Chlorine is a common element on the Earth, but it is not found naturally in its pure state as it is very reactive and tends to form compounds with other elements. At room temperature and normal pressure, it is a yellow-green gas that is heavier than air. Although some of its compounds...
awhen chlorine is added to water, part of it evaporates into the air, causing the familiar odor, and the rest is present in water in the following forms:chlorine, hypochlorous acid, hydrochloric acid, hypochlorous anion, and chloride. 当氯增加到水时,一部分的它蒸发入空气,导致熟悉的气味,并且...
SymbolClA greenish-yellow, gaseous halogen element that can combine with most other elements and is found chiefly in combination with sodium as common salt. Chlorine is very poisonous, being highly irritating to the nose, throat, and lungs, and causing suffocation. It is used in purifying water...

Chlorine is abundant in cells and biomolecules, yet the biology of chlorine oxidation and reduction is poorly understood. Some bacteria encode the enzyme chlorite dismutase (Cld), which detoxifies chlorite (ClO2−) by converting it to chloride (Cl−) and molecular oxygen (O2). Cld is highly...
