Hydrogen chloride forms corrosive hydrochloric acid on contact with water found in body tissue. Inhalation of the fumes can cause coughing, choking and inflammation of the nose, throat, and upper respiratory tract, and in severe cases, pulmonary edema, circulatory system failure, and death. Skin contact can cause redness, pain, and severe skin burns. Hydrogen chloride may cause severe burns to the eye and permanent eye damage.
Hydrogen chloride is made up of a hydrogen atom and a chlorine atom, whereby the atoms share their valence electrons, thus they are joined by covalent bonds. A hydrogen atom has 1 valence electrons while a chlorine atom has7, and in order to obtain a stable structure, the hydrogen atom has to share 1 electron with the chlorine atoms After that, the hydrogen atom would have acquired the electronic configuration of 2 (, while the chlorine atom would have acquired the electronic configuration of 2.8.8
