Fluorine is handled in equipment built out of certain alloys of copper and nickel. The halogens can be made by reacting a solution of the halide ion with any substance that is a stronger oxidizing agent.
Many of the halides may be considered to be salts of the respective hydrogen halides, which are colourless gases at room temperature and atmospheric pressure and except for hydrogen.
Fluorine F 2 , a highly toxic, colorless gas, is the most reactive element known so reactive that asbestos, water, and silicon burst into flame in its presence. Contributors Jim Clark Chemguide.
Iodine, for example, can be made by reacting the iodide ion with either bromine or chlorine. Fluorine is so reactive that it is difficult to find a container in which it can be stored.
This is a reversible reaction, but the complex is very stable, and the position of equilibrium lies well to the right. In theory, the same process can be used to generate strong oxidizing agents, such as F 2.halides and concentrated sulphuric acid
Chlorine reacts with the OH - ion to form chloride ions and hypochlorite OCl - ions. None of the halogens can be found in nature in their elemental form. Part of the problem was finding an oxidizing agent strong enough to oxidize the F - ion to F 2.
As a result, it has an oxidation number of -1 in all its compounds. These compounds are all colorless gases, which are soluble in water.
By 'easily', assume I mean in the thermodynamic energetic sense. Fluorine is the most electronegative element in the periodic table.
Iodine is the only halogen that forms an XY 7 interhalogen compound, and it does so only with fluorine. Silver iodide AgI plays an important role in the photographic process and in attempts to make rain by seeding clouds.
The equation for this reaction is given below: Chlorine Cl 2 is a highly toxic gas with a pale yellow-green color. The absence of a precipitate with fluoride ions is unhelpful unless it is known that a halogen is present; otherwise, it indicates that there is no chloride, bromide, or iodide.
