What is a Hydrochloric acid (HCl)?

Hydrochloric acid (HCl) is an inorganic acid composed of hydrogen (H) and chlorine (Cl). It is a colorless or pale yellow liquid with a characteristic pungent odor and is highly acidic. Hydrochloric acid readily dissolves in water and is one of the most widely used chemicals in various industries. Uses include metal cleaning, dissolving, salt production, pH adjustment, and pharmaceutical manufacturing. It is also a major component of stomach acid, playing an essential role in digestion.

Safety is a significant concern, as hydrochloric acid is highly corrosive and poses a serious danger to the skin, eyes, and respiratory system. Inhalation or ingestion can be harmful, so it is crucial to handle it with proper protective equipment and in well-ventilated areas. High concentrations of hydrochloric acid are particularly hazardous, requiring careful handling.
