mesitylene. It forms tetrachloroaluminate $(AlC{l_4}^ - )$ in the presence of chloride ions.

Note :
Aluminum chloride hexahydrate is an antiperspirant that works by affecting the cells that produce sweat. Aluminum chloride hexahydrate topical is used to treat excessive sweating, also called hyperhidrosis. Aluminum chloride hexahydrate may also be used for purposes not listed in this medication guide.
