Hydrochloric Acid 33% (HCl) is a strong, highly corrosive acid used in water treatment for pH adjustment, scale removal, and metal cleaning. It appears as a clear, colorless to slightly yellow liquid with a pungent odor. HCl is essential for neutralizing alkaline water, regenerating ion exchange resins in water softeners, and removing deposits from industrial equipment. Due to its high reactivity, it must be handled with caution using appropriate safety measures.
