Hex Chrome 6 (Cr+6) is used in metal finishing of zinc and cadmium electroplating. However it’s part of the RoHS world directive of the 6 chemicals they’re trying to ban for everything man made. Chromium +6 works great to prevent bare steel from rusting but it’s being faded out world wide becasue it causes cancer if injested. They used to coat steel pipes with zinc and then Hex Chrome +6 as the top coat. It leaves a yellow iridescent sheen on the surface of plated steel. In the movie, “Erin Brokovich” staring Julia Roberts, it tells the true story of an entire town in Southern California that suffered greatly with birth defects and cancer becasue hex chrome 6 was used to coat the water pipes of houses. So now in the industry we use Trivalent chromium (Cr +3) on zinc electroplating and it’s not as good a protector as Hex Chrome, but it is safer to handle. ...oh well, so be it.
I'm an Australian and I bloody love your accent Buddy it's amazing! Easy to understand for me and so fascinatingly different. Iv been trying to learn how to say words like you pronounce them 👌 keep up the amazing shows mate!
Chromium in the +3 state forms may colored depending on what it is coordinated to Chrome Alum , KCr(SO4)•12H2O consists of purple cristalls where the chromium is coordinated to six water molecules. If a reductive reaction on K2CrO7 to chromium +3 occurs in water the result is a deep green color as different things are coordinated to the chromium. Many colors are possible with Cr +3 depending on how it is coordinated.
College dropout here! Thanks for making chemistry accessible to us dumbasses through your excellent descriptions!!! Were you my college professor(s), I'd likely have matriculated into an engineering profession; instead I spent 22 years in the Army...
From the audio and video tape era where I also come from, there is "Chromium dioxide" as a known compound that once was around. Because it has magnetic properties. Which is no longer produced so no longer needed to make tape coating out of that meanwhile. Additionally there have soon been Cobalt-substitutes as well because it is cheaper (or in a mixture with chromium dioxide). BASF e.g. has mainly used CrO2 for their Chrome tapes first and then has also moved to partial cobalt substs. Which have been mainly used for videotapes and professional audio tapes (Reel2Reel) as well.
High grade audio cassette tapes had chromium in them. I don't know if they are still made today but BASF made some cassette tapes like those. You need a high quality tape deck to fully appreciate the quality of them. I am 40 years old and still remember tapes getting tangled in audio tape players. It was almost always an unsalvageable mess because the tape is thin and very delicate. It would be nearly impossible to untangle them.
I wake up one morning and think "I suddenly want to know more about chromium because I use it every day." Thank you, internet stranger for satisfying my curiosity.
Watching the chromium scratch that microscope slide made me cringe hardcore as I imagined the ultra high pitched screechy scraping noise and gaaaaahh.... >.
The Hardest Metals in the World Tungsten (1960-2450 MPa) Tungsten is one of the hardest metals you will find in nature. ... Iridium (1670 MPa) Like Tungsten, Iridium is a chemical element that shows signs of high density and a tolerance of high temperatures. ... Steel. ... Osmium (3920-4000 MPa) ... Chromium (687-6500 MPa) ...
You're the best channel for Chemistry, really. I hella appreciate your work. Also, thanks a ton for the subtitles. Although I've watched so many of your videos that I can understand everything you say without reading them lol
I love the chromium, manganese and vanadium for their many stable oxidation states. Change their colors, turn them into powerful oxidants for spectacular pyrotechnic reactions or use them to isolate the halogens from their acids!
I just love ammonium dichromate because it's an orange powder/granulate. Not something one sees every day. Its funny reaction when ignited is another bonus. Almost looks a bit like tea.
I occasionally ingest a fullerite suspension in the search for longevity treatments. You have to mix it in with extra virgin olive oil (I also add Vitamin E) for over a week. They nick-name it "C60oo". In rat trials, they lived almost twice as long on average.
Titanium is on the second list you presented at 6, iron: 4-5, platinum: 4-4.5, and aluminum: 2.5-3. How did you mess that up? Maybe it’s inaccurate as I see knife blade comes in at 5.5; funny I thought that is too vague a description to determine the hardness with any accuracy
The dichromate to chromate reaction is the basis for soil tests for organic (as opposed to carbonate) carbon, which acts as a reducing agent in strongly acidic environments.
well now on I will be watching you closely, but how I wish to see chromium from the ground and gous through all different stages and become useful to different things. wishing you well and always, good luck.
I would have liked if you showed the practical usage of the various compounds. Many historical pigments were created from chromium, and chrome oxide is still used to this day and is the most lightfast of all pigments. It's commonly used by the military for camouflage.
No it's just harder, so it could scratch titanium or tungsten. Like glass is very hard, but not very strong, so you can scratch things with glass, but it breaks easily. Titanium won't scratch chromium, but it won't break as easily under load.
Stainless steel is a mix of materials. Iron, Carbon, Chrome, Nickel, Manganese, Molybdenum, Phosphorous, Sulfur, SIlicone and Nitrogen, for 316L. And honestly, there are stronger steels than that.
I'm a huge fan of your videos. Thank you very much and please keep uploading quality and interesting material like this. Muito obrigado/thank you/gracias/domo arigato/kop kun krap/merci/spasibo!!

