@@elitearbor Yeah, it's definitely possible to precipitate forks from a solution of K2Cr2O7, but it requires a stoichiometric amount of reagent-grade wishful thinking. If you use the wrong amount of wishful thinking, then you get spoons or other undesired products. 🤪
As a child in the early 1960s I used potassium dichromate for DIY pyrotechnics, Fifty years later I got bladder cancer - a common result from exposure to hexavalent chromium, Fortunately, caught early (I was pissing blood) and operated on quickly, a success. Not everyone is this lucky.
I worked at a hazardous waste recycling plant for 5 years, and our main task was to take in waste chromic acid and treat it to turn it into trivalent chrome filter cake. I have seen more of that orange stuff than I ever wanted to, lol.
If it’s orange you’re fine, that chromic green I am ashamed to know how it tastes (because I have had poor lab safety in the past and bite my finger nails)
Just wait until you see the (in)famous ammonium dichromate volcano experiment. It spills dust everywhere. Looks pretty though, if you can ignore the potential health hazards. My high school chemistry would regularly set off giant piles of it on the table top. Back then, there wasn't really much awareness of safety protocols. I am glad we have moved on.
as a fellow amateur chemist, I find it super weird that you consider sulfuric acid to be wasteable on such a project, while considering hydrochloric acid precious. In Australia, HCl is sold by the bucketload to consumers at a reasonable price, ~$5-10/L while sulfuric acid is a pain to get, I bought a 5L jug of it a few years back for ~$80, so $16/L, but now it's basically impossible to get unless it's dilute battery acid, which is ~$20-30/L so for concentrated, it would work out to $60-90/L, presumably because of potential fears of misuse.
If you mix sulfuric acid and table salt (sodium chloride) you get hydrochloric acid, so if you have sulfuric acid you can always make hydrochloric acid because you probably have table salt in your home.
Where in Aus are ya? I'm in Melbs, and Iget 98% H2SO4 from a local chemical cleaning supplier super easy. I think its $60 for 5L where I get it from. But yeh lol gotta love the $20 5L bottles of bunnings HCl haha.
in Europe, or more precisely in Poland, you have to fill out a declaration of use of such things as strong acids, and if he wrote that he wants to use such an acid to create highly carcinogenic, toxic, and lethal chemicals, they certainly will not sell him such things, and if he lied in the declaration (I do not know, to create simple reactions) during a possible inspection could impose on him a large financial penalty or even imprisonment
@Amateur Chemistry Good to see you liked one my suggestions for a video!😊 Also I would like to say there´s a better way to convert the chromium(III) hydroxide present in the chromium and iron sludge into potassium dichromate: 1 - instead of calcium hypochlorite, use sodium hydroxide and hydrogen peroxide to make sodium chromate 2 Cr(OH)3 + 4 NaOH + 3 H2O2 = 2 Na2CrO4 + 8 H2O 2 - After that, you can purify and separate the chromate from sulfate ions by precipitating them as calcium sulfate 3 - After filtering and washing also the chromate from the calcium sulfate, add a solution of a soluble barium or lead salt to precipitate yellow and insoluble barium or lead chromate 4 - After cleaning and drying the precipitate, it can be converted into potassium chromate by first reacting it with a stoichiometric amount of sulfuric acid to convert the barium / lead chromate into barium / lead sulfate and after filtering and washing the precipitate until the filtrate is colorless, just react the filtrate with potassium hydroxide, carbonate or bicarbonate to make potassium chromate (PbCrO4 / BaCrO4) + H2SO4 = (PbSO4 / BaSO4) + H2CrO4 H2CrO4 + (2 KOH / K2CO3 / 2 KHCO3) = K2CrO4 + water (and carbon dioxide if carbonate or bicarbonate was used) 5 - Finally, instead of sulfuric acid, acetic acid can be used to convert the potassium chromate into potassium dichromate since potassium acetate is way more soluble than potassium sulfate, which will help you obtain more potassium dichromate and of higher purity.
Uhh great process for someone who can get h2o2 but us eu chemists can only legally own 12 or so percent h2o2 and that to unreasonable prices(more often just 3%) wich would make it rather costly and a way to huge volume on that scale
@@Amateur.Chemistry I have also heard that calcium chromate is like calcium acetate because it´s solubility decreases as the temperature of the solution increases. So, if I´m not mistaking anything, it has inverse or retrograde solubility.
thanks for making a vídeo about shiny metallic chromium and stainless steel, something thats so interesting to me for some reason. waiting for polands nilered CrO2Cl2 !
this channel has helped me learn so much. I now am able to follow some of your calculations and understand some of them! please never change your content style! please! you do such a good job and seem very knowledgeable in your profession, and I think youre also really funny
Looks very pretty through the screen. I can only imagine what it looks like in person. I might never know because I will not be making it any time soon, if ever!
Hahah hell yeh. I'm a chemistry nerd (by hobby) and taxidermy artist (by profession), and do this every couple of years with all my used scalpel blades. Gotta love that evil orange chromate!! I usually keep half as chromate and reduce the other half to chromium 3 to make chrome alum :P
@@RossRadford I use a LOT of scalpels for skinning and preparation work. Probably go through 100+ blades per month, and all my used blades go into sharps disposal containers. Once I've got all 3 of them mostly filled, its chemistry time haha. I used the chromium and iron extracted from them to grow a bunch of different types of crystals.
In my days of wet chemistry, I would frequently clean glassware in chromium trioxide mixed in sulfuric acid. Never used for NMR tubes, those got sulfuric acid and concentrated hydrogen peroxide solution.
If u want to dissolve iron faster in an acidic solution, bubble air through it. The air will oxidize dissolved Fe(III) to Fe(III), which then oxidizes remaining metal to Fe(II), which is a much faster reaction than dissolution in acids.
In high school I acquired some potassium dichromate in order to darken some mahogany chairs I made. I never knew about the hazards and just painted it on without any protection. 30+ years later and no issues. I'll count that as luck rather than evidence that the dichromate isn't that bad.
"Chrom" was one of the gods in the nostalgic Conan, the Barbarian, movies from the 80s, although the name is derived from the Greek "χρῶμα (chroma)" meaning "color".
I once used electrolysis to decompose a fork. carbon elektrode and Epsom salt in the electrolyte. So i didn't have to use the acid. I also got some nice sodium dichromate back then.
On my school on the lab we use potassium dichromate every lesson, I questioned my teachers if its carcinogenic and they say no, i think they dont have a shit about our security, on a lab full of teen fools, with dangerous chemicals and they dont mind
I work long ago in a scrap yard and to test witch stainless steel we have we put a drop of nitric acid on it and pass 12v through it and of it turned pink that means there's molidinum in it
There is a process to make normal black and white film reversal film using dichromate. Reversal film is when you're taking a negative image and making it a positive. Used when you want to project it. Not used much anymore in the mainstream but there’s a very active film photography community that definitely nerds out over such things, myself included!
we have the opposite issue now the teachers have a heart attack whenever an organic solvent isnt handled under a fumehood i mean being too careful is better than the alternative
@8:50 A cheap electric heating pad meant for humans and/or pets would work better than the Sun. And it won't get hot enough to melt the plastic, because they only get hot enough for human skin to tolerate.
You know that conc sulfuric acid allows you to make your own hydrochloric acid right? In fact, you can VERY easily make almost every other common acid in high yields if you wanna put in the time
I can just see two forks waiting for the day some housewife purchases them and these 2 forks are long time pals see! And the one says to the other dont worry! I think ...yes!!!! Rejoice were being sold!

