Hydrochloric acid - HCl

What is Hydrochloric acid?

Hydrochloric acid is an inorganic chemical. It is a strong corrosive acid with a chemical formula HCl. It is also known as hydrogen chloride or muriatic acid. When hydrogen chloride is dissolved in water HCl is formed. It is a simple diatomic molecule. The hydrogen and chlorine atom are connected with a single covalent bond. The bond between them is polar as the chlorine atom is more electronegative when compared with the hydrogen atom. It is strongly acidic. It is colorless and viscous. It is corrosive and has a distinctive pungent smell. It is widely used as a laboratory reagent and industries. It is used in the processing of leather, production of gelatin. The physical properties such as density, melting point, PH, boiling point depends on the molarity or concentration of HCl.
