# Talk:Iodine

@117.242.96.196 changed the melting and boiling point in the intro. This was reverted by @Favonian, readded, reverted by @Cannolis, then readded in a reviewed by @HypeBoy which I reverted. 
The number being added is a conversion formula applied to a three digit number then quoted to 4 significant figures. This is incorrect.  Moreover it is completely unnecessary in the intro. The goal of this temperature in the intro is to give an since of this unusual property of Iodine. This is not a reference number. It should be approximate, corresponding to normal readers experiences. Johnjbarton (talk) 02:21, 19 October 2024 (UTC)

I agree with Johnjbarton. The unwarranted increase in precision was my reason for reverting, though I must apologize for not providing an edit summary to that effect. Favonian (talk) 07:59, 19 October 2024 (UTC)

I'm not so sure that titanium and zirconium are purified by this process. Perhaps remove? 
Titanium is purified by distillation of TiCl4, obviating the need for this very expensive process Fsikkema (talk) 10:02, 25 October 2024 (UTC)

Well, in comparison to the rambling discourse on the chemistry of all things iodide (vs all things iodine), we can afford to keep the Van Arkel- de Boer process.  It is still mentioned in Ullmann's Encyclopedia for the prep of ultrapure Ti, Zr, Hf, and Si.--Smokefoot (talk) 11:19, 25 October 2024 (UTC)

Can we get rid of this pending revisions thing? It is poorly documented and I don't know how to reject/accept/comment on these. Just plain protection is better IMO. Johnjbarton (talk) 18:09, 27 October 2024 (UTC)

Just noting that the {{use British English}} tag at the top and the spelling sulfur in the article conflict with each other. (Choosing my words carefully, to avoid specifying either as the correct one.)
I haven't checked whether the article as a whole is using British or American English—I just happened to come across a discussion about this particular spelling. Musiconeologist (talk) 14:14, 22 January 2025 (UTC)

@Musiconeologist: Wikipedia follows IUPAC's recommendations. Please see WP:SULF for the details. Favonian (talk) 14:49, 22 January 2025 (UTC)
@Favonian Ah, right. It's interesting that they recommend a mixture of US (sulfur) and UK (aluminium, caesium) spellings/names. Thanks! Musiconeologist (talk) 16:16, 22 January 2025 (UTC)
