What is a
Potassium Reaction? Definition of a Reaction
Define a Potassium
Reaction: A Potassium Reaction involves a process in which
Potassium is mixed with another substance which react to
form something else. Reactions are manifested by the
disappearance of properties characteristic of Potassium
and the appearance of new properties in the new
substance or Compound. The substances initially involved in a
reaction are called reactants or reagents. The most
important of the Potassium compounds is Potassium
chloride (KCl) which is used in the production of
fertilizers and chemicals and also as a salt substitute.
Other important compounds are Potassium nitrate (KNO3),
also known as saltpeter which is used in the production
of gunpowder, fertilizers and pyrotechnics and Potassium
hydroxide (KOH) is used to make detergents and soaps. Reactions are described
Formula and Equations.
Reaction with Dilute Acids
Potassium reacts with dilute acids explosively and experiments
with these substances should never be attempted.
Potassium Hydroxide Reaction
Potassium hydroxide (KOH), commonly called caustic potash,
is an important compound of Potassium which is used to make
detergents and soaps. Potassium hydroxide dissolves readily in
water, and gives off considerable heat and forms a strongly
alkaline, caustic solution.
and Water Reaction
When small pieces of Potassium
are added to water this results in a hissing sound and the
substance burns with a lilac flame. Hydrogen gas is given out in
the reaction and potassium hydroxide is formed.
Potassium + Water —>
Potassium hydroxide + Hydrogen
Potassium Nitrate Reaction
Potassium nitrate (KNO3), also known as saltpeter,
is an important compound of Potassium which is used in the
production of fertilizers, matches, gunpowder and pyrotechnics.
Potassium nitrate is slightly soluble in cold water and very
soluble in hot water. It is prepared by the reaction of
potassium chloride with sodium nitrate. When it is heated
potassium nitrate decomposes and releases oxygen.
Potassium Chloride Reaction
Potassium chloride (KCl) is an important Potassium compound
which is used in the production of fertilizers and chemicals and
also as a salt substitute. Potassium chloride is soluble in
water, alcohol, and alkalies and insoluble in alcohol. Potassium
reacts with dilute hydrochloric acid to give potassium chloride
and hydrogen gas.
Potassium + Dilute
hydrochloric acid —> Potassium chloride + Hydrogen
small pieces of Potassium
in air results in the substance melting without any flame being
seen and turning instantly into a mixture of potassium peroxide
and potassium super oxide. Larger pieces of potassium burn with
a lilac flame.
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:
