08:48 <soul-d> any chemical wizards in here Q:how to clean up glassware containing "uknown" substance pretty much strong acids one i remmer is left over from reaction of hcl 30% copper and kno3 ( to make hno3 i think it was )

08:48 <soul-d> fun stuff like that without having a clue :)

08:52 <azonenberg> copper nitrate?

08:53 <soul-d> yeah thats probably left over

08:53 <azonenberg> copper chloride?

08:53 <azonenberg> I'd assume water soluble in either case

08:53 <azonenberg> maybe sonicate

08:53 <azonenberg> and heat a little

08:53 <soul-d> chloreide the reaction was sopposed to be regenarateble by adding alumium and more copper

08:54 <soul-d> http://www.youtube.com/watch?v=2yE7v4wkuZU

08:54 <soul-d> is one i followed with hcl copper and kno3

08:56 <soul-d> and used the more complicated one with going trough the h202 but only had 3%

08:57 <soul-d> so basicaly i set it up and ran :P

09:03 <soul-d> but main concern is how much glas is atacked over time by chemicals :P

09:03 <soul-d> since it's been sitting to long

10:06 <berndj> glass is an acid in a sense. it's pretty okay standing up to other acids

10:07 <berndj> you're not going to oxidize silicon dioxide any further :)

10:33 <soul-d> did learn naoh in pet bottle is ah no :P

10:40 <berndj> glass doesn't do super well against NaOH either

10:42 <soul-d> yeah the reason but it did leak destroy part of the table ( rarly visit shed over in winter ) now it's good time to get stuff cleaned up

11:30 <soul-d> need spectromiter i think my hunt for yellow iron oxide gave me some blue grains

14:10 <Sync> hmm
