So hey, it's been a while but I had a lot of work to do in the lab and
at the university. I used some spare time to work on some Chromium-Complexes
and thought why only show them if I could also add some colored salts to our
photo gallery.

So there are dozens of colored chromium compounds. Too bad that I only have a few of them in my lab. So I will show you the ones I have, those are the most common ones and most people will know them. Still it's nice to see all the different colors of chromium when compared to each other.

I will order some chemicals soon and add more Chromium-compounds to my collection. So there are more colors to come soon ;-).

So let's start:
I will only paste the links because otherwise it's getting too much to load for those who have a slow internet connection !

Chromium(II)
http://imgur.com/oQTrRTZ

This is the nice blue color of Chromium(II). It is not as dark as shown because my camera couldn't do any better. So you can definately distinguish between that blue and the coming later at the Chromium(VI)section. It's much brighter and a bit greener, too. I can't really tell what salt this is, I only know it's chromium(II). I usually reduce all my Chromium(VI) wastes. If you leave that too long you can see how the color shifts from the reduced chromium(III) to a blue color. So I have like half a liter of that solution.

Chromium(III)

- Chromium(III)oxide
http://imgur.com/aBHaMle

- Chromium(III)chloride
http://imgur.com/uxUCfy2

Chromium(III) is usually green especially when it's wet. I bought the Oxide when I didn't have Chromates in order to make them from the Oxide but gave it up due to bad yield. Now I have that bottle here and don't really know what to do with it. The Chloride is just that small sample. I don't have any specific use for that either. It's just there to brighten my collection up a bit. The Chloride is a bit darker, it reminds me of the fake grass you use for toy trains. That grass has that dark color, too.


Chromium(IV)
http://imgur.com/p3sqViM

As you may know there are not that many Chromium(IV)compounds. Most of them are made under high preassure and hot temperatures with dangerous chemicals. So nothnig you could do in a lab. After some research I found that interesting compound in a book. As far as I looked it up on the net I couldn't find anything ( not even the name ). So I don't want to make that too long and describe how I made that. If you are interested you could write me a pm.


Chromium(V)
http://imgur.com/wmcU8O0

So this is a Chromium(V)complex that is not very stable. So I kept that under ice while I made it and just took it out for the picture.

Chromium(VI)

Ammoniumchromate
http://imgur.com/U0UXuO9

Ammoniumdichromate
http://imgur.com/xEYSMhE

Potassiumchromate
http://imgur.com/16zo5Z7

Potassiumdichromate
http://imgur.com/FVoFyRT


Those 4 look really alike ( the Ammoniumdichromate has quite much water in it ) but I still think you can see some difference between Ammoniumchromate and Potassiumchromate. One is bright yellow and the other one has a slight orange tone.

Chromium(VI)Oxide
http://imgur.com/WsYealY

Unfortunately I don't own any CrO3. So I tried to make some by my own. This is Potassiumdichromate in some conc. Sulphuric Acid. It will form some Polychromic Acids and then be condensated to Chromium(VI)oxide. That's the purple stuff you see at the bottom of that flask. While cleaning it I might have had something in my water or in the beaker I used because it reacted back to a yellow liquid ( chromic acid or chromate, I guess ). But it's already on my list.

Chromiumoxide-Peroxide
http://imgur.com/0V2XCeo

Chromoxide-Peroxide-Pyridine
http://imgur.com/QN8sgl3
http://imgur.com/UN3UW6B


So the first one should be known to some, that's what you do to test for chromates. You add some Acid and Hydrogenperoxide to it and it will form Chromiumoxide-Peroxide. It has a dark blue color and is not stable in that solution. So it will decompose to Chromium(III). As Chromium(VI) is a 3d0 Compund you have no Cr-Electrons in your d-Orbitals meaning that you
can perfectly coordinate lone pairs to it. This can either be done in Ether, so the R-O-R' has an Oxygen as bridge. The oxygen has two lone-pairs that can act as a lewis-base and coordinate onto the Cr ( lewis-acid ) and
stabilize it. That will give you the same blue color. You could also use a Nitrogen ( has a lone-pair, too ). So that's why I used the Pyridine. I read that on the net but haven't seen it in action so far. So I descided to try that by myself. That's what I got. I only added a few drops of acid here and got that brown compound. After adding more acid it changed color to the second picture. So I don't know whether it's supposed to look like that but apperently it looks brown-orange in Pyridine while it's blue in Ether and Water.

