The concentration of industrial hydrochloric acid (HCl) varies depending on the application and industry. Commonly, industrial hydrochloric acid is sold in concentrations ranging from 30% to 38%, although it can be concentrated further in certain cases.
38% HCl is a typical concentration for general industrial uses such as metal pickling, chemical production, and pH control.
Concentrated solutions above 38%, sometimes reaching azeotropic levels (around 40%), can also be produced under controlled conditions for specific applications.
Concentrations of 30% to 38%: This is the most common concentration range for industrial hydrochloric acid, used in applications such as metal pickling, chemical production and pH adjustment.
Azeotropic concentrations (~37-40%): In some cases, hydrochloric acid is concentrated to azeotropic levels, which means it cannot be further concentrated by simple distillation. These high concentrations are typically used in specialized industrial processes.
Concentrated Hydrochloric Acid (above 38%): Some industries require higher concentrations of hydrochloric acid, in which case it needs to be handled with care as it is highly corrosive.
