Everyone probably always complements your chemistry skills, and they are impressive. I would like to point out that your video editing and video skills in general alongside your oddly calm and sarcastic narration is really what makes your videos.
Bruh the development in how u create ur work (video wise and chemistry wise) is amazing, the snap chat version of this is a prime example. Great work man !
My gut says that this experiment is hard to mess up. I used purified tap water, and I didn’t really measure anything out, just kind of went with amounts that looks the same as yours, and it still turned out perfect.
+Philipp Kollenz I think it is possible. cool it down to like 1C and it will go super slow. On top of that, increase the concentration of vitamin C, decrease the H2O2 and play around and it might be able to get that long. I do want to revisit the oscillating clock and i will do that soon :)
+GamerGuy ephedrine would be hard to do as a total synthesis. It's a stereoisomer of pseudoephedrine (sudafed) but it has a stronger effect as a bronchodilator than pseudoephedrine. It's sold behind the counter along with the Sudafed products. It's marketed as a bronchodilator for mild asthma symptoms. The brands are Bronkaid and Primatine tablets, and the Primatine has a generic. They were all off the market for a while but are now back on the market. Ephedrine and pseudoephedrine are the same molecule it's just that it has 2 chiral centers so you end up with 4 stereoisomers, 2 of which are l- and d-ephedrine and 2 of which are l- and d-pseudoephedrine. Both ephedrine and pseudoephedrine can be reduced to methamphetamine quite easily (you're just removing the hydroxyl group from the beta carbon and bam! meth) so that's why they're behind the counter and a limit placed on how much you can buy. The limit is actually quite large though. (I'm going off of how the laws are here in Michigan, other states might have stricter laws, and I don't know what the laws are like in Canada or Europe for pseudoephedrine and ephedrine.) You could extract it from plant sources.
This reaction is something like the Lugols test, it happens because the iodine gets inside of the helicoidal structure of the starch (which is a polysaccharide) , the elemental iodine color is blue , so that's why you get that color
Okay here is a story and a half. I was listening to music and Corduroy Dreams by Rex Orange County came on as the introduction of that song was playing I pressed play on this video and damn. I realized that Nile's voice intonation perfectly matches that song (which is in E major btw) so for the future Nile if you ever want to add music to your videos make sure they're instrumentals in the key of E major. 👍🏻
Nice white background! I really like the demonstration when the solution is stirred - the colour appears suddenly and uniformely. (Some people think that this dark-blue colour appears as quick as a night in Egypt, and that's why this reaction is also known by the name "Egyptian Night") BTW, I thought that it's I2 that makes a nice blue complex with starch, but apparently I was wrong.
This is a lot more striking if you chill one of the solutions (I do the starch) before you mix them. The reaction takes a lot longer to start, but when it does, it's so slow you can watch black tendrils form out of nowhere. Getting larger and larger until they take up the whole thing.
i'd like to see this put into one of those soda streams, could really probably prank people on facebook into believing you found the secret recipe for coke
What if you kept solutions a and b right above freezing, then mixed them. Hopefully creating a flash freeze. I wonder how the reaction would change while in fine ice crystal form.
I used spray starch for clothes and it didn't need to heated and was totally clear. Also the vitamin c crystals are the best and they dissolve very easy.
21 people Tryed to drink the " coke " lol my nieces and nephews absolutely loved this totally got them hooked on hanging out in the lab unfortunately almost none of our lab work is exciting to kids and not a safe environmentThanks and I love your clips !!
I have to do some science expirements for a bunch of kids like 6 years. Today I was searching for vitamin c and most of them were either infused with extra taste or those gummies but I found one eventually which was pure powder. I think this will do great
My science/sex ed teacher used this method to explain STDs. Each of us got a glass of clear liquid. ONE glass started with all the necessary ingredients to cause the reaction (minus a pipette of other liquid) we were instructed to intermingle our contents with anyone we chose (or not to intermingle with anyone we did not want to) for two minutes then we were all given an STD "test kit" (the pipette) we were told only one person started with the STD, and if this pipette causes your liquid to change color, you were infected. Class of 40 students, two stayed clear.
Very nice video and good explanation ! Although I have thiosulfate on hand I would still like to know how many grams of PURE ascorbic acid was used for this experiment cause I only have it as a pure crystalline powder at the Lab. Best regards.
