History of Hydrochloric Acid

The first references to hydrochloric acid come from the 13th century, in works describing the use of aqua regia as a mixture of nitric and hydrochloric acid. This solution was prepared by mixing sal ammoniac in nitric acid.

A pure solution of hydrochloric acid, however, wasn’t available until the 15th or 16th century, but historians cannot agree who first discovered it. Some say it was Libavus, by heating salt; while others believe it was Benedictine monk Basil Valentine, by mixing salt and vitriol.

During the following centuries, many chemists started to use this acid in their work, including English chemists Joseph Priestly, who prepared pure hydrogen chloride in 1772, as well as Humphry Davy, who finally proved its chemical composition in 1808.


Large-Scale Production of Hydrochloric Acid

During the Industrial revolution, the production of HCl reached large-scale proportions. This was derived from a process to produce sodium carbonate (NaCO3, soda ash) which involved common salt mixed with sulphuric acid, limestone and coal.

This reaction released hydrogen chloride gases as a by-product, which was simply dumped into the atmosphere.

However, environmental concerns led to new legislation written in 1863, forcing all manufacturing plants to absorb this by-product in water, producing unprecedented amounts of hydrochloric acid.

This process was eventually replaced by a hydrochloric acid-free method, but in the meantime, this compound had become a vital chemical in many different industries and continued being produced in large amounts.

What is Hydrochloric Acid?

Hydrochloric acid (HCL) is a clear, colourless and pungent solution created by dissolving hydrogen chloride gas in water. It is a by-product of chlorine manufacture, along with sodium hypochlorite and sodium hydroxide.

Uses for Hydrochloric Acid 

A highly corrosive mineral acid, hydrochloric acid has many industry uses, making it known as a ‘workhorse chemical’. Its uses include:

  • In the production of different types of chlorides and metals
  • In the refinement of ore
  • As a pH regulator in pharmaceuticals and the food industry
  • In the creation of sugars, food additives and gelatin
  • In the removal of rust and scale during steel pickling
Hydrochloric acid is also used on small scale application such as leather processing, household cleaning and building construction. Other names for hydrochloric acid include muriatic acid, chlorohydric acid, marine acid and spirits of salt.

Hydrochloric Acid Hazards 

Hydrochloric acid must be stored in a well-ventilated area away from non-compatible materials and solutions. Skin and eye contact must be avoided at all times; as well as ingestion and/or inhalation. This chemical will corrode metals, rubber and some plastics if allowed to come into contact with them. Please refer to our Material Safety Data sheet (MSDS) for full details on hydrochloric acid safety and storage.
