Hydrochloric Acid (HCl), a concoction compound anaerobic acid, which is an answer of hydrogen chloride in water. Once in a while alluded to as hydrochloric corrosive or hydrogen chloride in other polar solvents, eg CH3)2CO.

Dilute hydrochloric acid is in the human stomach and warm blooded creatures - encourages the assimilation of proteins. The name "hydrochloric corrosive" originates from the old strategy for its planning with stężongo sulfuric corrosive and shake salt (corrosive salt). It is synthetically off base, yet has received and is all the time utilized.

Concentrated hydrochloric acid is a lackluster, heavier than water, steaming, and exceptionally destructive fluid.

Hydrogen chloride is disintegrated in water in a sum up to 36.7% at a temperature of 20C and along these lines can not acquire a more thought hydrochloric corrosive. As the temperature builds the most extreme grouping of hydrogen chloride in water rapidly diminishes, and along these lines the concentrated hydrochloric corrosive has a solid propensity to discharge hydrogen chloride gas.

Hydrochloric acid can be obtained by:

a) Hydrogen burning in chlorine as well ad the dissolving of hydrogen chloride:
H2 Cl2 ==> 2HCl

b) Operation of sulfuric acid to sodium chloride (two stage reaction):
NaCl H2SO4 ==> NaHSO4 HCl
NaHSO4 NaCl = (temp.) => Na2SO4 HCl

Molecular formula:

Description of the reaction equation:
H 2 Cl 2 = 2 HCl
One molecule of chlorine reacts with one molecule of chlorine to give 2 molecules of hydrogen chloride
HCl (g) --- --- HCl H2O (c)
