Hydrochloric acid, known by its alternative name muriatic acid, is a solution of strong inorganic acid with the chemical formula HCl. It is a colorless liquid with a pungent odor that is very corrosive to skin, eyes and metals. History of Discovery. During the 15th century, a German alchemist named VALENTIN applied heat to a substance called ...
Hydrogen chloride is a common synonym for hydrochloric acid. (4) The chemical formula for hydrochloric acid is HCl, and its molecular weight is 36.47 g/mol. (1,3) Hydrochloric acid occurs as a colorless, nonflammable aqueous solution or gas. (1,3,4) Hydrochloric acid has an irritating, pungent odor, with an odor threshold of about 7 mg/m 3. (1)
Jun 4, 2019 · Hydrochloric acid is formed when hydrogen chloride dissolves in water. In this situation, hydrogen chloride, a simple molecule made up of one positively charged hydrogen attached to one negatively charged chlorine, takes little persuading to pull itself apart. Thus, all of its hydrogen is readily ‘donated’.
Jan 24, 2023 · Hydrochloric acid is a strong acid. It behaves as an electrolyte. That is, the water being a polar solvent helps to ionize HCl to give hydronium ( H 3 O +) ions. Due to the presence of such ions, it shows acidic properties, and also makes it a good electrolyte as it conducts electricity. HCl + H 2 O → H 3 O + + C l –. 2.
May 1, 2023 · Hydrochloric acid (HCl), another component of the gastric juice, plays a crucial role in creating the pH required for pepsin activity. Parietal cells produce HCl by secreting hydrogen and chloride ions. When pepsinogen and hydrochloric acid exist together in the gastric juice, pepsin takes its active form.
Apr 20, 2023 · Hydrochloric acid is a strong acid, since it is completely dissociated in water. Hydrochloric acid is the preferred acid in titration for determining the amount of bases and can also be used to prepare various chloride salts. It is often sold under the common name of muriatic acid for applications like cleaning concrete and pools.