OH GOD THE PAIN!THE PAIN! THE PAIN! ........... nice huh?😢
I would love to see you attempt making the ferrate ions, as they're some of the best oxidizers and also pretty beautiful. There was some interesting thread on science madness about it.
Does it affect plants? I assume it generates reactive oxygen species at the very least. Chromium metal is suppose to be good for organisms, certain oxides however....
If you were to do this again you might use carbon electrodes and pass a current though the solution and through the forks at the anode. Iron having a lower reduction potential than chromium means iron will plate out first leaving behind all the chromium sulphate and supher ions to further disolve the whole mass of the forks rather than using up sulpheric acid making unnessesary amounts of iron sulphate that you later turn onto iron carbonate . You could do the same with less sulpheric acid. And using less sulpheric acid also would mean you could have used less carbonate. And everything would have been far easier to filter with less iron carbonate precipitation. Electrolisys would could have saved you material cost, time dissolving the forks and filtering the sludge.

(PbCrO4 / BaCrO4) + H2SO4 = (PbSO4 / BaSO4) + H2CrO4
H2CrO4 + (2 KOH / K2CO3 / 2 KHCO3) = K2CrO4 + water (and carbon dioxide if carbonate or bicarbonate was used)
5 - Finally, instead of sulfuric acid, acetic acid can be used to convert the potassium chromate into potassium dichromate since potassium acetate is way more soluble than potassium sulfate, which will help you obtain more potassium dichromate and of higher purity.

Oh and havent watched the video just the Intro and im curious if the nickel will make it harder in theory yes since acids tha a hard time with V4A i mean i have molten alloyed and casted that and related alloys in too turbine or pump housings for the chemical industry and they were mad too withstand hot high concentraded acids soo there is sametging similar with gold silver alloys and too get pure gold you need too increase the silver content so it cann get disolved
