Why is sulfur associated with volcanism?
The article did not answer my question: Why is sulfur associated with volcanism? It is a literally universal phenomenon, most notably on Jupiter's moon Io, so clearly there is something critical being left unmentioned in this article. I suspect it is a combination of the element's abundance, density, and melting points, but I'm not sure how that interplay works out. Badon (talk) 09:15, 26 May 2014 (UTC)
- The synonym brimstone, despite wrong information given in this article, derives from sulphur's abundance at the conal rim of volcanoes.
Direct reactions between elemental sulfur and other elements
I have removed the following claim (formerly the last sentence of the opening paragraph):
- Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases.
The "except" portion directly contradicts the assertion in Wikipedia's own article on Iridium(III) sulfide, which specifically states that this compound can be "prepared by heating a mixture of elemental iridium and sulfur." An unfortunate complication: when I tried to find further documentation for this assertion, the reference I found described synthesis of a different compound, iridium disulfide
[iridium(IV) sulfide], by direct reaction between the elements at atmospheric pressure. I have therefore created the new article Iridium(IV) sulfide Iridium disulfide, using that reference. The basic point still remains: iridium and sulfur do react directly, contrary to the "except" clause of the claim I have removed.
I would have preferred to correct, rather than simply remove, the false claim. Unfortunately, to make this possible, a correct statement about the exact extent of sulfur's reactivity with other elements will need to be found in a source; synthesizing this information ourselves, from multiple sources, would be WP:OR (specifically, WP:SYNTH).
- Well said. I probably was the one who committed the crime of overstatement.--Smokefoot (talk) 14:04, 19 January 2019 (UTC)
- This dependence upon the establishing of authoritative sources, and not simply upon assertions based in scientific proof, will ultimately prove the doom of Wikipedia.
