Hydrogen chloride gas and hydrochloric acid have the same chemical formula: HCl. The difference between the two is that hydrogen chloride is a gas, and hydrochloric acid is an aqueous solution. In HCl(g), the hydrogen atom shares two electrons with the chlorine atom. When this gas is bubble...
Electrolysis of salt solution to produce caustic soda by-product method Electrolysis of salt (sodium chloride) solution produces chlorine gas on the anode and hydrogen gas on the cathode. After washing with water, compressed alkaline washing, freezing and drying, hydrogen with a purity of 99.8% ...
1.(Elements & Compounds) a colourless pungent corrosive gas obtained by the action of sulphuric acid on sodium chloride: used in making vinyl chloride and other organic chemicals. Formula: HCl 2.(Elements & Compounds) an aqueous solution of hydrogen chloride; hydrochloric acid ...
At normal pressure and temperature, hydrogen chloride, a gas composed of the elements hydrogen and chlorine, is a gas. Hydrochloric acid is the name given to a gaseous solution in water. Hydrogen gas and chlorine gas can be combined directly to generate hydrogen chloride; the process is quick...

The same effect is observed with bromine and to a lesser extent with chlorine.3 As already pointed out by Hinshelwood and Williamson,3 the effect is readily explained by chain-breaking reactions of the halogens and their compounds. This may be illustrated by the following well-known reactions:...
Davy, in his original work on HCl, suggested that chlorine, being electronegative like oxygen, was the true acidifying principle in that compound. 戴维在他关于HCl的原始著作中提出,氯与氧一样具有负电性,是该化合物的真正酸化原理。 Later, in his studies on iodine and fluorine compounds, he attribut...
At standard temperature and pressure, hydrogen (H2) is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2. Product Parameters 2. Physical properties Commodity Molecular Formula CAS No. UN No. Hazardous Class Standard Packa...
The formula HCl is often used to refer, somewhat misleadingly, to hydrochloric acid, an aqueous solution that can be derived from hydrogen chloride. Hydrogen chloride is composed of diatomic molecules, each consisting of a hydrogen atom H and a chlorine atom Cl connected by a covalent single ...
