hydrogen chloride (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A solution of the gas in water is called hydrochloric acid. Because of its great solubility, the gas fumes in moist air.
What is HCl used for?
Hydrogen chloride has many uses, including cleaning, pickling, electroplating metals, tanning leather, and refining and producing a wide variety of products. Hydrogen chloride can be formed during the burning of many plastics. Upon contact with water, it forms hydrochloric acid.
What is HCl structure?
Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar.
What are the chemical properties of HCl?
HCl is an uncoloured gas and has a pungent aroma.
- HCl is an uncoloured gas and has a pungent aroma.
- Hydrochloric acid is the aqueous solution of hydrogen chloride.
- HCl is soluble in water.
- It liquefies at 189K to form a colourless liquid and freezes at 159k to form a white solid.
What is the concentration of HCl?
Hydrochloric acid (HCl) is supplied commercially at concentrations mainly within the range 28–36% w/w.
What is the full form HCl?
On 11 August 1976, the company was renamed Hindustan Computers Limited (HCL).
What is the nature of HCl?
Hydrogen chloride is represented by the chemical formula HCl. This means that a molecule of hydrogen chloride contains one atom of hydrogen and one atom of chlorine. At room temperature (about 77°F [25°C]) and at a pressure of one atmosphere, hydrogen chloride exists as a gas.
How is HCl molecule formed?
When hydrogen chloride is dissolved in water HCl is formed. It is a simple diatomic molecule. The hydrogen and chlorine atom are connected with a single covalent bond. The bond between them is polar as the chlorine atom is more electronegative when compared with the hydrogen atom.
How do you identify HCl?
The easiest way to test for hydrochloric acid is with silver nitrate solution. Add silver nitrate solution to the test solution in a test tube and observe the reaction. If a white precipitate forms, hydrochloric acid is present.
What is the physical state of HCl?
At room temperature, hydrogen chloride is a colorless to slightly yellow, corrosive, nonflammable gas that is heavier than air and has a strong irritating odor.
How do you calculate HCl?
Step 3: Calculate the concentration of hydrochloric acid in mol/dm 3
- Concentration in mol/dm 3 =
- Concentration in mol/dm 3 =
- = 0.125 mol/dm 3
- Relative formula mass of HCl = 1 + 35.5 = 36.5.
- Mass = relative formula mass × amount.
- Mass of HCl = 36.5 × 0.125.
- = 4.56 g.
- So concentration = 4.56 g/dm 3
What is a HCl file format?
HCL is intended as a base syntax for configuration formats built around key-value pairs and hierarchical blocks whose structure is well-defined by the calling application, and this definition of the configuration structure allows for better error messages and more convenient definition within the calling application.
What is the use of HCl?
HCL is a toolkit for creating structured configuration languages that are both human- and machine-friendly, for use with command-line tools. Although intended to be generally useful, it is primarily targeted towards devops tools, servers, etc. NOTE: This is major version 2 of HCL, whose Go API is incompatible with major version 1.
What is the formula for hydrochloric acid (HCl)?
Hydrochloric acid PubChem CID 313 Structure Find Similar Structures Chemical Safety Laboratory Chemical Safety Summary (LCSS Molecular Formula HCl or ClH Synonyms hydrochloric acid hydrogen chloride 7647
What is the percentage of hydrochloric acid in water for analysis?
Hydrochloric acid, for analysis, 25% solution in water Hydrochloric acid, pure, fuming, 37% solution in water
