Fluoridation vs. Fluorination

I disagree that the distinction between Fluorination (which links here) and Fluoridation is "unnecessary," as the revert by Edgar181 asserts. It's a very easy mistake to make and is in line with a lot of other Wikipedia pages that abate this type of confusion in the same way. Maybe my Wiki markup isn't correct, though; I welcome a correction on this. In any case I've heard Fluoridation referred to as "Fluorination" in the past and indeed I'd arrived at this page by accident. Please don't revert the edit again unless there is a specific Wikipedia policy reason, that can be cited, not to include it. —Preceding unsigned comment added by 96.242.156.9 (talk) 03:34, 5 October 2008 (UTC)

OK, I understand now. I didn't realize that fluorination redirected to halogenation. I agree that there should be some kind of note at the top, but I have reworded it a bit to make it more clear and to match the standard wording used on other Wikipedia articles. Does this work for you? -- Ed (Edgar181) 10:50, 5 October 2008 (UTC)

Makes sense, thanks.--96.242.156.9 (talk) 18:24, 6 October 2008 (UTC)

Chemical reaction written incorrectly

The chemical reaction of trichloroethylene with hydrogen fluoride should not have hydrogen fluoride above the arrow but instead as a reactant as it is not a minor reactant, a catalyst, or added heat. Also, because it is the only source of fluorine in the formation of the intermediate trifluorochroloethane, it is a major reactant in that step and as such should be listed on the reactant side of the equation. This holds true also for Bromine in the next step of the equation, it is not a catalyst but instead a major reactant for that step. — Preceding unsigned comment added by 65.67.110.40 (talk) 16:07, 17 June 2011 (UTC)

In the depiction of organic reactions, it is standard practice to place some reactants (whether "minor" or "major") over the arrow, so I don't think there is anything incorrect about the diagram. -- Ed (Edgar181) 17:15, 17 June 2011 (UTC)

Oxychlorination?

This needs work. In the context of water purification (which is a very different context from the present section), I thought oxychlorination meant use of chlorine dioxide. Oaklandguy (talk) 21:26, 5 March 2014 (UTC)

Intro

The intro is misleading. Organic compounds undergo halogenation much more readily than inorganic compounds. Try hydrogen, chlorine and some quantums of UV light. --ZdBdLaLaLa (talk) 17:32, 7 April 2016 (UTC)

Density

There is mention in Separatory funnel that "The more dense liquid, typically the aqueous phase unless the organic phase is halogenated, sinks and can be drained out through a valve away from the less dense liquid, which remains in the separatory funnel". It might be worth adding a paragraph about when and how halogenation affects density, and mentioning separation as an example of the effect's use. 92.25.47.124 (talk) 14:43, 25 February 2020 (UTC)
