Chlorine and oxygen can bond in a number of ways: chlorine monoxide radical, ClO•, chlorine (II) oxide radical; chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical; chlorine dioxide, ClO 2, chlorine (IV) oxide; chlorine trioxide radical, ClO 3 •, chlorine (VI) oxide radical; chlorine tetroxide radical, ClO 4 •, chlorine (VII ...
Evaporation under reduced pressure allows it to be concentrated further to about 40%, but then it decomposes to perchloric acid, chlorine, oxygen, water, and chlorine dioxide. Its most important salt is sodium chlorate, mostly used to make chlorine dioxide to bleach paper pulp. The decomposition of chlorate to chloride and oxygen is a common ...
Chlorine monoxide is a chemical radical with the chemical formula ClO •. It plays an important role in the process of ozone depletion. In the stratosphere, chlorine atoms react with ozone molecules to form chlorine monoxide and oxygen. Cl • + O 3 → ClO • + O 2. This reaction causes the depletion of the ozone layer. [1]
Chlorine dioxide is approximately 10 times more soluble in water than elemental chlorine [1] but its solubility is very temperature-dependent. At partial pressures above 10 kPa (1.5 psi) [1] (or gas-phase concentrations greater than 10% volume in air at STP) of ClO 2 may explosively decompose into chlorine and oxygen. The decomposition can be ...
Because this reaction is highly exothermic (238 kJ/mol), the temperature is monitored, to guard against thermal degradation of the catalyst. The reaction is as follows: CH 2 =CH 2 + 2 CuCl 2 → 2 CuCl + ClH 2 C-CH 2 Cl. The copper(II) chloride is regenerated by sequential reactions of the cuprous chloride with oxygen and then hydrogen chloride:
The earliest method of synthesis was to treat mercury(II) oxide with chlorine gas. [3] However, this method is expensive, as well as highly dangerous due to the risk of mercury poisoning. 2 Cl 2 + HgO → HgCl 2 + Cl 2 O. A safer and more convenient method of production is the reaction of chlorine gas with hydrated sodium carbonate at 20–30 ...
Chlorine trifluoride dioxide is an inorganic compound of chlorine, ... Alternatively it can be made by a reaction of chlorine trifluoride with oxygen gas: [2]
This is the mechanism of bleaches based on chlorine but also of oxygen-anions which react through the initial nucleophilic attack. [12] A reducing bleach works by converting double bonds in the chromophore into single bonds. This eliminates the ability of the chromophore to absorb visible light. This is the mechanism of bleaches based on sulfur ...
