What are physical properties of chlorine?
Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.
What are the properties and uses of chlorine?
A yellowy-green dense gas with a choking smell. Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides.
What are 5 uses of chlorine?
5Uses. Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.
What are the physical properties of sodium chloride?
Physical properties: Sodium chloride is a white crystalline solid with a density of 2.16 g/mL, and a melting point of 801 °C. It is also available as aqueous solutions of different concentrations, called saline solutions. Chemical properties: Sodium chloride is readily soluble in water and other polar solvents.
What is a physical change of chlorine?
Physical properties Chlorine changes from a gas into a liquid at a temperature of -34.05°C (-29.29°F) and from a liquid to a solid at -101.00°C (-149.80°F). The gas is soluble (dissolvable) in water. It also reacts chemically with water as it dissolves to form hydrochloric acid (HCl) and hypochlorous acid (HOCl).

What are 3 interesting facts about chlorine?
Fun Chlorine Facts
- Chlorine rarely occurs freely in nature.
- Chlorine is the third most abundant element in the Earth’s oceans.
- Chlorine is the 21st most abundant element in the Earth’s crust.
- Chlorine is the ninth most abundant element in the human body.
- Chlorine gas is has a yellow-green color and a strong smell.
What are three chemical properties of chlorine?
Are the properties of chlorine and sodium chloride the same properties?
The compound composed of these ions exhibits properties entirely different from the properties of the elements sodium and chlorine. Chlorine is poisonous, but sodium chloride is essential to life; sodium atoms react vigorously with water, but sodium chloride simply dissolves in water.
How does chlorine behave?
Chlorine is a very active element. For example, chlorine reacts explosively with hydrogen to form hydrogen chloride: Chlorine does not burn but, like oxygen, it helps other substances bum. Chlorine is a strong oxidizing agent (a chemical substance that gives up or takes on electrons from another substance).
What are 5 facts about chlorine?
What are the physical characteristics of chlorine?
The Physical properties of Chlorine are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
What are three characteristic properties of chlorine?
Chemical Properties General. Chlorine has a characteristic penetrating and irritating odor. Atomic and Molecular Properties. Atomic Weight – 35.453 Molecular Weight of Cl 2 – 70.906 Chemical Properties. The mass of a unit volume of chlorine at specified conditions of temperature and pressure. Flammability. Valence. Chemical Reactions.
What are some interesting facts about chlorine?
– Only fluorine is a lighter halogen than chlorine. It is the second most common halogen on Earth. Chlorine has been in use for thousands of years in other forms, but it wasn’t named until 1810 by Sir Humphry Davy.[1] – Around 1.9% of the ocean’s mass is composed of chlorine atoms. Chlorine gas was used by the Germans in WWI to poison the Allied soldiers. It has a high density for a gas of 3.21 grams per liter (air is around 1.29 grams per liter). Chlorine is used to make chlorofluorocarbons or CFCs.[2] – Chlorine is classified as an element in the ‘Halogens’ section which can be located in group 7 of the Periodic Table. The term “halogen” means “salt-former” and compounds containing halogens are called “salts”.[3]
What are the chemical properties of chlorine?
The chemical properties of chlorine resemble those of the other halogen elements. It has seven electrons in its outermost shell and is very electronegative; it therefore has a strong tendency to attract electrons from other atoms, making it a powerful oxidizing agent.
