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

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.

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!

My friend Ivan @ Periodictable.ru made this before:


I'll ask him to post it on Wikipedia

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? [Edited on 27-8-2012 by Endimion17]

It's O4

@Endimion- I work with him closely, I share some of my projects with him and vice versa, and I relay orders on his behalf.

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.

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.

My tube furnace releasing the last molecules of SO3 from NaHSO4 at 820 Celsius

The final result


keep photos online

Wow, SO3 is an amazing substance, I always wanted to make some and do some nitronium sulphate-based nitrations I don't have the equipment to do so, though.

It seems there isn't an appropriate thread for showing all kinds of weird stuff found online, but this is the closest one here because there are photos inside this link.

Adrian's Home Chemistry Lab

If this is one of you, guys, I'm sorry for my ignorance. It's just that I'm amazed by the awesomeness of this lab. Not only it looks like a 19th century lab where some guy discovered a chemical element, but it even has a freakin' organ inside to add some general spookiness.
The videos are really cool, do check it out.
One thing scares me a bit - I don't see a ventilation system and it seems like the lab is a neat place to slowly poison yourself as the years go by.

Also, I wouldn't keep a neat and expensive thing like an organ inside a lab where corrosive fumes linger around...

Two small bromine apoulles and a small flask with the rest of the bromine what I have used in a reaction.

Each ampoulle contains 25-30g of pure Br2, wouldn't be funny to break one

Oh this will be my topic. I love photography and i came to love with chemistry.

It turns out that making NO2 is easy. I used a TV circuit high voltage line, a couple of canadian 25 cents (pure nickel). I also added a small cup of water to absorb the NO2 and make HNO3.

I'm new to the forums and figured I'd just introduce myself with a picture.

Italian might be familiar with this stuff based on his previous posts.

Iron Acac crystals. Also, I have Copper Acac but it's kinda boring to look at.

More nice pictures!

A certain charm

These aren't necessarily "pretty" but I wanted to post them anyways. I always thought chemical containers from back in the day have a certain charm to them...






Compared to today's modern bottles...

Some recently made white P, cleaned with chromic acid.

Happy Halloween.

This is a photo of about two grams of manganese(III) acetylacetonate prepared by manganese(II) sulfate and acetylacetone. The oxidation to Mn(III) was carried out using potassium permanganate

Left side: my starting material, a highly substitued pyrrole (also prepared by me), right side: the compound what I have made from it. Both are under UV.

Here are chlorine bubbles through olive oil. This was my attempt to isolate chlorine gas by electrolysis. I was hoping that olive oil would be inert enough not to react too much with chlorine, but it ended up reacting anyway. If you look closely at the top of the column, you'll see white streaks where the oil reacted with the chlorine. At the beginning, the oil was perfectly clear.

[edit] the additional picture is not pretty, but I included it to show the extent of the chlorination.

That is really cool yeti! I might try that just for fun!

Time for Tin! (again)

I made more tin crystals from an acidic solution of tin chloride- normally you add granular zinc to the solution to start the reaction and create the "floating tin sponge"

This time I wanted to try with a zinc rod which was too heavy for the bubbles to lift, It made a beautiful tin tree type thing.

The solution is ~0.5 M in SnCl2 and 2 M in HCl

I wish I had something better than an iPhone5 to take pictures, every time I try to show you guys something it turns out shittier than my eyes see it! Thanks though

It's not bad Mailin'. [Brace yourself for constructive criticism] one parameter you could improve is the lighting.
The more light available for the picture, the better it tends to turn out. Just make sure you don't go overboard either.

Not bad- could be better I actually did the reaction on a windowsill thinking that the bright daylight would show off the crystals more, but it didn't, so I had to use flash which made it.... Okay.

iPhone are not the masters of photography I have to admit, next time I will try a light behind me or something. I plan to grow some electrolytic tin crystals, but I will figure out my lighting before I do it, for sciencemadnesses' sake

Thanks for the criticism though, I love taking pictures of what I do, I just need to perfect doing it with what I have!

Carborundum (silicon carbide), and it's fairly old container. Very hard and extremely shiny little bits- glass can easily be scratched with a granule of this stuff...

Fine Silver 5 Troy Ounce Bars

Bathing in dilute sulfuric acid to remove all traces of flux from the melt.

Each of these bars weigh between 5.020 and 5.040 troy ounces.

Stamped Bar

After having the fine silver crystals (grown in my electrolytic silver cells) assayed by NTR Metals, I hand stamp the bars.

