What is a
Magnesium Reaction? Definition of a Reaction
Define a Magnesium Reaction: A Magnesium Reaction involves
a process in which magnesium is mixed with another
substance which react to form something else. Reactions
are manifested by the disappearance of properties
characteristic of magnesium and the appearance
of new properties in the new substance or
Compound. The substances initially involved in a
reaction are called
reactants or reagents. Magnesium sulfate is a chemical
compound containing magnesium, sulfur and oxygen,
commonly called Epsom salt. Reactions are described
with Chemical
Formula and Equations.
Burn
Magnesium with extreme Caution!
Magnesium is a highly flammable metal and can be easy to
burn in some circumstances. Magnesium is easy to burn when it is
a powder or has been shaved into thin strips, but is difficult
to burn as a solid. Warning! Magnesium metal, and its alloys,
are explosive hazards and must be handled with extreme caution.
Magnesium
and Oxygen Reaction - Magnesium Oxide
When magnesium metal burns it reacts with oxygen found in the air to
form Magnesium Oxide, which is a compound. Intense heating is
required to make magnesium burn in oxygen. Magnesium and Oxygen
combine in a chemical reaction to form the Magnesium Oxide
compound.
Magnesium + Oxygen
—> Magnesium oxide
After it burns,
it forms a white powder of the magnesium oxide. On burning in
air, powdered magnesium produces a brilliant white light, which
includes strong ultraviolet light that can permanently damage
eyes. It is therefore extremely important to safety glasses with
welding eye protection when burning magnesium in air (oxygen
gas). Magnesium burns in steam to produce white magnesium oxide
and hydrogen gas. After it burns, a white powder of the
magnesium oxide is formed. Examples of
Combination types of reaction when magnesium is burned are as follows:
-
Magnesium and nitrogen form magnesium nitride
-
Magnesium and carbon dioxide form magnesium oxide and carbon
-
Magnesium and water form magnesium oxide and hydrogen
-
Magnesium with dilute nitric acid form magnesium nitrate and hydrogen
gas
Hydrochloric Acid and
Magnesium Reaction
Magnesium displaces hydrogen because it is more reactive.
Magnesium oxide reacts with acids. It reacts with warm dilute
hydrochloric acid to give magnesium chloride solution. Magnesium
therefore reacts with dilute hydrochloric acid to give magnesium
chloride and hydrogen gas.
Magnesium +
Hydrochloric acid —> Magnesium chloride + Hydrogen
Magnesium
Water Reaction
Magnesium does not react violently with water at room
temperature. A layer of insoluble magnesium oxide
forms around the magnesium which separates the remainder of the
magnesium from the water. Magnesium reacts slowly with hot water
to give hydrogen gas & white magnesium hydroxide, which is only
slightly soluble in water. It has virtually no reaction
with cold water. Magnesium can react vigorously with steam
giving an intense white light. Hydrogen gas is given out in the
reaction forming magnesium hydroxide.
Magnesium + Steam
—> Magnesium Oxide + Hydrogen
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:
-
Substitution reactions
-
Double
displacement reactions
-
Acid-base

-
Combustion reactions
-
Combination reactions
-
Decomposition reactions
