- hydrogen chloride (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid. Hydrogen chloride may be formed by the direct combination of chlorine (Cl 2) gas and hydrogen (H 2) gas; the reaction is rapid at temperatures above 250 °C (482 °F).

May 19, 2024 · Hydrochloric acid gas (HCl gas) is a colorless, poisonous gas with a pungent odor and is highly corrosive. It is composed of hydrogen and chlorine, both halogens. Hydrochloric acid gas is primarily used in industrial settings where it has a variety of applications ranging from chemical synthesis to pH control and metal treatment processes.
May 8, 2024 · Hydrochloric acid (HCl) is a strong acid that completely dissociates in water, releasing hydrogen ions (H+) and chloride ions (Cl-). The concentration of hydrogen ions in an HCl solution is the same as the initial concentration of the acid. For example, in a 0.1 M solution of HCl, the concentration of hydrogen ions is 0.1 M.
May 5, 2024 · Hydrochloric acid (HCl) is a strong acid with a pH value of approximately 1, making it a highly acidic substance. When HCl is added to water, it dissociates completely into hydrogen ions (H+) and chloride ions (Cl-), leading to an increase in hydrogen ion concentration and a decrease in pH.