So that's all for the moment. I will upload some more (non Chromium) pictures soon. Hope you like the stuff above. I had to send all the pictures from my phone to my PC via Mail so I only sent them in the lowest size. If you want any of them bigger just write a pm.

Sasan, the pics. look awesme!
Looks like you'll be having fun arkoma :) I'm setting up my first distillation rig, and asked for the last piece for mmy bday. Should get here on mon. So excited, I'll take a pic. when I get it!

Oscilllator - 6-7-2014 at 19:07

arkoma why have you got the vacuum take-off adapter stuck to the top of your condenser there? Seems a bit odd.

arkoma - 6-7-2014 at 19:38

I generally use shoe strings to secure stuff; the take off has the vacuum titty which helps make a more secure attachment and its just gotten to be habit

kristofvagyok - 8-7-2014 at 22:07












Something adorable: an /almost/ brand new model reactor. Since every part of it is monitored/controlled, reaction conditions (temperatures, pH, concentrations, stirring speed ect.) could be easily set and experimental data for calculating reaction kinetics could be obtained in no time.

What does this means? We could make the best coffee ever with this.

More pics at: http://labphoto.tumblr.com/

The Volatile Chemist - 9-7-2014 at 11:01

Wow. I'm guessing that cost a lot...
How much? Just curious. Does reactor two mean you have a first one?

THIS is mad science LOL

The Volatile Chemist - 12-7-2014 at 06:54

Looking good arkoma! I just got a distillation flask (I already had a condenser :)), so my lab is looking better than ever. For the first time ever, I got an acid stronger than vinegar :P My parents let me buy some 93% drain cleaner sulfuric acid. Sure, it has impurities, but oh well :) I'll post some pics soon! BTW side note, you can 'purify' sulfuric acid by distillation, right? My sulfuric acid has dye and corrosion inhibitors in it.

Zyklon-A - 12-7-2014 at 07:13

You can. But don't. Distillation of conc. sulfuric acid is one of the nastiest distillations you could ever do.
It's certainly not one of the first distillations one should do.
And actually, I'm not even sure how possible it is without a vacuum...
It boils (as I'm sure you're aware) at >340 degrees C.

arkoma - 12-7-2014 at 08:12

@volatile listen to this^^^^ sharp young fella. An easy, albeit somewhat dangerous, distillation is starting fluid. I needed the heptane out of it, the diethyl stills off with nothing more than your hands wrapped around the boiling flask (yes, I saved the ether LOL). Pretty much pure n-heptane left behind

Edit--removed the yelling lol

[Edited on 7-12-2014 by arkoma]

Mailinmypocket - 12-7-2014 at 09:47

Drain cleaner sulfuric acid isn't worth the trouble of distilling. The corrosion inhibitors rarely interfere with the chemistry being done with drain cleaner grade anyways. Adding a bit of 35% peroxide can clear it up a bit, as far as corrosion inhibitors go- not sure.

Anyways, this is for pretty pics, not random pics!

*edit* THIS is one of the nastiest distillations you could do. My god what a horrific mess that setup could make.

Chlorobutanol, made out of boredom related reasons:

Actually, chemical names do not need capitalization! Even myself working in the industry somehow never learned that until coming here. I always thought "it's it's name so, capitals!" But nope - Chemical names do not need capitals unless they start a sentence, whoa! ;)

ya did notice my "mood", didn't ya? They are great for bases more so than acids though due (I think) the chemistry of the anthocyanin molecule--it changes color by picking up and shedding hydroxyls. Petunidin so far is my personal fave.

