Chemical database: 3. Hydrochloric acid

Hydrochloric acid is a strong inorganic acid, with strong corrosive properties. Along with sulphuric acid, it is one of the most important inorganic acids in the industry. Density = 1.18 g/cm3. Melting point = -27.32°C. Boiling point = 48°C. One of the primary uses of this acid is the production of vinyl chloride, which is used in PVC manufacturing. It also has many applications in smaller quantities: household cleaning, production of food additives, leather processing, synthesis of many substances, steel processing, etc.

Hydrochloric acid can be bought in many usual stores. Directly translated, in Croatia it can be found under the name „salt acid“, but we believe that it can be found as „muriatic acid“ in English speaking countries. It usually comes in various concentrations (mostly around 19%). Solutions of higher concentrations can be ordered from drugstores/pharmacies, or companies that sell chemicals. The price starts around 1.5€ for a liter.
