arclight, please post details in another thread. I'm interested in exactly how you produced the Cu mirror band.

If anyone can determine the species, or at least genus, that'd be great.

Might want to try bugguide.net

You can post an ID request or browse their image gallery and try to find a match (could take forever, they have tons and tons of photos).

I am currently crystallizing some caffeine citrate, it has so far made some absolutely beautiful hairlike crystals. Still a bit of solution to dry though, will post pics for sure when its ready.

EDIT:

Here ya go.

It's uncanny how similar to hair they are.

Something interesting:

LIQUID OZONE!

Just made some with an ozonisator, condensed in a test tube with some liquid nitrogen. There was no problem with it until we started the reaction.

The nitrogen/acetone mixture solidified the deuterochloroform what was used as a solvent, the ozone condensed on it and it reacted explosively with the alkene what would have been ozonized. And then: bang.


Never misjudge the power of chemistry. And never forget to use safety glasses!

Wow, liquid ozone? That is amazing, I always wanted to see that! I am sorry for your injuries, though :/

Verg they were very hairy early in the crystallization, but they kinda got bunched while getting them out...

Nice, I had read that it had a deep blue color but I had never seen ozone.

kristofvagyok, hats off!!!
This is amazing, there are no photos of liquid ozone on the entire Web, and I haven't seen it in books, either.

I'm sorry about the mishap, I hope your hand is ok, but well done! This is the real thing. Just... wow!

If that's from an ozonizer, it's not pure ozone, am I right? After all, LN2 should've freezed it.
Or you've managed to remove excess oxygen and nitrogen from the air? Have you fed the machine with pure oxygen?

I'd seriously consider putting this photo on Wikipedia for everyone in the world to see.

Um, I don't think that blue liquid is ozone...
I'll take a guess: A copper-ammine salt. Or cobalt. Or... I give up, what is it?

EDIT: That is liquid ozone, isn' it? I feel stupid, I was kind of expecting a paler blue color from ozone, like liquid diatomic oxygen.

actually, the only other picture (claimed to be) of liquid ozone i have ever seen was a miniscule amount and it was much darker than these samples.

kristof, did you manage to get all of the glass out of your hand? sorry for your pain, sir. i know that sucks, but you did share a wonderful image of a chemical most people will never see in their lifetime. thank you for that!

Well, at first, I want to tell, theat this was not my hand, it was one of my friends who had made this reaction instead of me, because I had another one at this time... But he is okay now.

This explosion was a pity, the glass just "evaporized" to a lot other small pieces (it was 5ml heart shaped flask) and some of it landed in the hand of my friend... It is not serious, it will get better in 1-2-3 days.

The ozone what was produced wasn't pure, it was made from 99,994% oxygen and this contained just a few percent pure ozone.... So the color of the solution is thiswhy so "bright blue".

The accident could be caused by a lot reaction, but the most realistic is that the liquified ozone/oxygen mixture just went off..

A bit offtopic, but does anyone know that how that ozone was produced first time ever in laboratory? It is an interesting reaction, what I have never thought about. I will post it soon(:

Well, the color does seem to be too bright, and it's from an ozonizer, therefore I concluded it's not pure ozone. The standard description is "dark blue liquid", and pure ozone can be solidified using LN2 (I suspect solutions of O3 in O2 have a lower melting point) into a dark blue, purple black solid.

I don't think the quantities made for official experimenting were a lot larger than what it fits into a tiny test tube or perhaps absorption cell for spectroscopy. It's simply too dangerous.

I'm acquainted with periodictable.ru, the guy makes great photos and videos, but I've never seen his photo of liquid ozone before. I'm subscribed to his channel on YT, but it's been a long time since he made any videos...

Liquid Ozone? Wow!! If any of you have played Eve Online you will know liquid ozone powers cyno fields, but I didn't know it existed in real life

I have made liquid oxygen before and its a nice pale blue.

A really useful reaction is based on ozone gas and highly concentrated ozone solutions, this reaction is called ozonolysis(:

And what I have asked and noone replied: the first method for the preparation of ozone in laboratory was made by reaction white phosphorus and dry air (or pure oxygen) in a sealed container. The reaction is spontaneous and ozone concentrations could reach up to 25-30%. I think it's an interesting fact, I would have never thought about this reaction could occur(:

And the picture of the day:

-a nitration's product crystallized at the bottom of the breaker.

@kristofvagyok; What is the reaction mechanism for this method of producing ozone? Does the phosphorus burn or just glow?

Absolutely love the images of liquid ozone, as nearly all of your other photographic work, Kristofvagyok.

I did find one other image of this stuff on the net, and it is much darker indeed:

kristofvagyok, I remember reading about that ozone producing method in one very old book on inorganic chemistry. I don't remember the name of the book, but I think it was printed in Great Britain. What's your source?

Photos - just... wow. :)
