solecistsays...ahh, so that's how they make blue curacao.
NicoleBeesays...nitric dioxide? What happens to the copper?
mintbbbsays...I have forgotten most of my chemistry by now, so I have to just dig the equation out:
Cu(s) + 4HNO3(aq) ——> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
Cu(NO3)2 is water soluable, that's why the liquid turns light blue (because of the copper ions).
Though I am seeing different equations on the web when I browse. Anyway, copper turns into a water soluable salt that then turns the water blue.
Sorry about a choppuy explanation. Like I said, I haven't touched chemistry in years, plus my English science vocabulary isn't up to par
NicoleBeesays...Thank you so much! I used to love chemistry so much. (Not that I was any good at it, but..) Really should have gone into it.

ponceleonsays...Is the glass on those hoods bulletproof? Just curious...

deathcowsays...dude, i'll give you $10 to take a monster hit off that flask

The ones I have ever used were made of plexiglass, or at least some form of plastic. I do not remmeber seeing one made with glass, but then I have never used one outside a college chemistry lab or a high school.
