Color
editThere 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
editWe 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)
Health effects
editSince 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)
- 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)