LOL arkoma. Nice pictures though. What about diluted sulfuric acid? I just want to get rid of the pink-red dye. I tried to make HCl by reaction of H2SO4 and Calcium carbonate. I think I added too much sulfuric acid (I diluted it to 8.8 mol/L approx) at too low concentration. I think it might have made *some* HCl, but it still made some calcium sulfate when mixed with Ca(OH)2. It also turned the pink-red dye yellow. I must have chlorinated the dye, lol.

How do you make HCl with sulfuric acid and calcium carbonate? There's not a single atom of chlorine in that entire reaction!
Also, can't you just buy some decent HCl at your local hardware store? They have it near the pool stuff usually, and it's a lot easier than making it, unless of course you're just trying to for the fun of it.

Very nice picture Mailinmypocket!

Do you have or know any practical use for bromo-caffeine? I have a lot of caffeine and no practical use for it, and the means to make the bromo variant out of it.

I found it promotes aldoximes to nitriles (Sigma), but nothing really comes to mind still.

Do you have any means to test the conversion of the caffeine? (assuming you started from caffeine).

No, I got a nifty little 125ml pyrex sep funnel yesterday in a gift box---and had about 60ml of diethyl ether squirreled away. Extracted it from "el cheapo" kroger artificial vanilla flavoring. Ethylvanillin was listed as the flavorant. It's weird cause it smells kind of "peppery" to me.

Thank you :)

As far as making 8-bromocaffeine I dont have any practical uses for it. Mainly I was just desperate to do something with the 100g of caffeine powder I have had kicking around for years. For checking purity I will depend on the m.p. - I have recrystallized the product from ethanol and am waiting on the beautiful crystals to dry and will do a mp on it afterwards to see what the outcome was.

I got the procedure from this document:

I think I'll use a picture of it once its dry on the wiki. I'd use this one, but it seems like a dry version would be more accurate.

I know different lanthanide oxides are used to stabilize the glass, especially to increase alkali resistance. These must be terrible for use for UV photography.

The interesting is, that the older full metal El-Nikkor 80mm f5.6, what is a highly recommended lens for UV photography (http://photographyoftheinvisibleworld.blogspot.hu/2011/02/uv...) also fluoresces under UV light. The front element has a strong blue and the rear element has a faint green fluorescense.

I haven't gotten around to re crystallizing from ethanol yet, still drying over NaOH. Looked decent given that it started with only 1.5g of 3-nitrobenzamide. I'll report back soon, I want to recrystallize very slowly to see what kind of crystals this will make!

Looks cool. Did you make the chlorate?
My sodium chlorate cell is a pain to work with. The yields are never great, and it takes a long time. KClO3 is easier.

Is that thermite?
What composition?

Mailinmypocket - 27-7-2014 at 15:25

Could it be some composition wrapped in aluminium foil and hit witnh a hammer? I've seen this done with an organic peroxide before...

Zyklon-A - 27-7-2014 at 15:31

Yes, I bet that's what it is. The shower of sparks look like a thermite, or a slow burning yellow flash powder.

It was just the decomposition of bleach by heat, that's all. No electro. cell. I've been meaning to try making one, though.

Dear zyklon-A it's composition was (it was kind of flash powder I guess): Potassium permanganate(24 grams) + sulfur (7 grams) + charcoal (2 grams), I wrapped it in paper shit/paper towel , then hit it with hammer and then boom HAHAHAHAHA (but there was no actual loud sound ,it just bursts into flames! without producing sound of explosion) :-)

any kind of organic peroxide,will work ?or we have to use special one?for instance will acetone peroxide wrapped in aluminium foil produce the same effect?

HAHAHA ! homemade magnetron sputter coater !
It doesn't work well though! but looks pretty!

NO. That would just explode.
No sparks, no visible flame. Just a Bang! Maybe some Al flakes will float to the slowly to the ground.

Yes it does.
How'd you make it?

