What is Aluminium Chloride (AlCl3)? 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 AlCl
3
.
Why is the formula for aluminium chloride AlCl3?
Aluminum chloride is an ionic salt with the formula AlCl3. The reason for the
three chlorine atoms is because aluminum donates an electron to each chlorine atom
. That way, all four atoms can have a complete outer shell.
Why is AlCl3 not aluminum trichloride?
However, aluminum chloride, AlCl3, is sometimes called aluminum trichloride which is not incorrect in this case because it
actually is a molecular compound
(it has very polar aluminum-chlorine covalent bonds) even though it looks like it should be ionic since it contains metal and nonmetal elements typical of ionic …
How is AlCl3 formed?
Synthesis. Aluminium chloride is manufactured on a large scale by the exothermic reaction of aluminium metal with chlorine or hydrogen chloride at temperatures between 650 to 750 °C (1,202 to 1,382 °F). Aluminum chloride may be formed
via a single displacement reaction between copper chloride and aluminum metal
.
What is AlCl3 called?
Aluminum chloride
is a chemical compound with the chemical formula AlCl3. When contaminated with iron chloride, it often displays a yellow color compared to the white pure compound. It is used in various chemical applications as a Lewis base, with anhydrous aluminium trichloride being the most commonly used Lewis acid.
What is aluminum chloride used for?
Aluminum chloride hexahydrate is an
antiperspirant
that works by affecting the cells that produce sweat. Aluminum chloride hexahydrate topical (for the skin) is used to treat excessive sweating, also called hyperhidrosis. Aluminum chloride hexahydrate may also be used for purposes not listed in this medication guide.
Is aluminum chloride safe for underarms?
According to qualified experts,
aluminum chloride is safe
. It’s been tested for over eight decades. Study after study demonstrates that there is no connection between antiperspirants and breast cancer, Alzheimer’s disease, kidney disease or any other malady.
Is AlCl3 soluble or insoluble?
AlCl3 is hygroscopic and has a noticeable affinity for water. Hence, aluminium chloride dissolves in water partially.
Is AlCl3 acidic or basic?
No, it means AlCl3 is
a weak acid
, because the only part of the molecule that is contributing to the pH of the solution is the Al+3 ion. The conjugate base of a strong acid has very little impact on the pH of the solution (with the case of Cl- and its conjugate acid, HCl).
Is AlCl3 a Lewis acid?
Aluminum chloride (AlCl
3
) is
a Lewis acid
because the aluminum atom has an open valence shell. When aluminum chloride is under discussion it is called a Lewis acid or an electrophile.
What is the pH value of AlCl3?
The pH values obtained in the 50 g and 100 g AlCl3 treatments varied
between 6.41 and 8.08
and were both lower (p<0.05) than those of the control group.
Why AlCl3 is used as a catalyst?
Anhydrous AlCl3 is used as a catalyst
because it acts as a Lewis acid which can accept electron by forming intermediates and also by speeding up the reaction
. It also leads in the creation of carbocation which is used in the electrophilic substitution reaction.
What is the Lewis structure of AlCl3?
In the AlCl3 lewis structure,
a total of 9 lone pairs are present but no lone pair on the central atom
. The molecular geometry of AlCl3 is trigonal planar with each Al-Cl bond angeled 120° to each other and its electron geometry is also trigonal planar.
What is the nature of AlCl3?
Aluminium chloride (AlCl
3
) is a compound of aluminium and chlorine. The solid has a
low melting and boiling point
, and is covalently bonded. It sublimes at 178 ° C. Molten AlCl
3
conducts electricity poorly, unlike more ionic halides such as sodium chloride.
