I have to admit, the timing of this video is rather comical. Just yesterday, 04/28, we attempted to make ferrocene in my advanced inorganic chemistry class using what was supposed to be FeCl2.4H2O. However, based on the color of the majority of what was in the jar, most of the compound added was most likely FeCl3. That wasn't our only problem in the day, for instance, the lab we were using from MIT called for 15g of KOH, but we ended up adding 60g because we couldn't get the mixture of KOH and 1,2-Dimethoxyethane to stay in a slurry. Anyway, this would have been very useful in order to get pure FeCl2 to react and eventually make ferrocene, and it was rather comical to see the day after we needed FeCl2. Thanks for the videos, keep up the good work.
I really love the videos with tips and tricks to get around a problem. As a newbie to chemistry I'm really impressed with you skills. It really take som smart thinking and knowledges. Thank you for another video.
+Doazic Good glassware, especially glassware with ground glass joints, are designed to take vacuum. Vacuum distillations would be impossible if we couldn't use vacuum on them.
+99 problems When using ground glass joints silicone grease can be applied to prevent seizing as well as provide a better seal. When i use grease i've never had a stopper get stuck.
When I saw the grayish anhydrous ferrous chloride it made imagine it was the surface of a hellish lifeless planet with a toxic atmosphere. I swear inorganic salts can create exotic imaginary landscapes
Hi, Thanks for your great effort, I did the same experiment but I've obtained a green compound. I had to protect it under inert atmosphere because it started to turn brown/red, I guess that the green compound I've obtained is the tetrahydrate one, is it possible to dehydrate it to obtain the pale buff-colored anhydrous FeCl2 ?
Sorry for my noob question, but are you using a cupcake paper to filter? If not im sorry but it really looks like that, I wana know cause we have some and maybe I can use that ..
Can i dry while bubbling with nitrogen? Without distillation? Or maybe bubbling the solution for a long time with nitrogen and then using a Rotary evaporator? Thank you
I love watching your videos! However, can i just put the solution of ferrous chloride out side and let it oxidizes, and obtain the ferric chloride salt by evaporating the ferric chloride solution?
Im doing a fun experiment using electrolysis, Im wondering how to dissolve the anode iron nail quickly. is there a way to dissolve it completely faster.
Is it possible to dry the hydrated ferrous chloride in a microwave oven? Just use a plactic container with a cap, and a small hole in it to let the steam escape. Almost no air is able to oxidize the iron then, I think. Or is there something else that keeps this from working? Also, I don't think it will get hotter than 100 degrees C, because when the water is gone, the iron won't heat up anymore, which keeps it from decompositioning.
+marco23p if the ferrous chloride was freshly made and no air was exposed while you put it in the plastic container then i suppose that can work. I'm just afraid it might get too hot and melt the plastic since the ferrous chloride salt is conductive and might absorb the microwaves and start heating.
Aren't you worried that the nails will scratch the hell out of your flask while using them as stirrers? Seems like a good way to cause a huge mess in the lab later.
Once again very good! Just one thing; at the very end I ALMOST got to hear your real voice I think. Seems the voice scrambler you use was going wonky. Thanks as always Nerd.
I used steel wool and the resulting cloride was very dark green, so I left the wool in for another day and it turned dark blue... I don't think the steel wool I used is pure enough...
Could I make CaCl2 anhydrous for dry in a desiccator with this method?: First I make Cl2, and I do it pass into H2SO4 to dry any rest of water. Then I pass this Cl2 dried in methanol with CaO. Thanks you a lot!
I'm making a mass amount of this to purify water for drinking. Is this the same recipe? 57 GRAMS OF IRON, 300ml OF METHANOL AND 200ml OF HYDROCHLORIC ACID
wait drinking water? this is designed to be used without water. If you just want ferrous chloride you can add iron to acid and skip the methanol... But even then, i do NOT recommend using nails. They could contain other heavy metals like lead or chromium which are not healthy at all. You need a source of a ultra-pure iron fit for human consumption.
could aqueous ferrous chloride be dried under an inert atmosphere to keep it from oxidizing, or does it decompose/react with its water at the required temperatures?
+Robert Szasz if you can do it under inert atmosphere that would be a lot better. Although if you were working on that level you probably aren't an amateur and can afford to buy anhydrous ferrous chloride directly :)
It's almost always cheaper to buy common chemicals, but welding grade gasses are pretty cheap. If you haven't already done so making an oxygen scavenger/ gas dryer the low cost but high labor way could be very interesting.
Here's how to make ferric chloride anhydrous: Get some iron and hydrochloric acid, then add some methanol to the mixture. Then react it with some hydrogen peroxide, oxygen, or chlorine, distill off the solvent, and insulate it to prevent moisture getting in. That's how to make anhydrous ferric chloride.
not a very nerdy question, but why do you alter you voice to make the tone a lot lower? (Assuming you do and your voice isn't actually incredibly deep)
+Nashyj495 He doesn't want people to recognize him, is more or less what it comes down to. The company that he works for doesn't like these kinds of video, from what I've heard.
Guys wondering if you could help in the sand casting world we need bentone 34 to make k-bond casting sand it's an oil based sand instead of green sand problem is bentone is really hard to get your hands on if you could do a video on how to alter bentonite clay into bentone it would be really appreciated I have no idea where to even start
+ficolas2 bentone 34 is made from bentonite clay something about changing ions or the structure of the clay I don't know chemistry all I know is bentone 34 is made from bentonite and I wanna know how to do it to make oil bonded casting sand
I guess you used square head nails because they are usually very old and are more pure iron and not steel. (too bad, usually they are work money to collectors if they are in a reasonably good shape.)
Dear nerd rage I am looking to make polypeptide bonds between 2 amino acids at home, could I use HCL to hydrolyse the 2 amines and is there a way to couple the functional groups with easily available reagents? Thank you so much.
nerdalert226 They're the same thing. You need licenses to buy the toxic reagents. Hydrolysis refers to the cleavage of an amide bond not the formation. You're thinking of an entirely different process where the formation is much harder to achieve.
Laboratory grade glassware (typically borosilicate) has a very low coefficient of thermal expansion so it's very unlikely. This is one of the reasons lab glass is so expensive.
That can happen yes. As long as it won't influence onward synthesis you can use silicone grease to help prevent the joints jamming under reduced pressure. Alternatively use a hot air gun on the joint. Options if these fail to work tend to get messy.

Does anyone know if the same reaction can be performed in ethanol or acetone instead of methanol? Just worried about methanol fumes and general safety, plus I have a pile of ethanol and can get acetone but methanol's not very accessible.
+Erika Sandstrom You could use water in the reaction as well, but because the boiling point of methanol is much lower you can boil it off much faster when you need to.
I admit I don't know too much about chemistry, but here you're using what you refer to as "iron nails." Aren't these nails actually a steel alloy? As a source of iron, wouldn't something like sand cast iron pipe be a more pure source? It's easily broken up with a hammer.
+Barnekkid Ironically (pun *very much* intended) cast iron is not pure iron, it contains much of the same alloy elements as steel, except much more carbon (>2%). Plain carbon steel, such as old nails, contain only very trace amounts of elements like phosphorus, sulfur or manganese, I don't think it's a big deal. Very pure iron can be obtained from iron transformer cores if need be (and specialty metal retailers, it's not unobtainium).
+Fatih Enes Kuru your equation is unbalanced, even then, there is no reason it should occur, the acid would react with the iron and release hydrogen gas far more easily than reducing methanol
Pretty sure it's his actual voice folks. What would he gain by distorting it? He's an educational channel, and his videos are high quality. Deep voice people do exist.
