What is hydrochloric acid (HCl)?
What is Hydrochloric Acid? Hydrogen chloride acid is a colorless, corrosive, liquid that fumes in air at high concentrations of 25% or more, and becomes a hydrogen chloride gas forming dense white vapors due to condensation with atmospheric moisture. The vapor is corrosive, and air concentrations above 5 ppm can cause irritation.

After the year 2000, hydrochloric acid is mostly made by absorbing by-product hydrogen chloride from industrial organic compounds production. Hydrochloric acid is the salt of the protonated water and chloride. Its ions are often written as H 3 O + Cl −, although the cation is in fact often bonded to other water molecules.

How much HCl is in industrial grade?
Industrial market. Hydrochloric acid is produced in solutions up to 38% HCl (concentrated grade). Higher concentrations up to just over 40% are chemically possible, but the evaporation rate is then so high that storage and handling require extra precautions, such as pressurization and cooling.
What is the process of making soda ash?

Does hydrochloric acid kill bacteria?
Not many people are aware of the naturally occurring form of hydrochloric acid produced by the lining of the stomach, that breaks down connective tissue and cell membranes in the food, so that it can more easily be acted on by digestive enzymes. Hydrochloric acid also kills most of the bacteria ingested with the food.

Inhalation of hydrochloric acid vapors and mists produces nose, throat, and laryngeal burning, and irritation, pain and inflammation, coughing, sneezing, choking sensation, shortness of breath, hoarseness, laryngeal spasms, upper respiratory tract edema, bronchial constriction, bronchitis, chest pains, as well has headache, and palpitations. Inhalation of high concentrations can result in corrosive burns, necrosis of bronchial epithelium, constriction of the larynx and bronchi, nasospetal perforation, glottal closure, occur, particularly if exposure is prolonged. May be fatal if inhaled.

History
In the early tenth century, the Persian physician and alchemist Abu Bakr al-Razi (c. 865–925, Latin: Rhazes) conducted experiments with sal ammoniac (ammonium chloride) and vitriol (hydrated sulfates of various metals), which he distilled together, thus producing the gas hydrogen chloride. In doing so, al-Razi may have stumbled upon a primitive method for producing hydrochloric acid, as perhaps manifested in the following recipe from his Kitāb al-Asrār ("The Book of Secrets"):
Structure and reactions
Hydrochloric acid is the salt of the protonated water and chloride. Its ions are often written as H3O Cl , although the cation is in fact often bonded to other water molecules. A combined IR, Raman, X-ray, and neutron diffraction study of concentrated hydrochloric acid revealed that the primary form of H (aq) in these solutions is H5O2 , which, along with the chloride anion, is hydrogen-bonded to neighboring water molecules in several ways. (See Hydronium for further discussion o…

Applications
Hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality. Hydrogen chloride, not hydrochloric acid, is used more widely in industrial organic chemistry, e.g. for vinyl chloride and dichloroethane.
One of the most important applications of hydrochloric acid is in the pickling of steel, to remove r…
Presence in living organisms
Gastric acid is one of the main secretions of the stomach. It consists mainly of hydrochloric acid and acidifies the stomach content to a pH of 1 to 2. Chloride (Cl ) and hydrogen (H ) ions are secreted separately in the stomach fundus region at the top of the stomach by parietal cells of the gastric mucosa into a secretory network called canaliculi before it enters the stomach lumen.
