Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
His improvements to chemical processes and equipment (notably furnaces and distillation devices [4]) make him an early chemical engineer. [ 1 ] He was the first to produce concentrated hydrochloric acid in 1625 by combining sulfuric acid and table salt.
As a highly corrosive liquid, hydrochloric acid should be handled only with appropriate safety precautions. Hydrochloric acid, or muriatic acid by its historical but still occasionally used name, has been an important and frequently used chemical from early history, and was discovered by the alchemist Jābir ibn Hayyān around 800.
Carl Wilhelm Scheele (German:, Swedish: [ˈɧêːlɛ]; 9 December 1742 – 21 May 1786 [2]) was a German Swedish [3] pharmaceutical chemist.. Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, nitrogen, and chlorine, among others.
In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid.
Hydrochloric acid, a solution of hydrogen chloride in water; Hydrochloride, the salt of hydrochloric acid and an organic base; Hydrogen chloride, chemical formula HCl; Hypomania Checklist, a questionnaire used to screen for hypomania and bipolar spectrum disorders; HCL color space, a color space model designed to accord with human perception of ...
An acidic solution — generally hydrochloric acid — is used to separate the gold from the carbon. The gold-laden liquid is poured over electrified steel, which attracts flakes of the metal. Heavy metals are a byproduct of refinement. In 2000, a cask of mercury leaked in transit from the Yanacocha mine, sickening nearly 1,000 people.
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.
