Chlorine Gas Formula

Molecular Formula of Chlorine

Chlorine, abbreviated as Cl, is the second lightest halogen. This chemical element has an atomic number of 17. It takes on the appearance of pale yellow-green gas. Chlorine in liquid form can burn the skin, and chlorine in gaseous form irritates the mucous membrane. It is found between fluorine and bromine on the periodic table. 


What is the Chemical Formula for Chlorine?

[Ne]3s23p5 is its electrical configuration. There are two stable isotopes of chlorine. They are 37Cl and 35Cl, respectively. The stable radioisotope of chlorine is 36Cl. The most common chlorine chemical is sodium chloride, while hydrogen chloride is the simplest. The molecular formula of sodium chloride is NaCl, while the molecular formula of hydrogen chloride is HCl. It has high reactivity.

Chlorine exists in the form of chloride. Do you know the chemical formula of chloride? Chloride is represented as Cl- and hence Cl- is chloride formula.

On this page, we will study the chlorine formula in detail.


Chlorine Gas Formula and Structure 

Chlorine gas has the chemical structure Cl2 and has a molecular weight of 70 g/mol. Cl-Cl, commonly known as the element form of chlorine, has a structure that consists of two chlorine atoms connected by a covalent connection. Both atoms have an sp3 orientation, which means they have a tetrahedral structure. In the typical representations for organic compounds, its chemical structure can be expressed as follows.

The chlorine gas formula structure is shown above.


Occurrence

Although chlorine gas is extremely reactive, the chlorine ion is abundant in nature, particularly in the form of inorganic salts such as NaCl.


Preparation of Chlorine

The Chlor-alkali process, in which a solution of NaCl is electrolytically dissolved by the application of a current, produces hydrogen gas, chlorine gas, and sodium hydroxide. It is one technique of producing chlorine gas.

2 NaCl + 2 H2O → Cl2 + H2 + 2 NaOH

Because sodium chloride is taken from salt water, lakes, or mineral sources, this procedure is inexpensive.

A second approach involves combining hydrochloric acid with manganese dioxide to produce chlorine.


Properties of Chlorine

Physical Properties:

Cl2 is the chlorine formula. Its colour is yellow-green, and its odour is comparable to that of household bleach. It is water-soluble and interacts with water to create hypochlorous and hydrochloric acids.

Chlorine Chemical formula- Cl2

Molecular weight- 70.906 g/mol

Density- 3.2 g/lt

Melting point- -101.5 °C

Boiling point- -34.038°C

Chlorine is a stifling greenish-yellow gas with a foul odour. It liquefies around 35°C and is water soluble to a degree. It's sold as compressed liquefied gas.


Chemical Properties:

Many of the properties of chlorine gas are similar to those of elemental chlorine. It is the most basic form of the chlorine element, due to the [Ne]3s23p5 configuration of the chlorine atom, which is too unstable to survive as an isolated species. However, when two chlorine atoms form a bond, they share one electron, resulting in the electronic configuration [Ar], which is considerably more stable.


Applications of Chlorine

  1. Because of its disinfecting characteristics, chlorine gas is employed in water treatment. It is used as a bleaching agent in the paper industry.

  2. Chlorine gas is an inorganic gas that is utilised in controlled quantities in the chemical industry. It is controversial because it has been used in chemical weapons.

  3. Because of its non-metallic behaviour, this diatomic molecule is very reactive and has a high electronegativity. It's a halogen, and the most well-known chemical is sodium chloride (NaCl). Table salt is made up of sodium chloride (NaCl). It's a common bleaching agent used to keep viruses and germs out of drinking water. It's also used in dyes, pharmaceuticals, and the automobile and agriculture industries.


Health Hazards

When vinegar is concentrated, it is extremely hazardous to one's health and can be lethal if inhaled. It irritates the eyes and causes skin discomfort. Because it is a strong oxidising agent, it can potentially cause a fire. Aquatic life is poisoned by it. When chlorine gas in high concentrations comes into contact with the skin, it causes significant irritation and tissue destruction. Burning, blistering, and prickling sensations are all possible symptoms. It produces serious burns when it comes into contact with the eyes. Because it is exceedingly poisonous, inhaling high doses of this gas produces unconsciousness.


Conclusion

The second lightest halogen is chlorine, abbreviated as Cl. It takes on a pale yellow-green gas look. Chlorine burns the skin when it is liquid, and chlorine irritates the mucous membrane when it is gaseous. The chlorine gas formula is Cl2. Chlorine gas is an inorganic gas that is utilised in controlled quantities in the chemical industry. It is controversial because it has been used in chemical weapons. It's a halogen, and the most well-known chemical is sodium chloride (NaCl)

FAQs (Frequently Asked Questions)

Q1. Is it Chlorine (Cl) or Chlorine (Cl2)?

Ans. One molecule of chlorine gas has the formula Cl2. Chlorine has only one chemical symbol: Cl. H2, N2, O2, Cl2 are diatomic molecules that exist in gases such as hydrogen, nitrogen, oxygen, and chlorine. One molecule of gas, such as Cl-Cl, has two atoms bonded by a covalent bond.

Q2. What is the Formula of Chloride? What Is a Typical Level of Chloride in the Body?

Ans. 96 to 106 milliequivalents per litre (mEq/L) or 96 to 106 millimoles per litre (millimol/L) is a common normal range. The normal value ranges may differ slightly between laboratories. Discuss the significance of your specific test results with your healthcare professional.

Q3. What is the Impact of Chlorine on the Human Body?

Ans. Chlorine combines with water to form acids when it enters the body through inhaling, ingesting, or skin contact. The acids are corrosive and cause damage to body cells when they come into touch with them.