The chemical reaction looks great, and a very fascinating observation of the chemical process through a visual frame! I carefully followed your lecture, and I would like to thank you very much for the education, and I was carried away by creativity to perform such an experiment in my laboratory and it really worked, I am amazed :) I had to record and share with the audience and people who know me such a magical effect of chemistry. Now I noticed that the reaction is not reversible, so when the solution turns black, that's the end. So I would ask the question, what needs to be improved in this experiment, in order to obtain an oscillatory chemical reaction with several repeating episodes of color changes, using the same substrates and reactants? I would be even more grateful, although since I am a chemist I will do my best to come up with a solution by myself, but in the meantime, please give me some space and time to try on my own, so if you have a solution for the illustrative reaction, write me the recipe on how to make it, or even better post a new video about it? Thanks bye :)
I have 2,6-dichloroindophenol sodium salt powder... can i use it as an alternative for iodine tincture?? If so.. how can i make it a solution? how many water will i add per grams of the powder? Thanks for the reply mate..
Does anyone know how to change the dark blue back to clear? I saw a demonstration where another liquid is added after the iodine clock reaction and the water turned back to clear. I can't figure out what liquid it was.
What's going on here is that the oxidizer and the reducer are competing to do their particular magic to the iodine. In the end, it's a numbers game -- whichever solution is more abundant will win. If there is more reducer, the final solution will be clear. If there is more oxidizer, it will be dark. So, if you want to clarify it after, add more of solution A.
It'd be cool to see this done again, either here or on the second channel, done in the lab method with thiosulfate. It would be a very useful addition to a lot of chem 2 classes! Most of the demos on youtube suck.
I'm having a moment of deja-vu here...I can't remember if it was a short story, or a plot device in a book, but when I was younger I read some kind of mystery. In order to catch the culprit red handed, they added something to a doorknob I believe, and somehow got a second something onto the suspect's hands. When that individual ended up touching the doorknob, the two components mixed, and some time later caused a reaction. The resulting effect was that the suspect's hand had been dyed with a dark color, similar to your experiment here, allowing the protagonists to identify who had touched the doorknob. So, my question, is it possible to use solutions A and B to set up something similar, and would it dye someone's skin for long enough to identify them? Or did the author take this reaction and build off of the actual science of it for something like science fiction?
What if the solution A concentration is increased and the solution B remain constant, so will the reaction will faster if solution A concentration is greater>
Oh man are you going to see interesting things then. This is absolutely one of the more tame chemical demos. Keep watching NileRed and you'll see some amazing shit.
I actually did this at home and it pretty much worked. I say pretty much because it took about 2 minutes and it very slowly changed from clear to yellow to brown. Once it turned brown then it flashed very quickly to black like normal. Any ideas? I think it could be my iodine tincture.
To me aside form all the fun sciencey colour changes,. my real interest here would be whether vitamin c reacts with lugol's to form iodide..and whether that is a permanent undesirable effect/ state.. I guess the starch has pertinence for those who may ingest a sticky bun at the same time.. is this the purpose of the video or was there some other point?
The coke bottle would make a fantastic magic trick if you palmed it with a real bottle of coke you could really complete the trick I reckon it would fool Penn and Teller
Those chemicals are found in the body, I'm wondering if a similar reaction dose occur in biology. Thyroid hormones, glucose and vitemin c and peroxide production from the cells
Hydrogen peroxide is a reactive oxygen species, ascorbic acid is an antioxidant. Living tissue maintains an antioxidant buffer and if it were to run out that would mean the tissue is in bad shape. That said, human tissue can alter the prevaing oxidation state to fight an infection - the snot-green enzyme myeloperoxidase uses hydrogen peroxide to synthesize hypochlorous acid and literally bleach pathogens. Hypochlorous acid is too strong to be medically useful, but iodine is less reactive and actually used for wound cleaning. The stuff you get in a drugstore usually isn't sterile and is only intended for superficial cleaning, but sterile povidone iodine is sometimes used for deep wounds or during surgery. Iodine is very well tolerated - doesn't burn like the lighter halogens - and the biggest medical concern is elevated iodine levels that can interfere with thyroid activity. And it's an oxidizer and it wouldn't be good to have it in your body constantly. Oh, one last gross bid of household chemistry. The myeloperoxidase in pus or angry sinus-infected snot can be detected by exposing it to household grade peroxide. It makes a faint but nasty bleach odor.
would this reaction work if my vitamin C source were liquid soft-gells with 20mg each, manganese sulfate monohydrate and fish oils mainly? should i need another method to separate the rest of the unwanted chemicals?
Can't for the life of me get it tp go back to clear. I followed the instructions to the letter three times now and have always gotten a dark liquid change, but it never goes back to clear
