Answer:
Hydrochloric Acid
Hydrochloric acid (HCl, also known as muriatic acid) is a colorless corrosive, strong mineral acid with many industrial uses among which, when it reacts with an organic base it forms a hydrochloride salt. Hydrochloric acid was historically produced from rock salt and green vitriol and later from the chemically similar common salt (NaCl) and sulfuric acid:
2NaCl+H2SO4→2HCl+Na2SO4
Hydrochloric acid is a versatile chemical that hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of vinyl chloride (CH2CHCl) for PVC plastic, and polyurethane. It has numerous other industrial uses such as (i) hydrometallurgical processing, for example, production of alumina and/or titanium dioxide; (ii) chlorine dioxide synthesis; (iii) hydrogen production; (iv) activation of petroleum wells; (v) miscellaneous cleaning/etching operations including metal cleaning (e.g., steel pickling); and (vi) being used by masons to clean finished brick work. In the context of this book, the term hydrogen chloride is used to describe the gaseous form while the term hydrogen acid is used to describe a solution of hydrogen chloride in water.
Hydrochloric acid may be manufactured by several different processes; however, most of the hydrochloric acid (hydrogen chloride) produced in the United States is a by-product of the chlorination reaction. After leaving the chlorination process, the gas stream containing hydrogen chloride proceeds to the absorption column, where concentrated liquid hydrochloric acid is produced by absorption of hydrogen chloride vapors into a weak solution of hydrochloric acid. The hydrogen chloride-free chlorination gases are removed for further processing. The liquid acid is then either sold or used elsewhere in the plant. The final gas stream is sent to a scrubber to remove the remaining hydrogen chloride prior to venting.
In the chlor-alkali industry, brine solution (a mixture of sodium chloride and water) is electrolyzed to produce chlorine (Cl2), sodium hydroxide, and hydrogen (H2):
Answer:
it's not true for all the reactions taking place on earth for an example a titration may involve hydrochloric acid but paper industry and and food industry does not involve hydrochloric acid
