Hydrochloric Acid

Concentrated hydrochloric acid forms acidic mists that have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes and skin.
Upon mixing hydrochloric acid with common oxidizing chemicals, such as sodium hypochlorite or potassium permanganate, the toxic gas chlorine is produced.
If even a minute quantity of hydrochloric acid, strong or dilute, enters the eyes or if the eyes have been exposed to hydrochloric acid then eyes should be irrigated with running water at least for fifteen minutes.
Shelf Life: Longer life is expected if properly stored in air tight vessel.

HCl acid is used in the preparation of metal chlorides.
In ferrous and non-ferrous metallurgies for removal of oxide film from the metal surface, in metal leaching of ores. In other industries for boilers cleaning and chemical water treatment not related to potable water supply. Hydrochloric acid is used in the production of dyes, drugs, paints, etc. It is used for the production of glucose from starch. It is used for the extraction of glue from bones. It is used as a laboratory reagent.

In bulk it is supplied in Rubber lined and FPR tank trucks. Also supplied in HDPE 35 kg cans and 250 kg drums. Hydrochloric acid must be stored in well-ventilated ware houses.
Do not store it along with caustic soda and other alkaline materials.

  • It reacts with most metals with evolution of hydrogen which may cause fire or explosions with air.
  •   Hydrogen Chloride, both as a gas and in solution form is hydrochloric acid, which is a corrosive substance and can cause severe and painful burns on contact with any part of the body, or if taken internally.
  • The mucous membrane of the eyes and the upper respiratory tract are especially susceptible to the
  • irritating effects of high atmospheric concentration of hydrogen chloride.
