Hydrochloric Acid

An aqueous solution of hydrogen chloride is what is known as hydrochloric acid, commonly referred to as muriatic acid. It has an unmistakably strong odour and is colourless. It is categorized as a powerful acid. In the digestive tracts of the majority of animal species, including humans, it is a part of the stomach acid. A crucial industrial chemical and reagent for laboratories is hydrochloric acid.

Hydrochloric Acid Formula

The Chemical Formula of Hydrochloric Acid is HCl. Hydrochloric Acid molecule contains one atom of Hydrogen and one atom of Chlorine, hence its Chemical Formula is HCl.

Hydrochloric Acid Chemical Formula

The chemical formula for hydrochloric acid is HCl. It consists of one hydrogen atom (H) bonded to one chlorine atom (Cl).

HCL Chemical Name

HCL typically stands for “Hydrochloric Acid.” Its chemical formula is HCl, representing a strong acid composed of one hydrogen atom (H) and one chlorine atom (Cl). Hydrochloric acid is a corrosive and highly reactive chemical commonly used in various industrial and laboratory applications. It’s also found naturally in the human stomach, where it plays a crucial role in digestion.

Hydrochloric Acid HCL Density

The substance’s mass per unit of volume is known as its density (volumetric mass density or specific mass). The Density of Hydrochloric Acid (HCl) is 1.2 g/mL at 25 °C.

Hydrochloric Acid Uses

Strong inorganic acid hydrochloric acid is employed in numerous industrial operations, including the refinement of metal. The desired product quality is frequently determined by the application. In industrial organic chemistry, hydrogen chloride rather than hydrochloric acid is utilized more frequently.

Pickling of steel

In order to remove rust or iron oxide scale from iron or steel before undergoing further processing, such as extrusion, rolling, galvanizing, and other methods, pickling steel is one of the most significant uses of hydrochloric acid. The most used pickling agent for carbon steel grades is technical quality HCl, which is typically 18% concentrated.

Production of inorganic compounds

Hydrochloric acid is used to dissolve a variety of metals, metal oxides, and metal carbonates, similar to how it is used for pickling. Simplified formulae are frequently used to represent the conversion:

Zn + 2 HCl → ZnCl₂ + H₂
NiO + 2 HCl → NiCl₂ + H₂O
CaCO₃ + 2 HCl → CaCl₂ + CO₂ + H₂O

pH control and neutralization

Using hydrochloric acid, you may control the pH (acidity) of your solution.

Regeneration of ion exchangers

Ion exchange resin regeneration uses top-notch hydrochloric acid. The process of demineralizing water by removing ions like Na⁺ and Ca₂⁺ from aqueous solutions is known as cation exchange. The cations are removed from the resins using the acid.

Laboratory use

The hydrochloric acid is the monoprotic acid that is least likely to have an interfering oxidation-reduction process among the common strong mineral acids used in chemistry. Despite its acidity, it contains the non-reactive and non-toxic chloride ion, making it one of the least dangerous strong acids to work with. Solutions of intermediate grade hydrochloric acid are quite stable when stored and retain their concentrations over time.

Hydrochloric Acid vs Hydrofluoric Acid

The main distinction between hydrofluoric acid and hydrochloric acid is that the latter is a strong acid while the former is a mild acid. Additionally, hydrofluoric acid has the ability to generate hydrogen bonds, whereas hydrochloric acid is unable to do so.

Hydrochloric Acid	Hydrofluoric Acid
1. Aqueous hydrogen chloride is hydrochloric acid.	1. Hydrogen fluoride dissolved in water is hydrofluoric acid.
2. Hydrochloric Acid has molar mass 36.5 g/mol	2. Hydrofluoric Acid has molar mass 20 g/mol.
3. It is a strong acid, and it cannot form hydrogen bonds.	3. It is a weak acid, and it can form hydrogen bonds.
4. Hydrochloric acid molecule has a chloride ion	4. Hydrofluoric acid molecule has a fluoride ion

FAQs

What are hydrochloric acids used for?

In the food, textile, metal, and rubber sectors, hydrogen chloride (HCl) is frequently employed as a bleaching agent to neutralise alkaline substances. When discharged into the soil, it is neutralized, and when it comes into contact with water, it hydrolyzes quickly.

Is hydrochloric acid harmful to humans?

Chemical burns from hydrochloric acid can be extremely painful if they come into contact with skin or other tissues. Ingestion of hydrochloric acid might result in blindness. The amount of acid used and how long it stays in contact with the tissues determine how severe the burns are.

What is an example of hydrochloric acid?

Domestic cleaners Due to its corrosive qualities that aid in removing stubborn stains, hydrochloric acid can be a component of household cleaners like toilet bowl cleaners, bathroom tile cleaners, and other porcelain cleaners.

Which acid can burn skin?

When hydrofluoric acid is present in high quantities (> 50%), it behaves as a potent acid that, when in direct contact with the skin, eyes, respiratory system, and gastro-intestinal mucous membrane, results in corrosive burns.
