A highly reactive oxide of chlorine with chemical formula OClO. This species is of importance in the chemistry of polar stratospheric ozone depletion, as it is a product of the reaction of ClO with Br [..]

Powerful oxidizing agent used to delignify and remove colored substances from pulp. The oxygen in chlorine dioxide initially reacts with lignin. This initial reaction produces substances that can chlo [..]

This reddish-yellow gas crystallizes as orange crystals at −59 °C. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleaching.

is a powerful oxidant used in disinfection but it is more difficult to handle than other forms of chlorine. It must be generated on-site and requires trained staff to manage it.

A chlorine-based chemical sanitizer. In contrast to sodium or calcium hypochlorite, the activity of chlorine dioxide is less affected by changes in pH or the presence of organic matter.

ClO2, a radical, undergoes photodecomposition in the stratosphere where the products of this reaction react with ozone. Since this is a photochemical reaction it only takes place while the sun is up. [..]
