Why cl2 is a gas

Two of the more common metals are titanium and steel. In the presence of dry chlorine, titanium is flammable. Care should be taken to make sure titanium materials are not used in dry chlorine service. Steel is the most common material used in dry chlorine service. Moist chlorine, primarily because of the hydrochloric and hypochlorous acids formed through hydrolysis, is very corrosive to most common metals.

Platinum, silver, tantalum and titanium are resistant. Consult CI Pamphlet 6 Reactions with Organic Compounds Chlorine reacts with many organic compounds to form chlorinated derivatives. Some reactions can be extremely violent, especially those with hydrocarbons, alcohols and ethers. Additionally, as they degrade, sodium and calcium hypochlorite vent chlorine into the air.

Chlorine gas, on the other hand, is neither flammable nor explosive. Modern cylinder mounted gas feeding systems draw chlorine from the container with a vacuum, so that a failure of any system component results not in the release of chlorine into the air, but in an automatic and immediate shut-off of the chlorine.

By Diane M. Chlorine is supplied as a gas, liquid and a solid. The London dispersion forces become progressively stronger. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases. Why is fluorine a gas, bromine a liquid, and iodine a solid, at room temperature? Chemistry Phases of Matter Changes of State. Ernest Z.
