The high tuition at MIT is worth every penny for producing great resources like this for their students. Thank you so much MIT. Other universities should follow in your leadership.
Just discovered this channel by accident. Thanks, MIT, I really appreciate the effort on your part .Looks like I know what I'll be doing for the next couple weeks.
Yes. Thanks! My school has low tuition too but that shouldnt equate to an inadequate education. Yet, i question whether or not 'they' care if we learn ANYTHING. We recieve ZERO background info on any of the experiments. No practice or informational worksheets, no video, no powerpoint,...nada. It's difficult ot keep up especially with limited experience. Thanks again for sharing! Greatly appreciated.
thankyou very much. I have found this video very useful to me who haven't done the experiment. It help me to clear the messy theory in my mind. It is very kind of you, thankyou very much.
So Arabesque #1 on iTunes just started while I writing my lab report. I paused it as this video begins, and Arabesque is still playing...I was really confused for a moment...
It is customary to cut off sharp edges from the bottom to prevent the plate from developing faster at the edges and forming a U shaped solvent front which you can't read Rf values from. The plate should look like \___/ starting from the bottom line for Rf measurement (e.g where you apply the compound spots) to prevent edges from being damaged or curled up which result in such a solvent front U shape. Or at least that's what I was taught in several lab courses.
I tend to agree. Simply running the unknown against A and B separately should work. The only thing I can imagine is that perhaps occasionally compounds in a mixture bind to each other to give strange results. That would have been picked up in this case by the left -hand plate: if for some reason the A spot in the middle disappeared it may have been 'hidden' within the B spot. One other way around that I suppose would have been to run a plate with A, B, A+B, and Unknown. Just a guess however!
Shoutout to Tufts CHEM53 students!

This MIT material is very good indeed and a great public service. Thank you!

You really helped me know what I will be doing in lab.

Damn this is old. Still, they did a great job explaining.

Wow. That was so clear. Wonderful. Absolutely wonderful.
Great video, thank you!
Thank you for this excellent video.
Nice explaining
Thank you so much! :] It cleared a lot up for me.
Thanks, it makes studying soooo much easier...:)
This is great help!! Thank you so much
awesome video!! and hearing Debussy is defintly a plus :D
thanks, helped with my homework!
Thank you very much
great detailed video. Thank you
Great video, it explains why you do the steps you do in TLC. Btw anyone know what the piano intro. is called? it sounds really good :)
awesome loved it, happy view :)))) keep up the good work please i'll be there watching lol
thanks a lot for this!
@Gurpreetsingh786 it's either debussy or ravel
thankyou very much
@Gurpreetsingh786 it's Arabesque #1 by Debussy :)
Good very good very good
But what is the use of Rf value??
@valeo626 Thanks :)
awsoem vid, just wish it wasnt recored using a shit camera
