Talk:realgar

Sulfide or Disulfide
The OED defines "rosalgar" and its more current variant "realgar" both as "disulphide of arsenic"i.e., two sulphur atoms per molecule. The current article's definition as "AsS" rather than AsS2. Dunno if this distinction is worth the difference - can a chemist comment? Originalylem 15:57, 11 September 2010 (UTC)


 * It's actually As4S4 - but AsS is its empirical formula. SemperBlotto 16:14, 11 September 2010 (UTC)
