"A person can make you feel something in 2 months which someone else can't in 2 years" Cognito teaches some of the toughest concepts , which students like me can't understand, in 2 mins Meanwhile our teachers can't do it in 2 months Time doesn't matter, character does.
REMEMBER, the pencil line is drawn to prevent the ink from rising which would hide the correct results of the experiment. The solvent is below the baseline to avoid the spots from being removed off the baseline
That's not true. Chromatography is important to determine the purity, toxicity and other important factors of substances irl. schools only teach us with inks to give us a preview and it is also harmless
@@shamsta21 lol clever but she’s actually trying to make a point .. and by the way I’m a medical student and we are actually learning chromatography as well this shows you how important it is
Been doing chromatography since year 7 and I have come to a conclusion- It is IMPOSSIBLE to make it sound interesting (you got pretty close though so thank youuu)
Got an exam tmrw and was rly stressed out but I’ve been watching ur videos for the past 30ish mins and I am feeling soooo much better about the exam! Thank u sm:))
Thank you so much ! This video is very helpful. I couldn't understand the concept when my teacher taught me. The explanation in this video is very clear and easy to be understood !
Thank You soo much, I tried reading from the textbook but it didn't really make sense without a proper demonstrations or pictures but here you can understand the whole concept just by watching a video.
I did not at all understand chromatography but thanks to your video, I have full understood the concept. Even though I am not in GCSE grades like 10,11,12, I found this video easy to understand. Thank you 😀😀
My teacher is using these videos and putting the links on our homework website for us to watch. I like stuff with chemistry and chemistry explanations.
Thank you so much for this amazing explanation! I have a chemistry exam in 2 days! The pages of one chapter are really long so at times it confuses me. But you have explained really well in these videos and is really clearing all my doubts and confusion! Thank you so much!
This video was so helpful thank you so much 😁❤ I couldn't understand anything from my teacher but you did make me understand it I have watched maybe 10 vids from ur channell and they all were so help full THANK YOU AGAIN SO MUCH ❤❤❤
I have a few questions 1. Does temperature affect the Rf value? Given the stationary phase, solvent, and solutes stay the same. 2. Does the Rf value stay constant with the same conditions but different baselines? 3. Why are there usually some of the solute as a trail when paper chromatography is performed 4. Does the solute eventually just stop? Or can it keep going if you leave it. If it can keep going, can the solvent front change too? Or is it always constant with the same stationary phase and solvent?
This video explains it all....the best video on this topic in entire TH-cam...u explained everything, literally everything in just 6 min...hats off man...this video definitely deserves 1M likes and way more views...keep it up ❤️❤️❤️
I haven't been going to school since it started 3 weeks ago because I've been sick and it was really hard to catch up on all my work especially this specific chapter and this video helped me to understand so nicely!! Thanks for making such an informative video!!
the video was amazing. I am actually in 6th grade but i only covered the simple topics. the video was very helpful. i hope you keep posting videos like this and reach a million subscribers
my mock exam is near so I come to youtube hope to find some thing can help my for review and thank for god I found your's video and I'm confident for my exam now, thank you Mr.Cognito
great explanation, up to now having a great confusion on this topic, your video makes me clear all things to right. Thank you for your explanation.........
This was one of the tops i truly disliked But now ohh yeah am even comfortable to answer any question about it ... Thank you may our Lord bless you I am very elated..😊
I had a question that involved something along the lines of " suggest why this would work in ethanol and not water" I was not sure what the answer would be What would the answer be

This org is a big help for chem and bio thank you so much I understand my work better now
Cumulative frequency = cum freq..:;:;

Great explanation
A great big thank you. Your website is super organised and couldn't be more complete.
I appreciate the small pauses, so one can really soak in the information. Nice video.

This was the answer to one of my tests... Thanks for the help
Very informative! I love how you talk slowly so we can digest the information and understand it even more.
Glad it was helpful Marriane! 😊
Everybody gangsta till you realise this is just dissecting ink for no reason

My teacher: spent 6hours and 32mins to explain this to us and we still dk wt is happening
Cognito: use 6 mins and 32sec to help me get an A in my exam
fr. teachers like to take up so much time to explain. they waste our lives when we can just learn what they teach in an hour, in just a few minutes
Istg teachers explain way too complicated , using technical terms and shit and expecting us to understand it. Like mate, I ain’t sheakspeare 🙄

Anyone get sent here from their science teacher for quarantine?
meh

Awesome video man!!
Thank you! (And a big thanks for taking the time to leave us a comment, it really helps the videos get seen!)
I haven't understood this topic since I first learnt it in in year 9, 2 years ago - until today.
Thank you so much!
Thank you for thoroughly explaining everything and going slow. It makes everything so understandable!
Cognito, only after seeing this video did I become confident that I will get a full 100 marks in my Chemistry exam. Thank You!
did u?

One of THE BEST videos! Makes it so much easier to understand this technique.
I needed to learn this for my upcoming science exam, the video is very well explained and understandable.
Thanks for making it👍
this was one if the only things i didnt understand from the cgp guide so thank youuu
Glad we could clear things up Eloise! 👍

I have a few questions
1. Does temperature affect the Rf value? Given the stationary phase, solvent, and solutes stay the same.
2. Does the Rf value stay constant with the same conditions but different baselines?
3. Why are there usually some of the solute as a trail when paper chromatography is performed
4. Does the solute eventually just stop? Or can it keep going if you leave it. If it can keep going, can the solvent front change too? Or is it always constant with the same stationary phase and solvent?
The way of explaning the things is really is really goooooooooooood
you actually made me want to try it out myself
none of my teachers have achieved that so far
His explanation is the best. Thank you so much!!

Thank you so much for this video, makes me understand more than my teacher, keep up the good work!!!
Using this to show my students our experiment today. Thank you. (they are 5-7 years old, and can already mix chemicals safely.)
this man taught me the thing in 6 minutes which my teacher cant in 2 years
i really appreciate the way you explain topics , i've been watching ur channel ever since i started the GCSE syllabus and its helped more than alot (:
samee
3rd lockdown, here because we can't hear the video from our teacher
lmao yes
watched this before the day of my exam and it saved me 20marks💀
what a great video , it all makes concept crystal clear.
Great explanation. Thank u so much:)
Amazing way of explaining…..I understood in a go…..thank u!
That was awesome and more better than reading books with long notes but not understanding. I will be making my notes now but from ur video.
yoo thank youu soo much i understood this topic in 6 mins, whereas my teacher took nearly an hour explaining this.
You are the BEST, not exaggerating.
the video was amazing. I am actually in 6th grade but i only covered the simple topics. the video was very helpful. i hope you keep posting videos like this and reach a million subscribers
I don’t go to an English speaking school, but this still helped me understand chromatography!!

@Cognito Can you make a video on Gas Chromatography please? It's really needed for us. Thanks.
Thank you so much it has helped me alot!!!👏👏
Thank you sir , you're an amazing teacher , I feel you need to stop leaving certain things out though , but thank you ,help me get out of high school

Really helpful and well explained
amazinggg!!! AWESOME VIDEO helped a lot THANK YOUUU
I'm from India I've learned Chemistry from your videos .
I have really learnt from it, it made my presentation easy👏
This is better than my science teacher thank you
great explanation, up to now having a great confusion on this topic, your video makes me clear all things to right. Thank you for your explanation.........
always looking forward to your videos man
