Detection of GnHCl

[Wolfgang Schechinger]

Richard, 

You still remember the 1st year anorganic course?: If GuHCl is the 
only one  source of chloride (halogen) ions in your solution, you 
might check for this ion using silver nitrate solution. You'll get a 
characteristic white precipitate that does not dissolve in diluted 
nitric acid. Of course you also could measure chloride with a routine 
analyzer in clinical chemistry, if you have access to any.

Wolfgang

PS

Richard, please excuse my ignorance, but my latin's buried. What 
means "In Ventum Faciens Aquam" - "making water in the wind" gives no 
sense to me.
