CHEMICAL SYMBOL FOR CHLORINE FREE

Hypochlorous acid HClO Hypochlorous acid But a number of compounds with this element can be obtained indirectly: The reaction of chlorine with oxygen - oxygen compounds of chlorineĬhlorine does not directly react with oxygen. With other halogens, chlorine forms interhalogen compounds: for example, strong oxidizers - the fluorides ClF, ClF₃ and ClF₅. Chlorine does not react directly with carbon and inert gases, oxygen and nitrogen. On heating, chlorine interacts with phosphorous, arsenic, boron and other non-metals. At room temperature, chlorine interacts with sulfur and fluorine. Hydrogen chloride forms as a result:Ī solution of hydrogen chloride in water is called hydrochloric acid. With hydrogen, chlorine interacts either on ignition, or when a mixture of chlorine and hydrogen is exposed to ultraviolet light. On heating, chlorine reacts with aluminum: The equation of the reaction is:ĢSb + 3Cl₂ = 2SbCl₃ Antimony trichloride For example, without heating chlorine enters into a reaction with alkaline and alkaline earth metals, and with antinomy.

Chlorine is poorly soluble in water and highly soluble in many non-polar liquids.Ĭhlorine enters into an interaction with the majority of metals and many non-metals.

CHEMICAL SYMBOL FOR CHLORINE FREE

In a free state, chlorine is present in the form of diatomic molecules Cl₂.

The melting temperature of chlorine in a solid state is -100.98 degrees Celsius, and its boiling point is -33.97 degrees Celsius. In ordinary conditions, chlorine is a yellow-green gas, with a density exceeding the density of air by 2.5 times. The chemical and physical properties of chlorine Here you’ll find an easy experiment on obtaining chlorine at home. Only the English scientist Humphrey Davy, who tried many times to break down “muria oxide” into simple substances, established in 1811 that the poisonous green gas was a simple substance that corresponded to a chemical element. Another scientist, Lavoisier, also believed that chlorine was an oxide of “muria” (hydrochloric acid). Initially Scheele took the new gas to be an oxide of hydrochloric acid and called it “dephlogisticated hydrochloric acid”.

The scientist heated hydrochloric acid with mineral pyrolusite, and observed the release of a yellow-green gas with an unpleasant smell. Chlorine was first obtained and described in 1774 by the Swedish chemist Karl Scheele.
