Talk:Hydrogen disulfide

A fact from Hydrogen disulfide appeared on Wikipedia's Main Page in the Did you know column on 5 April 2009 (check views). The text of the entry was as follows:

Did you know... that in high concentrations, the inorganic compound hydrogen disulfide can cause dizziness, disorientation and ultimately unconsciousness?

A record of the entry may be seen at Wikipedia:Recent additions/2009/April.

Color[edit]

There is conflicting information in the given references to the color of the pure oil; one says H₂S₂ is yellow, while another says it is colourless and the yellow color is due to impurities. I suggest that we leave the description of color out of this page until there is some clarity on the issue. PS: I owe a thank you to all who have tidied up my first Wiki page.

I don't know if anyone knows for sure; H2S2 decomposes spontaneously to H2S and S8, the latter of which is of course yellow, so I'm not sure if it's even possible to isolate "pure" H2S2.

Molecular model[edit]

We have all the bond angles and lengths in the article needed for a 3D representation of H₂S₂ - does anyone have access to an appropriate molecular modelling graphics package? Wikiwayman (talk) 14:19, 30 March 2009 (UTC)[reply]

Health effects[edit]

Since hydrogen disulfide quickly decomposes to release H₂S, I think most of its health effects are caused by the latter. But the description is somewhat different from the health effects of H₂S. Similarly, the article describes the odor of H₂S₂ different than is that of H₂S - but I would expect hydrogen (mono)sulfide being also the main source of odor in H₂S₂, since the rotten-egg odor of H₂S is very intense. --79.243.254.103 (talk) 21:08, 2 November 2013 (UTC)[reply]

The decomposition rate of disulfane seems to depend on the solvent it is dissolved in - e.g. there is rapid decomposition in water, but low concentrations of disulfane vapor may be stable in air. So it may be possible to inhale "undecomposed" disulfane, and the health effects caused may be a bit different from that of "pure" hydrogen sulfide. --79.243.227.205 (talk) 23:23, 16 November 2013 (UTC)[reply]
