Product Application:  

1. It can maintain the most suitable pH value for activating pepsin in gastric juice. It can also denaturate the protein in salt and make it easy to hydrolyze, and kill the bacteria that enter the stomach with food.  In addition, hydrochloric acid into the small intestine, can promote the secretion of pancreatic fluid, intestinal fluid and bile secretion and discharge, acidic environment also contributes to the absorption of iron and calcium in the small intestine.  

2, the use of hydrochloric acid can react with the nature of insoluble alkali, cleaning toilet spirit, rust remover and other daily necessities.  

3. Hydrochloric acid, as a strong inorganic acid, is widely used in industrial processing, such as metal refining.  Hydrochloric acid often determines the quality of the product.  

4. In analytical chemistry, when acid is used to determine the concentration of a base, hydrochloric acid is generally used for titration.  Titration with strong acid makes the end point more obvious and results more accurate.  At 1 atmospheric pressure, 20.2% hydrochloric acid can form an azeotropic solution, which is often used as a reference material for quantitative analysis at a certain atmospheric pressure.  Its azeotropic concentration varies with the pressure.  

5. One of the most important uses of hydrochloric acid is pickling steel.  Hydrochloric acid may be used to remove rust or iron oxide from the surface prior to subsequent processing of iron or steel (extrusion, rolling, galvanizing, etc.).  Carbon steel is usually cleaned with an 18% hydrochloric acid solution as a pickling agent.  

6. Control pH and neutralize lye;  Used for flame reaction;  For cation exchange resin regeneration and other fields.
