Hydrochloric acid (HCl), commonly referred to as muriatic acid, is a strong, yellow acidic compound characterized by a pungent odor. It is essentially an aqueous solution of hydrogen chloride gas. This versatile chemical is utilized extensively in various industrial applications, including the production of phosphoric acid, chlorine dioxide, ammonium chloride, fertilizers, dyes, and artificial silk, along with pigments for paints. Additionally, it serves as a refining agent in the extraction of metals such as tin and tantalum, functions as a laboratory reagent, and acts as a metal treatment agent. In practical applications, hydrochloric acid is employed to remove scale and debris from boilers and heat exchangers, cleanse membranes in desalination facilities, enhance oil well productivity, prepare synthetic rubber products through the treatment of isoprene, and to clean and prepare metals for coating processes.
