One of the major products of the chemical industry is hydrochloric acid (hydrochloric acid). The method of preparation of this acid is similar to that of nitric acid. Hydrochloric acid is a mixture of hydrogen chloride in water. It is a highly corrosive substance and a strong mineral acid, and for this reason it has many applications in industry. The production of large quantities of this acid is usually dependent on the production of other industrial and chemical materials.
