chlorwasserstoffsäure

Chlorwasserstoffsäure, also known as hydrochloric acid, is a colorless solution of hydrogen chloride gas in water. It is a strong acid with the chemical formula HCl. It is produced industrially by several methods, including the direct synthesis of hydrogen and chlorine gas, and as a byproduct of chlorination reactions. Hydrochloric acid is highly corrosive and can cause severe burns upon contact with skin and damage to metals. Its high acidity makes it useful in many industrial processes, such as metal pickling, the production of chemicals, and pH regulation. In biology, hydrochloric acid is a key component of gastric juice in the stomach of animals, where it aids in digestion by denaturing proteins and activating pepsin. It is also found in certain geological formations. Due to its corrosive nature, proper safety precautions are essential when handling chlorwasserstoffsäure, including the use of protective clothing, gloves, and eye protection. Storage should be in well-ventilated areas in corrosion-resistant containers.