*Excellently explained. Easy to follow, and marvelously photographed.*
If you uploaded this video one day before, I could have won the science quiz!!!!!!!!!!!!!!!
so what question did they ask?
What's Hardest metal on earth?....... I think
It was about chromium oxide.
Ooh.. 😃
Shivam Singhal do u remember what is the question about? like its properties, rxns etc?
You're videos are so interesting and educational.
3:30 That looks like a volcano.
Chemistry is awesome.
💯💯
When this channel says it contains some cool stuff … it’s so right.
These chemical reactions are like.... magic or somethin

What an insane accent.Thank you man for this type of visual description.Chemistry is fun now.
Chromium-hardest metal on earth!
Titanium-Am i a joke to you?
Vibranium-Am i a joke to you
Many of the chromium compounds used in this video are carcinogens including ammonium dichromate, potassium dichromate
just as your profile picture
Chromium is carcinogenic.

Elemental chromium and most chromium(III) compounds are not. If it was we wouldn't use stainless steel cookware and cutlery.
Oh okay.
Thanks.
I love the hl2 sounds at the start of your videos
Chromium does corrode but the results of this process is a nearly transparent layer making it appear not to be corroding.
I like your channel. It gets right into the science!

Lots of love from India. Enjoying your many videos. ❤️❤️❤️💖💖💖
The fun quotient is pretty high too 😀
😂👍спасибо
Beautiful! I love this channel!
That was a fun video, thank you Thoisoi2.
Love this channel. Quick question tho, on the periodic table how many points more of hardness was chromium than titanium ?
Titanium has Mohs hardness of 6, while chromium has 8.5.
Iridium wow that's crazy. Thank you
But remember strength≠hardness
Awesome vid as always. This one didn't show up in my subbed feed, it normally would. Just thought you might wanna know
Zee only zing stronger zan zis zubstance would be titanium.
Hey kids, try to say this correctly, in russian !

Plz do on any radioactive material..
(I wish polonium would be there)
He did, Bismuth is radioactive with a half life of 1.9x10^19 years.
Gallium Games ok. 👍👍👍👍
Bismuth is barely radioactive. Most people consider Bismuth a stable element because it is so mildly radioactive.
Even astatine,radium,californium and lead
Well if he uses polonium he can be killed.

Now I understand why is it called Chromium ! It moves all over the chromatic spectre. Beautiful colors.
do cobalt or molybdenum next please!
I dont understand half the stuff you say but these vids are awsome

Pretty reaction with the orange, black, and blue!
Can you bend pure chromium or will it crack?
It shatters like glass when you hit it with a hammer. Bending will break it.
Hardness comes with a price. Chromium is the hardest metal, but probably the least malleable as well
that's why it's only used as a coat, or alloy
ahhhhhhhhhhhhhhhhhhhhh ! makin sense
Go back to School to learn basic...
That ammonium dichromate would make a very realistic model volcano 🌋...possibly set off buy a model rocket ignition source. Great project idea...
What was the Russian thing you said in the video
It said Putin is Great in Russian. All Russian videos must have that message by law.
Lol stop lying
he said USSR is going to reunion
Nice demo. I saw a few tips I could have used when I was a chemistry teacher. And your accent? You should hear my Russian. :)
