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 is the chemical structure of chlorine?

Formula and structure: the chemical structure of chlorine gas is Cl2 and its molecular weight is 70 g/mol. Its structure is Cl-Cl, which is also called the element form of the chlorine element, consist in 2 atoms of chlorine joined by a covalent bond.

What are the physical properties of bromine?

Physical and chemical properties Free bromine is a reddish brown liquid with an appreciable vapour pressure at room temperature. Bromine vapour is amber in colour. Bromine has a pungent odour and is irritating to the skin, eyes, and respiratory system.

What are the physical properties and uses of helium?

Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium was the first gas used for filling balloons and dirigibles.

What are physical and chemical properties of sodium?

It’s a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.

What is the physical and chemical properties of salt?

Salt is a chemical compound with a number of interesting properties: Crystals or white crystalline powder. Transparent and colourless in crystalline form – rather like ice. Crystallises in the isometric system, usually in the form of cubes.

What are three characteristic properties of chlorine?

Some of the chemical/physical properties of chlorine include: Chlorine is a yellow-green gas at room temperature. Chlorine has a pungent, irritating odor similar to bleach that is detectable at low concentrations. The density of chlorine gas is approximately 2.5 times greater than air, which will cause it to initially remain near the ground in areas with little air movement.

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 the physical properties of chlorine?

Physical Properties. Chlorine is a yellow-green gas with a density greater than air (3.214 g/L), a melting point of −101.0 ° C, and a boiling point of −34.4 ° C. It has a strong pungent odor.

What is the purest form of chlorine?

Sodium chloride is the most common compound of chlorine, and it is abundant on Earth, especially in seawater. Chlorine in its pure form is yellowish-green, but its common compounds are typically colorless. Chlorine in its pure form is yellowish-green, but its common compounds are typically colorless. Chlorine is capable of joining with practically every element, producing a chloride.
