This is gonna be on my Document Analysis test in Forensics. All the explanations of chromatography calculation are totally different than what is on my test. We never said what surfaces are polar and we measure in millimeters.
Amazingly explained! This video really helped a lot! You explained the theory very well too... and especially the demonstration through the software at the end! Hats off buddy! Thanks for uploading such a great video!
Thank you for your great introduction of paper chromatography. What is going to happen if polar solvent (water) is used? Is there any different results in the absence and presence of NaCl in the water?
What would have happened if the solvent were water which is polar? A polar ink would dissolve rapidly in the water and would be attracted to be both the traveling solvent as well as the paper right?
So what happens when both the stationary phase and the mobile phase are polar? Will the Rf of the component depend on the strength of the polarity of the two phases? Thank you!
Tonydaninja gaming it's not possiple As like dissolve like So if mobile phase and stationary were both polar they will dissolve in each other And thetechnique won't work I hope you understand and success Never give up 🌵
Strange, explanations differ by video and presenter. Some say the molecules are more polar if they are st the top of the paper, whereas molecules st the bottom are less polar. But here he says the molecules that have low rf value are more polar, and the ones at the top are less polar. What is the correct interpretation???
The result depends on the solvent used. When a nonpolar solvent is the eluent, polar compounds move more slowly up the paper. When a very polar solvent is used, the opposite is true. That said, I would argue that in PAPER chromatography (the solid phase matters too!), more polar compounds tend to sit at or near the bottom. Paper consists of highly polar cellulose.
i am in my first year of college and its truly very very helpful and tomorrow is my practical
🔥🔥🔥
I had no idea what chromatography was supposed to determine until now. Thank you so much!
outstanding lecture. I gained more knowledge from this video than from hours in the lab with my professor.

Thank you for the introduction. I have learnt a lot and you have explained it quite well.
Best chromatography video on TH-cam!!
I saw many videos and was looking for this explanation only
Finally went through your video and got the relevant content
Video is very helpful, theory was explained excellently
Nicely and thoroughly explained. Thank you!
this is so much easy to understand, i rather learn with lots of image while talking more than just words ;)
Amazingly explained nd cleared all my doubts
Exceptional! Hats off to you sir!
awesome explanation!!, Thank youuuuu
Thanks a lot for this informative video.. May God bless u 😘😘😘
Brilliant video
Plz make more videos like this one
Thanks Micheal! Very helpful!!

You simply killed it🙌
Great methods!
Thanks 😘
Thank you.
It was Amazingly explained....
This was very helpful! Thank you so much!
Bro...you are awesome..👍👍👍👍
Awesome!Thanks a lot!!!
What information do you learn about your 2 compounds by running the 2nd experiment where the mobile phase is also polar?
why it is best to use the farthest distance traveled by a sugar if and when the solvent went over the paper?
What would have happened if the solvent were water which is polar? A polar ink would dissolve rapidly in the water and would be attracted to be both the traveling solvent as well as the paper right?
This helped me so much! Thank you!
great vid

i dont like u tony. ur stupid. hope u fail the investigation
wat
Tonydaninja gaming it's not possiple
As like dissolve like
So if mobile phase and stationary were both polar they will dissolve in each other
And thetechnique won't work
I hope you understand and success
Never give up 🌵

THANK YOU
Tell me independent dependent and controlled variable

hi, what software did you use to make this amazing presentation? X_X
I think he's using DoodleDesk imaginaryroots.co.uk/doodledesk/ - but it's for mac only.
Bingo. To record the screen and video, I use Screenflow.

Thank you so much
Thank you for sharing the useful video could you please tell me from where I can get this simulation software for chromatography?
Check it out!

Thank you so much
This is so beautifully explained....I just...I can't....But wait, no. Now I can! xD
Thank-you
thanks tho. That rf value tho
wow
The explanation is in depth, the drawing is unclear.
Anyone else here from Mill Creek High School AP Chem?
No?...OK.
