Angelika Posted February 13, 2007 Posted February 13, 2007 Hi, can you show me how to prepare dry hydrogen using the usual apparatus.
YT2095 Posted February 13, 2007 Posted February 13, 2007 personally I`d add NaOH to Alu foil and bubble the gas through Conc Sulphuric acid.
John Cuthber Posted February 13, 2007 Posted February 13, 2007 I'm paranoid enough that I'd include an anti suck back trap. Not least because I suspect this is a homework question. I have neutralised 50% NaOH solution with conc sulphuric but I wouldn't want to do it by accident (and I don't really reccomend it).
