Filtration of Potassium Nitrosodisulfonate / Fremy's Salt

[balee85]

i did it 3 times yesterday and i got a clear solution. do u know why? is it because it need to be cold or what?

[antiswattt]

wow.. what a waste of chemicals.. potassium permanganate.. :[

Hey! I think I took that course at the UofM at the same time as you :D. I loved this experiment. Something really funny happened to my group's Fremy's salt. For some reason we left the Buchner apparatus while it was filtering and when we came back a couple minutes later we found that the Fremy's salt had combusted!!! I was ecstatic! All that was left was a white plasticy solid.

I am trying to produce the salt but I am not getting success, please send me your procedure

Great video! I'm a woodworker and I'm trying to find a way to oxidize hardwoods, in particular Maple and Walnut. Do you have any ideas as to how I can accomplish this? Thanks!

[silendshade]

nitric acid would oxidize it, since it generally oxidizes everything non-metal except halogens, alto that would be way to expensive (and its not an OTC chemical), why would you want to oxidize hardwood?

(is that hardwood a piece of wood or a whole tree or is it a powder?)

[slaintedan]

For purely aesthetic reasons, some clients like the look of oxidized wood. I've been researching some OTC products available through woodworking suppliers so we'll see if I find something that works well.

Ah. i love chemistry. :)

[ummacles]

Yeah, me too. I mean, I guess I do, now. It was such a chore when actually taking the courses, but now that it's winter break, I've been having dreams entirely about chemistry EVERY SINGLE NIGHT.

[djtrix003]

Yeah, its mostly a love/hate relationship. :D