Similar but not the same actually.. Wouldn't recommend doing it though without proper safety shields as seen here

I know it explodes wit a loud bang HAHAHAHAHAHA :-)

Dear zyklon-A I'll tell u soon about its details! for now I've got these pic for u which I designed before I make an actual one!

1- is plexy glass (we use this name for it here in my place)
2- is screw hole , the screw will be connected to part 7 (copper plate)
3- is hole which will be connected to vaccum pomp
4- is screw hole , the screw will be connected to part 6 (sample/substrate holder which was made whit a metal shit)
5- it's just a glass bowl but big one! HAHAHA
6- substrate holder !
7- Copper plate
8 - two ring magnets for helping the plasma to get more dens above those magnets and that area!

but it didn't coated well , I am working on it
and uh , for power supply I used an old MOT! (Microwave owen transformer) HAHAHAHAHA and a Variac

I made it from steel. In the picture, I'm filtering the carbon out of it before I recrystallized it. I then used it to make iron gall ink.

Hmmm. You could perform nucleophilic substitutions there and add different groups :)

I never get tired of seeing the beauty of different things in science especially in chemistry. I recently had to sort through a few of my past experiments and I found some old pictures from back in the day when I just started to document my experiments with fluorescein. The fluorescence still looks amazing....

Your sig's quotes are nice, too. I always like a good chemistry quote :)
Have any more pictures?!?

If you can, upload any photos that may be useful to the Sciencemadness Wiki - we can definitely use them!. You can hotlink your images from there afterwards. Use the tag "img src="{insert source here}" width=800" for this.

Not too many things quite like fluorescein, I always wanted to try my hand at making some for kicks. Thanks for sharing. I used to talk to a really cool person who turned me on to chemistry and they had some really cool pictures of the stuff.

Just finished my DIY TLC lamp, so I'll have to post some pictures of some things fluorescing soon as I can find a camera to borrow.

Cadmium sulfide- solid sodium sulfide was added to the right side of the dish, cadmium sulfate on the left. Such a pretty color :)

Chorination of an organic compound with elemental chlorine and UV-C light.

The glass on the left is a quartz tube with a low-pressure mercury-vapor lamp inside it what emits UV-C light with a maximum emission at 253 nm. Normal borosilicate glass would absorb this light, but the quartz lets it through, so it could cause the chlorine molecules to break and form highly reactive chlorine atoms.

The greenish-yellow light at the other glass joint is caused by the fluorescent reaction products.

Ferrous sulfate is one of my favorites, along with Arkoma's copper acetylsalicylate. Do you have a write-up or recipe for making that ink? I know we have a thread for it but I'm too lazy to go through all of that. I'm hoping to make some for a friend who enjoys calligraphy.

Oh, and Hegi, great pictures, both the landscapes and the minerals. I've really got to get around to visiting Central/Eastern Europe, for the nature if nothing else.

Well, the ink that I made isn't the best stuff. I just kinda threw it together, loosely basing it on fiberdrunk's California live oak gall ink recipe, which is linked in that thread. The differences with mine are that I used Texas live oak galls, because that's what I have, and more ferrous sulfate, because for some reason it wasn't complexing properly with the amount used in the recipe. It's also still quite runny, despite stirring in several heaping spoonfuls of acacia gum. Maybe it just needs more, I don't know. I also don't have anything to use to write with it, other than glass stirring rods, so that probably also contributes to the messiness when writing.

Oh, all right. You said it so matter-of-factly I thought this was something you were experienced with. I'll probably have to do a fair amount of experimentation when I finally get around to it.

Actually I do have a few more pictures of some experiments I've conducted over the years. Some pictures are okay and some not so much.... but I've started a blog pertaining to my overall experiments in chemistry and if anyone wants to take a look I'd be honoured http://lab-chemist.tumblr.com/.

Apart from that here's a few of my pictures from one of my experiments. This was the chlorination of toluene to yield benzotrichloride, sadly I only got it to produce a mixture of benzyl and benzal chloride but I still count it as a success considering the sun was my uv-source and a mirror was improvised with some aluminum foil to help focus the light.
