What is an Aluminum Reaction? Definition of a Reaction
Define an Aluminum
Reaction: An Aluminum Reaction involves a process in
which Aluminum is mixed with another substance which
react to form something else. Reactions are manifested
by the disappearance of properties characteristic of
Aluminum and the appearance of new properties in the new
substance or Compound. The substances initially involved in a
reaction are called reactants or reagents. Aluminum is a
silvery white metal, that is so reactive chemically that
it always occurs in compounds. An important compound of
this element is aluminum sulfate which is a colourless
salt obtained by the action of sulfuric acid on hydrated
aluminum oxide. Reactions are described
with Chemical
Formula and Equations.
Aluminum
Properties
The
properties of Aluminum include low density, high thermal
conductivity, high electrical conductivity, high plasticity and
high resistance to corrosion.
Aluminum
and
Water Reaction
Aluminum reacts explosively with water but does not react
with cold water. Most of the aluminum salts dissolve well in
water. A strong layer of aluminium oxide coats the metal which
sometimes prevents the reaction with steam to give aluminium
oxide and hydrogen gas. This chloride is used as a wood
preservative or catalyst.
Aluminium + Steam
—> Aluminium oxide + Hydrogen
Aluminum
Chloride Reaction
Aluminum Chloride is a compound of aluminium and chlorine
that has a very high affinity for water. Pure samples are white,
but sometimes it has a yellow colour. Aluminum and chlorine do
not react rapidly at room temperature, but if the aluminum is
heated, the reaction is vigorous. It fumes in moist air and
hisses when mixed with liquid water. The product is aluminum
chloride, a white powder that fumes in air, reacting with water
to form HCl gas and aluminum oxide.
Aluminum Oxide Reaction with Oxygen
Powdered
Aluminum powdered burns energetically in air. During
combustion of aluminum in an oxygen current, a temperature of
over 3000°C is reached. Strong heating is required to make
aluminium powder burn in oxygen and a white powder is formed.
The ability of aluminum to combine actively with oxygen is used
in the reduction of metals from their oxides.
Aluminium + Oxygen
—> Aluminium oxide
Aluminum
Reactions
Examples of Aluminum Reactions are as
follows:
-
Aluminum reacts with Hydrogen to form Aluminum hydride
-
Aluminum chloride reacts with lithium hydride to form Lithium aluminum
hydride
-
Aluminium reacts with dilute hydrochloric acid to form aluminium
chloride and hydrogen gas
-
Chlorine and
liquid bromine react with aluminum at room temperature
-
Iodine reacts with aluminum during heating
-
At
high temperatures, aluminum reacts with nitrogen, carbon, and sulfur,
forming aluminum nitride , carbide and sulfide
-
Aluminium reacts with dilute sulphuric acid to form aluminium sulphate
and hydrogen gas
-
Aluminium reacts with dilute nitric acid to form aluminium nitrate and
hydrogen gas
Chemical Reactions
Some examples of a chemical reaction include most commonly burning, fermentation,
tarnishing and rusting. There are several different types of Chemical reaction
which have been detailed below:
