| Overview | Hydrochloric acid is a strong, corrosive mineral acid commonly used in laboratories and industry. It is a clear, colorless to slightly yellow liquid with a sharp, pungent odor. HCl is widely used for pH control, metal cleaning, chemical synthesis, and water treatment. It is highly reactive and corrosive to skin, eyes, and mucous membranes. Inhalation of vapors can cause severe respiratory irritation. Proper PPE and ventilation are essential when handling. HCl is typically stored in corrosion-resistant containers in cool, well-ventilated areas. |