These sell on Ebay for 5 to 10 percent over spot price.

After Ebay fees, I net right at spot for each of these bars.

Platinum Leach from Catalytic Converters

Here is a shot of some platinum and palladium in solution from leaching automotive catalytic converters in hydrochloric acid and clorox.

The solution is course filtered via gravity first using several coffee filters to remove large particulate from the solution.

Then it is filtered a second time using vacuum assist through a whatman number 5 fine filter paper.

Platinum Group Metals Mixed Black Powder

This is the platinum group metals that have been cemented (precipitated) using pure zinc metal shavings.

The zinc shavings were added to the platinum/palladium solution and the metals "cement" into the zinc trading places as the zinc goes into solution, and the platinum groups metals precipitate out of the solution.

See "electromotive series" or "replacement series" for an explaination of how this works.

These mixed (platinum, palladium, and probably rhodium) black powders are pure metal. But they will need to be refined (seperated) from each other using some complex chemistry (of which I know very little).

Pure Gold Bar 1.7 Troy Ounce 99.5% Pure

Here is a pure gold bar that I produced using chemistry and metalurgy to remove impurities from the gold (10k and 14k scrap jewelry).

The scrap gold was alloyed with scrap 925 silver then treated with dilute nitric acid to dissolve most of the base metals - nitric acid will not dissolve gold, but it will dissolve out the base metals.

The resulting gold was then dissolved using a mixture (4 to 1) of 31.45% hydrochloric acid (from Lowes) and concentrated (68%) technical grade nitric acid.

After removing any excess nitric acid and filtering, the pure gold powder was precipitated out of solution using a saturated, and filtered solution of sodium metabisulfite.

There is a tiny bit of contamination seen as tiny bumps and irregularities on the surface of the bar to the left.

To get this bar up to spec, I would have redissolved the gold powder in hydrochloric acid and clorox (from the Dollar Store), then precipitated again using boiling oxalic acid (99.9% ACS) to produce a bar in the range of 99.99% purity.

This bar was sold to a big refinery, so I did not waste the time and chemicals to refine it all the way to industry standards of 99.95% purity.

Thanks for looking.

[Edited on 14-11-2012 by Pyro]

lol, yes with nitric acid is abouth the ony way best is nitric acid and sugar, nitric acid and any cheap metal works well too, but less effective. read my post about it to get all details.

Just some new photos:

In old times when they used nitrocellulose in the cinemas there was a lot “accident’, because the film easily ignited, like on this picture:


And a few crystal at the bottom of my breaker under UV, it is a pyrrole polycarboxylic acid amide, looks like a spiders nest(:


Isn't chemistry just simply beautiful?

Oh...suuuuuuure......... It was supposed to be proprietary and top secret, but what the hell

It's a rather crude set up I made in about 15 minutes. Anything similar to this set up will work, whether its a test tube, glass plate with foil on either side etc. I used a test tube because it allowed me to coil wire on the outside and fill the inside with foil which has lots of sharp corner and edges which seems to be where the plasma concentrates itself.

The more blue glow you see, the more ozone you are making.


First a metal wire with a hook with roughly the same curve as the test tube bottom was stuck into the tube. Then aluminum foil was jammed in in small pieces and compacted quite a bit with a metal rod. This forms one electrode.


Then wire was tightly wound around the tube as shown here. It helps to wind it around the tube, remove the "spring" of wire and tighten it to make it have a smaller diameter and then push it onto the tube to ensure it stays on tightly without needing tape etc.


At first I tried to use this small transformer chip that came from a small neon tube display... It produced no glow or ozone. Im not sure what voltage these things operate at but obviously not high enough. The output wires do arc though and give nasty little shocks.


So instead I took out the bigger guns and used a real induction coil (which does give a wicked shock...), this thing easily makes 3 inch long sparks through the air. I'm not entirely sure of the output voltage but the only power supply I have is 6V, 3A. Just connect the output terminals of your HV source to either of the electrodes on the tube (doesn't matter which one) and you have a crude ozone generator.


This is just running the coil with alligator clips on a porcelain dish...


PS: If somebody could enlighten me on how to calculate the output voltage of this induction coil it would be appreciated. Im not a big electronics guy and this was just something I bought on eBay due to good pricing.

I plan to place this tube into a larger glass vessel and use an air pump to circulate air through it and have a dilute source of ozone. This test alone gave me a horrid sore throat the next morning... which I am directly blaming having my face too close to the damned thing for so long. Nonetheless.

You can do this too... http://www.bigclive.com/oz.htm
