Hydrochloric acid is a strong, corrosive acid with the chemical formula HCl, commonly used in various industrial processes and found in gastric acid in the human stomach.General OverviewHydrochloric acid (HCl), also known as muriatic acid or spirit of salt, is an aqueous solution of hydrogen chloride. It is a colorless liquid with a pungent odor and is classified as a strong acid due to its complete dissociation in water, making it a powerful reagent in both industrial and laboratory settings.Properties

• Chemical Formula: HCl
• Strong Acid: Hydrochloric acid shows high acidity in solution, typically having a pH of less than 1 for concentrated solutions.
• Physical Properties: It is a colorless to slightly yellow liquid that emits strong fumes of hydrogen chloride when exposed to air. It is highly corrosive, affecting metals, skin, and other materials 2.
