Hydrochloric Acid (HCL) is a highly corrosive, strong mineral acid composed of hydrogen chloride dissolved in water. It is a clear, colorless to slightly yellow liquid with a pungent, irritating odor. Widely used in industrial, laboratory, and chemical manufacturing processes, HCL plays a vital role in metal cleaning, pH control, pickling of steel, and production of organic compounds. In the human body, hydrochloric acid is naturally produced in the stomach to aid digestion by breaking down food and killing harmful bacteria. Key Properties: Chemical formula: HCl Appearance: Clear, colorless liquid pH: Highly acidic (pH < 1) Uses: Industrial cleaning, chemical synthesis, food processing, pharmaceuticals
