Pretty strong stuff stomach acid is!

Perhaps it could be extracted from puke?

I am back again... I did not yet try to actually make HCl. But in the meantime I pursued the idea of making phosphoric acid from fertilizer and wrote
about the result in another thread whih is already covering this issue:
http://www.sciencemadness.org/talk/viewthread.php?tid=7370#p...
(I got at least *some kind of* phosphoric acid, but I am afraid it is not H3PO4.)
Here is another alternative I found in a book:
H2S + Cl2 = 2 HCl + S
If I understood correctly, this reaction is "silent", not like H2 + Cl2. H2S could be made by heating paraffin together with sulphur - so no acid
would be needed during the process -, and the sulphur would be regenerated by the reaction. Only that I do not like the idea of making so many ugly
gasses at a time, so I am not sure if I ever want to try this out.

H2S is not only ugly it is deadly. One member here had a narrow escape from it.
