Aydrian's Fotothing

lab, chemistry? I know what you mean. I do the same on my uni :))

Really? I didn't know you studied chemistry, too! :D You're getting nicer and nicer to my eyes =P

ciao Aydrian ! grazie per i commenti :)

a disposito *inchino* ;)

Omg just read this comment, thanks *blushes*

I actually study molecular biology, but THAT's LOADS of chemistry too ;)

yeah, I suppose... that's not properly easy =P
Wow, great! A colleague! :D Yay!

*zomp zomp*

*zomp zomps back at ya* lol

P.S: so collegue, what is this red thingy....? Does it have something with Cu2+ ?

Nope, something MUCH MUCH cooler :D Actually, the photo is of poor quality. The colour is kinda intense, purple. It looks a little bit like KMnO4, but in this case this is the next part of the experiment: first you dissolve some gold, than you treat the solution with Sn2+.

That is what you obtain: a colloidal suspension of... gold :D That's the Purple of Cassius. I still keep some "purple gold" from that experiment =P
