Jabir bin Hayyan discovered hydrochloric acid formula in 800 AD. Hydrochloric acid is an aqueous solution of hydrogen chloride gas, a strong inorganic acid, and the basic component of gastric acid. JC was used to find stone philosophers in the Middle Ages. Later, it taught many European scientists the principles of modern chemistry and then became an important chemist in many applications during the Industrial Revolution. It is used in the production of many organic compounds (such as vinyl chloride). Because it is a highly corrosive liquid, special care must be taken. We will introduce you.
Formula: HCl
Molar mass: 36.46094 g / mol
Structure and properties: refractive index (n), dielectric constant (εr), etc.
Boiling point: depends on the concentration-see table
GHS hazard statement: H290, H314, H335
Melting point: depends on the concentration-see table
It is an inorganic acid called brocade hydro acid or cyanide. Its molecular formula is HCN. The detailed information is expressed in H-CºN. Its molecular weight is equivalent to 27.03 g. CH 4 is synthesized by processing a mixture of NH 3 gaseous ammonia and methane The oxidation method exists and can be prepared in the laboratory by treating sodium cyanide NaCN or potassium cyanurate K 4 Fe (CN) 6 with acid. chemistry analysis
Hydrochloric acid can be a gas or a liquid. In both cases, it has a very weak acidity. The density of a gas is different from the density of a liquid. Liquid, with a melting point of -13.4. It is soluble in water and alkaline solutions and is usually stored in a cool place in a closed brown bottle.
use
It is packed in a bottle in the form of compressed liquid and used in the form of gas when escaping. It has lethal lethality to insects and rodents on the ship and is used as an aqueous solution to spray fruit trees to fight insect reproduction.
It is used as a raw material in the preparation of many organic and inorganic compounds, as well as in the fields of organic synthesis and chemical analysis.
Used in the manufacture of plastics and rubber.
It is used to regenerate resin ion exchangers for activated resins.
Used to remove rust.
In addition to its use in the manufacture of many pharmaceuticals (such as ascorbic acid), it is also used in the production of organic compounds such as vinyl chloride and ethane.
For the production of inorganic compounds.
Used for solution pH adjustment.
