Hydrochloric Acid 33% which belongs to the category of strong acids, is a colorless, clear liquid with a very pungent odor and is highly corrosive. This acid, as its name implies, is Chlorine-based and is a solution of Hydrogen Chloride, water and other additives such as Hydronium and chlorine ions. It is a monoprotic acid and in each reaction, each molecule is able to release only one chloride ion (Cl-) and one hydrogen ion (H+).

Hydrogen ions can react with water to produce Hydronium ions (H3O+). Chloride ions can also produce Sodium Chloride (NaCl) in response to compounds that contain sodium ions.

HCL as a strong and mineral acid has many applications in various industries.

  • Acidification of oil wells
  • Detergents
  • Production of organic and inorganic compounds
  • PH control and neutralization
  • Revival of ion exchangers
  • Preparation of ethylene dichloride
  • Manufacturing a variety of chemicals and food processes
  • Neutralization of alkaline compounds or metal scrap
  • Leather polishing
  • Water treatment
  • Cosmetics and pharmaceutical industries
  • Acid washing in the steel industry

Ion exchangers

Ion exchangers (Hydrochloric Acid is composed of H+ and Cl- ions, which ions can move in reactions) are widely used in many reactions. For example, using a cation ion exchanger, ions such as Na+ and Ca2+ can be removed from aqueous solutions to produce pure water. Hydrochloric Acid 33% can be used in the chemical industry, drinking water production and many food industries.

PH control or neutralization

Hydrochloric Acid is widely used in regulating the acidity of solutions (depending on the purity) of drinking water, medicine and food, neutralizing and sanitizing pool water. Hydrochloric Acid 33% is used to regulate the pH in water treatment, cosmetics and health industries.

Use of Hydrochloric Acid 33% in the steel industry

One of the most important and necessary steps in preparing the steel surface before using it in processes such as extrusion, rolling, galvanizing, is to remove iron rust (iron oxide) from its surface. HCL 33% can be used to do this, which is called acid washing.

Production of inorganic compounds

Many products can be obtained from Acid–base reaction. Iron (III) ‌Chloride (Ferric Chloride, FeCl3) and Polyaluminum Chloride (PAC) can be obtained in reactions using Hydrochloric Acid. Both compounds are used in wastewater treatment, drinking water production and paper production. Other inorganic compounds that can be produced using this acid include Calcium Chloride, Nickel(II) Chloride, and Zinc Chloride.

Other applications

Other uses of HCL include leather polishing, house cleaning, building construction and food additives. This acid is also used in production of drilling fluids.


Safety tips

Hydrochloric Acid produces acid vapors at high concentrations. Both acid vapor and its solution are harmful to organs and tissues. This acid has the power to damage the respiratory system, eyes, skin and intestines. The combination of HCL with oxidizing chemical compounds such as Sodium Hypo (NaOCl), produces the toxic chlorine gas. In order to minimize the risks, it is necessary to do the following:

  • Use plastic gloves or PVC gloves
  • Use protective glasses
  • Wear chemical resistant clothing
  • Have proper ventilation in the place of storage and use
