В другом языковом разделе есть более полная статья Hydrochloric acid (англ.) Вы можете помочь проекту, расширив текущую статью с помощью перевода. Hydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride (HCl) in water. It is a highly corrosive, strong mineral acid with many industrial uses. Hydrochloric acid is found naturally in gastric acid. When it reacts with an organic base it forms a hydrochloride salt. Hydrochloric acid is a strong acid, since it is fully dissociated in water. Monoprotic acids have one acid dissociation constant, Ka, which indicates the level of dissociation in water. Hydrochloric acid, abbreviation HCl(aq), is a common acid both in the body and in the lab. It is, for example, a major component of gastric acid (pH 1-2, 0.5% w/v HCl). In experiments, it is used among other things to set the pH in buffers (e.g. Tris) and to reveal antigens (e.g. BrdU). Hydrochloric acid (HCL) is a colorless and highly pungent solution of hydrogen chloride and water. Once commonly referred to as muriatic acid or spirit of salt... Hydrochloric acid is an inorganic acid with the chemical formula of HCl. It is normally an acidic liquid but can be a gas, which gives off a terrible odor. The color of the liquid is normally a clear to yellowish color. It is naturally found within the stomach and its purpose is to break down foods. 2. General Characteristics of Hydrochloric Acid Hydrochloric acid is a non-flammable, transparent and colorless or light yellow liquid. The amount of hydrochloric acid (HCL) administered is based upon base excess (milliequivalent/liter), with an equivalent amount being administered. Hydrochloric or muriatic acid is generally made by the action of sulphuric acid on common salt.
