Hi and thanks!! A+ interchange is quite good, I am pleased to have sponsorship with them!! Also thanks for those inspirational words! NurdRage and NileRed are two of my biggest references! In fact I started studying chemistry at the universit, along with other things, because of their videos! I just loved the way one person can mix reagents to change matter properties and give it helpful uses ;D Here is the link to my organic kit if you want to do some research or even purchase ! : www.dixonscience.com/product/48385/Organic%20Chemistry%20Kit

I usually don't like text-only narration but here the combination of soft ocean wave sounds, the steady clink of glassware and hum of the vacuum pump, and various camera angles was fantastic. That *and* the scientific detail just made it awesome. The only thing missing was the clip of Pink Floyd at then end...

Haha thanks for your comment! Really apreciatte that! Only for that i think the next video will have a pinkfloyd short sound at the end ;D

@@Glattuh yes on Pink FLoyd

​@@Glattuh cought that! how about some obscured by clouds or echoes 🤔

Yeah I think Lumix is a great camera brand and they are doing things really really well! Not sponsored by them yet but hey, who knows :D Thanks for your comment!

Yeah that is another way, but if the use of solvent can be skipped.... much better! Thanks, nice to hear you saw me from there!

Thank you very much! As far as I know the mechanism of oxidation with permangante is not well known. Thanks for the advice, I wish I had more resources to film it in better conditions :D

Thanks!!! Expect some music in the video hehe

Thanks for the feedback!!!

Thanks! Indeed, I really love it!

Ok I see what your question is, I was honestly a bit lost at the first read. Let me explain: A stoichiometric reaction shows how many molecules react of every reagent to produce certain molecules of product and byproducts. Who speaks of molecules so speaks of moles too, they are the "same". That doesnt mean that I used the stoichiometric amounts to get my reaction mixture!!!! That a veru different thing and this is the key of your question. I added toluene in huge excess. We chemists speak of what we call the limitant reagent, which in this case is the permanganate. And it is very convinient!! Permanganate tends to be very reactive and the byproduct is insoluble in water so I added a huge excess of toluene to ensure all of the permanganate reacts. The excess toluene, as you saw, is simple to be separated from the reaction mixture. Also excess toluene forms an azeotrope with water and increases volume of the mixture, as bigger quantities are easier to work with. You can think that toluene acts both as reagent and solvent (partially, as there is water too). Hope that helps!

Hi! Thanks for the comment! The sound is coming both from noose fron the camera and white noise added in editing. I made that sound myself as I once used the sound of the sea from a YT video and have copyright issues.... ;}

Thanks!!!

Thank you for your time! Nice to hear you enjoyed it!!!

Thanks! All the footage was recorded with a Lumix FZ1000, a non interchangeable lens camera. Now I upgraded my quiment so if you like the quality of this one check out my latest two videos :D Thanks for commenting!

Thank you! I dont quite understand your question... The toluene is oxidised by the permanganate as it is converted into benzoic acid. Excess toluene is added to ensure all the permanganate reacts.

I think most of the time the order of addition only matters in more energetic/exothermic reactions.. like with the heat of enthropy when you add acid to water vs water to acid... sorry can't provide the math..

Well you are actually right! I just sometimes feel so confident handling glassware that I dont even imagine that something bad may happen, which it could alsoo!! Many years of experience and never had an accident hehe About the heating mantle... Yes!!! I am pretty happy with it. On the other hand I had an issue with it and it is the following: without the thermal probe the temperature set is not the actual temperature of the plate. And also my sponsor wants me to say it out loud, let me explain. If you want to boil water and set it to, let's say; 105ºC and erlenmeyer with water will never boil. You have to set it like at 200ºC or even more for a faster boil which is a bit dissapointing even though once you get used to it, its's just ok. With the probe also it works 100% well! The temperature rises pretty fast and precise! Again and as I said, I am pretty happy with it. The materials used and performance are extremely good and durable. I have done many experiments on it and it always have exceed the expectations. If you want to research more follow or even purchase one the next link: www.dixonscience.com/product/47970/Hotplate%20Magnetic%20Stirrer Thanks for commeting!!

​@@Glattuh I think better worry than sorry. The neck grabbing seems to be more comfortable in case you would need to transfer hot liquids. I meant a mantle, not a plate. I've found it already, unfortunately, there are no sizes I would consider to purchase (2000mL), and that link you have shown to me contains a very expensive item - for that price you can get a full set for distillation with the heating mantel for round bottom flasks. On the other hand, I rather do not need a hot plate (hydrodistillation, Soxhlet extractions). I think the temperature sensor on the device like a hot plate or heating mantle is not the best idea - you always suffer some losses of energy, so the temperature should be monitored in the place where you want to have the desired value. Thank you as well.

Ni ce to hear that, thank you! Unfortunately I dont record the sources when planing my videos. I pretty much use public data to do them. Also I can say that pretty much 100% of my procedures are by myself so to say. I may replicate other people work but I perform them in my style. Also, most knowledge shown, for example in this video, comes from "me". If you have any questions feel free to ask me here so people can see it or privately. You can see my email here: kzfaq.infoabout

The info behind all my videos is a mix of quick looks to papers, wikipedia, databases of chemical compounds and videos on YT... Sorry, I cant provide them all. If you have any question feel free to ask!

Hi! Many of you are asking about the calculations/procedures. In most cases I just create them to fit my necesities for the video. I am starting to think to build a webpage in which we can talk more deeply about some videos/questions you may have. I am still evaluating this. Thanks for your comment!

@@Glattuh merci beaucoup

Hi and thanks! It is possible but not worth it at all, less than trying to get benzoic acid from toluene. I can imagine at least 2 ways of doing that, and both requires more energetic materials (also more expensive and difficult to get). If there is any interest in doing that is only for academic/entertainig purposes. If you are interested in toluene it can be get cheaply at drug stores as paint thinner. I got mine a while ago for exactly 6,29€ a liter.

@@Glattuh oh, ok thanks for your advice!

Hi! Probably you just need to replicate the conditions as in this video. I am sure p-nitrotoluene is a liquid too, inmiscible and less dense than water. So by becoming in contact with excess KMnO4 solution you will get the same reaction going :D

p-nitrotoluene is melting in 55 °C, first melt it, prepare KOH + KMnO4 solution but use little water as you can. Water has H+ ions as well, and they consume KMnO4 electrones. KMnO4 absolutely use with KOH... that would be a rocket.. %85-90 yield. Thanks for video.

I asume you refer to the neutralization step (as I didnt use sulfuric but hydrochloric instead ;D). The reaction is quite simple: 1C6H5COONa (aq) + 1HCl (aq) = C6H5COOH (s) + NaCl (aq) Hope that helps

In theory, yes! I do not really know the experimental conditions though ;(

Hi! Im having problems with this coment, inmediately after responding you it autodeletes. Find my email on the channel description (bussiness contact)

@@Glattuh I think I´ve found it. I´m gonna write my requests right away. Hope I didn´t forget anything or made any mistake.

Hasta la fecha los he conseguido en una drogueria cerca de donde vivo en Madrid. Es una tienda muy famosa entre los químicos locales, incluso tiene historia O: Si estás interesado te dejo el siguiente link hasta su página oficial :D manuelriesgo.com/
