Gas Introduction
Hydrogen chloride, with the chemical formula HCl, is a colorless gas with a pungent odor composed of one chlorine atom and one hydrogen atom. Its aqueous solution is called hydrochloric acid, also known as hydrochloric acid. Hydrogen chloride is highly soluble in water, and at 0 ℃, one volume of water can dissolve approximately 500 volumes of hydrogen chloride.
Hydrogen chloride, a corrosive non combustible gas that does not react with water but is easily soluble in water, often exists in the form of hydrochloric acid mist in the air. Easy to dissolve in ethanol and ether, and also soluble in various other organic compounds; Easy to dissolve in water, at 25 ℃ and 1 atmosphere, 1 volume of water can dissolve 503 volumes of hydrogen chloride gas. The chemical properties of dry hydrogen chloride are very inactive. Alkali metals and alkaline earth metals can burn in hydrogen chloride, while sodium emits a bright yellow flame when burned.
The aqueous solution of hydrogen chloride is hydrochloric acid. Industrial hydrochloric acid often appears slightly yellow, mainly due to the presence of ferric chloride. Ammonia water is commonly used to detect the presence of hydrochloric acid. Ammonia water reacts with hydrogen chloride to produce white ammonium chloride particles. Hydrogen chloride has a strong dipole and forms hydrogen bonds with other dipoles.
