Aqua regia, hydrochloric acid, etc.

Thank you. There were several discussions on that. Many authors (even in rather reliable sources) confuse Pseudo-Geber with Jābir ibn Hayyān. See, e.g., Talk:Chlorine/Archive1/Archives/1/Archives/1/Archives/1/Archives/1#History and Talk:Hydrochloric_acid#The_discovery_of_Hydrochloric_acid. Historical evidence is rather obscure on this, and obviously Arabic authors massively support Jābir ibn Hayyān (no slight to them though). Materialscientist (talk) 00:10, 3 June 2011 (UTC)Reply
