Question

What are some chemical properties of chlorine?

Answer 1

Chlorine gas is diatomic, with the formula Cl2. It combines readily with all elements except O2 and N2[2] and the noble gases. Compounds with oxygen, nitrogen, and xenon are known but do not form by direct reaction of the elements.[3] Chlorine is not as extremely reactive as fluorine. Pure chlorine gas does, however, support combustion of organic compounds such as hydrocarbons, although the carbon component tends to burn incompletely, with much of it remaining as soot.[4] At 10 °C and atmospheric pressure, one liter of water dissolves 3.10 L of gaseous chlorine, and at 30°C, 1 L of water dissolves only 1.77 liters of chlorine.[2]

This element is a member of the salt-forming halogen series and is extracted from chlorides through oxidation often by electrolysis. As the chloride ion, Cl−, it is also the most abundant dissolved ion in ocean water.
