You can use brine to break an emulsion, but it's better not to have emulsions in the first place. "Caveman Chemistry" previously had a nice description and slide show of producing Chlorine, Hydrogen, and Lye from table salt, using PET bottles, flashlight batteries, glue and stuff. It's not there anymore but I posted the full method previously, here: http://www.mail-archive.com/biofuel@sustainablelists.org/msg28376.html Re: [biofuel] Re: Hydrogen Economy Best wishes Keith >On Oct 30, 2005, at 2:19 PM, Thomas Kelly wrote: > >> >>I'm having difficulty getting Phosphoric Acid.
