| 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 :) | 08:48 |
| azonenberg | copper nitrate? | 08:52 |
| 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 | 08:53 |
| soul-d | http://www.youtube.com/watch?v=2yE7v4wkuZU | 08:54 |
| soul-d | is one i followed with hcl copper and kno3 | 08:54 |
| soul-d | and used the more complicated one with going trough the h202 but only had 3% | 08:56 |
| soul-d | so basicaly i set it up and ran :P | 08:57 |
| 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 | 09:03 |
| berndj | glass is an acid in a sense. it's pretty okay standing up to other acids | 10:06 |
| berndj | you're not going to oxidize silicon dioxide any further :) | 10:07 |
| soul-d | did learn naoh in pet bottle is ah no :P | 10:33 |
| berndj | glass doesn't do super well against NaOH either | 10:40 |
| 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 | 10:42 |
| soul-d | need spectromiter i think my hunt for yellow iron oxide gave me some blue grains | 11:30 |
| Sync | hmm | 14:10 |
| Action: Sync buys moar tooling | 14:11 | |
