  2. Adsorbable organic halides - Wikipedia

    en.wikipedia.org/wiki/Adsorbable_organic_halides

    Adsorbable organic halides (AOX) is a measure of the organic halogen load at a sampling site such as soil from a land fill, water, or sewage waste. [1] The procedure measures chlorine, bromine, and iodine as equivalent halogens, but does not measure fluorine levels in the sample.

  3. Chlorine-releasing compounds - Wikipedia

    en.wikipedia.org/wiki/Chlorine-releasing_compounds

    Chlorine-releasing compounds, also known as chlorine base compounds, is jargon to describe certain chlorine-containing substances that are used as disinfectants and bleaches. They include the following chemicals: sodium hypochlorite (active agent in bleach ), chloramine , halazone , and sodium dichloroisocyanurate . [ 2 ]

    2, portlandite) produced by Portland cement hydration in concrete to form calcium carbonate (CaCO 3) while releasing a water molecule in the following reaction: CO 2 + Ca(OH) 2 → CaCO 3 + H 2 O. Exception made of the water molecule, the carbonation reaction is essentially the reverse of the process of calcination of limestone taking place in ...

  5. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    The relative rates at which different halogens react vary considerably: [citation needed] fluorine (108) > chlorine (1) > bromine (7 × 10 −11) > iodine (2 × 10 −22).. Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction.

  6. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Following the usual trend, bromine is less reactive and iodine least of all. Of the many reactions possible, illustrative is the formation of gold(III) chloride by the chlorination of gold. The chlorination of metals is usually not very important industrially since the chlorides are more easily made from the oxides and hydrogen chloride.

  7. Halogen addition reaction - Wikipedia

    It forms for an instant a single sigma bond to both of the carbon atoms involved. The bonding of bromine is special in this intermediate, due to its relatively large size compared to carbon, the bromide ion is capable of interacting with both carbons which once shared the π-bond, making a three-membered ring. The bromide ion acquires a ...

    Inorganic forms of chlorine-releasing compounds frequently used in residential and public swimming pools include sodium hypochlorite commonly known as liquid bleach or simply bleach, calcium hypochlorite and lithium hypochlorite. Chlorine residuals from Cl 2 and inorganic chlorine-releasing compounds break down rapidly in sunlight.
