[0002] Hydrochloric acid is an aqueous solution of hydrogen chloride, a monobasic inorganic strong acid with a wide range of industrial uses. Hydrochloric acid is a colorless, transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid is extremely volatile, so when a container containing concentrated hydrochloric acid is opened, the hydrogen chloride gas will evaporate and combine with water vapor in the air to produce small droplets of hydrochloric acid, causing acid mist to appear above the bottle mouth. Hydrochloric acid is the main component of gastric acid, which can promote food digestion and resist microbial infection. Contact with hydrochloric acid vapor or smoke can cause acute poisoning, conjunctivitis, burning sensation of the nose and oral mucosa, epistaxis, gingival bleeding, tracheitis, etc. Therefore, waste hydrochloric acid cannot be discharged at will, and hydrochloric acid should be effectively recycled.
