1. Chemical Uses of Hydrochloric Acid

2. Introduction 
Hydrochloric acid, also known as hydrogen chloride or muriatic acid, is an odourless and colourless solution that absorbs hydrogen chloride in water.
It is a poisonous, corrosive and hazardous liquid that, when combined with metals, forms explosive hydrogen gas inducing severe burns and irritation of the eyes.  This highly corrosive chemical compound can be toxic as well.
Production of Hydrochloric Acid
Industrially hydrochloric acid is usually prepared by dissolving hydrogen chloride in water. Hydrogen chloride can be generated in many ways, and thus several precursors to it exist.  Today, hydrochloric acid is primarily manufactured in solutions up to 38 per cent concentrated grade. Higher concentrations up to over 40 per cent are chemically possible, but the evaporation rate is so high that storage and handling require pressurisation and cooling. Bulk industrial-grade product is, therefore, 30 per cent to 35 per cent optimised to balance transport efficiency and product loss through evaporation.

3. Uses of Hydrochloric Acid
Known as a 'workhouse chemical, ' hydrochloric acid has an enormous scope of application in chemical synthesis. 
Production of Inorganic Compounds
This acid is used to prepare compounds like ferric acid, poly aluminium chloride (PAC), iron(III) chloride and aluminium carbohydrate, which are used in treating water.  
Good-quality hydrochloric acid is used in the renewal of ion exchange resins. Cation exchange is extensively used to remove ions such as Na+ and Ca2+ from aqueous solutions, producing demineralised water. The acid is used for flushing the cations from the resins. Akin to its use for pickling, hydrochloric acid is used to dissolve many metals, metal oxides and metal carbonates.
Synthesis of Organic Compounds
Hydrochloric acid synthesises organic compounds like bisphenol A, vinyl chloride, polyvinyl chloride and dichloromethane. These organic compounds have high commercial significance and are used in the plastic industry.

4. Removing Metal Stains and Cleaning Stone and Tiles
Hydrochloric acid is used for bleaching clothes and processing leather in the leather tanning industry. It removes rust from metals like iron and copper in a diluted form.
Purification of Table Salt and pH Control
Hydrochloric acid suppliers in uae  is used to purify table salts and to regulate the acidity (pH) of solutions. It is also used in controlling the pH of food, water and pharmaceutical products.
Oil Production
This compound is injected into rocks to create large-porous structures that mainly assist oil production.
Aqua Regia
Aqua regia is a yellow fuming liquid used for cleaning and making jewellery. This solution is prepared by mixing nitric acid and concentrated hydrochloric acid in a ratio 1:3 ratio. The solution can dissolve noble metals like gold and platinum.
Deionisation
Of the six strong mineral acids in chemistry, hydrochloric acid is the least likely to undergo oxidation. Despite its acidity, it is one of the least hazardous strong acids to handle. 

5. Titration
Medium-strength hydrochloric acid solutions are pretty stable upon storage and maintain their concentration. In addition, the fact that it is available as a pure reagent makes this acid a suitable acidifying compound. 
Chemstock , Hydrochloric acid is the favoured acid in titration for determining the number of bases. Strong acid titrants give more precise results due to a more distinct endpoint. Azeotropic or constant-boiling hydrochloric acid (roughly 20.2 per cent) can be used as a primary standard in quantitative analysis. However, its exact concentration depends on the measured atmospheric pressure when it is prepared.
Sugar Purification
The acidic chemical is also applied in the purification of sugar. Following the removal of xylose and glucose by acid hydrolysis of sugarcane juice, the rest of the organic substances in the solution are removed by hydrochloric acid.
Rate of Reaction
Hydrochloric acid can be used to measure the rate of reaction of sodium thiosulphate.
