Chlorine form at room temperature.

Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. Chlorine was first produced by carl wilhelm scheele a swedish chemist when he combined the mineral pyrolusite mno 2 with hydrochloric acid hcl in 1774 although scheele thought the gas produced in his experiment contained oxygen sir humphry davy proved in 1810 that it was actually a distinct. Chlorine is a naturally occurring element found in gaseous form at room temperature. It is an extremely reactive element and a strong oxidising agent.

Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature. It can be converted to a liquid under pressure or cold temperatures. A strong oxidizing agent chlorine deactivates microorganisms by breaking through the cell membrane. Since it combines directly with nearly every element chlorine is never found free in nature.

At room temperature chlorine is a yellow green gas that is heavier than air and has a strong irritating odor. Chlorine has a pungent irritating odor similar to bleach that is detectable at low concentrations. It becomes a liquid at 34 c 29 f. Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase.

The second lightest of the halogens it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Among the elements it has the highest electron. The highly reactive nature of chlorine means it is usually bound with other elements such as sodium chloride salt. It has a choking smell and inhalation causes suffocation constriction of the chest tightness in the throat and after severe exposure edema filling with fluid.

It is two and a half times heavier than air. 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. The temperature at which the liquid gas phase change occurs. Chlorine chlorine physical and chemical properties.

Chlorine is a yellow green gas at room temperature. Chlorine is a yellow green gas at room temperature.
