- Talking about why polar substances mix together i.e. polar solutes dissolve in polar solvents, nonpolar substances mix together i.e. nonpolar solutes dissolve in nonpolar solvents, but a polar substance and a nonpolar substance do not mix together to form a solution.

I'm a chemistry tutor and I've come up with an analogy for this before - imagine a highly polar substance as a box full of toy magnets (the big differences being molecules are WAY smaller than toy magnets, and the magnets have a magnetic dipole while polar molecules have an electric dipole), and a non-polar substance as a box full of non-magnetic things like ping-pong balls. Magnets will clump together well with other brands of magnets as they attract each other strongly, and ping pong balls will easily mix together with golf balls or marbles if they're thrown into a box together and shaken up. But throw a bunch of ping-pong balls into the box of magnets and they don't have the energy to break the magnets apart and slip into the spaces between them - the forces are just too strong, and the ping-pong balls are not magnetic. Likewise, throw a bunch of magnets into the box of ping-pong balls and the magnets will attract each other, clump together and push the ping-pong balls aside like a bunch of socially awkward nerds huddling together at a party away from the extroverts. Like dissolves like!
You must be a great tutor to your students.
Absolutely brilliant. Wasn’t understanding this for a while and your explanation was spot-on.
Thanks so much! Glad it clicked for ya
The best explamation I've ever found in this matter. Appreciate your informative presentation. ❤
Thank you so much for your kind words 😀
Hey, this was great content, glad to see you back! Might I suggest though to reduce the music audio level, it was loud enough to be distracting from what you we're saying. Looking forward to more.
Had to watch it twice to fully internalize but I got there. Amazingly well done, I learned a ton!
Very cool, thanks!
Yup, I am subscribing to the channel.
You’ve come a long way from teaching on paper to this! Your videos are so helpful

Very cool, glad I could help! 😀
Great refresher -- thank you!!
great job man
Thank you!
Awesome video, I enjoyed this video Ben! Thank you! 😀
You're very welcome! Thank you for your kind words 😀
@@BensChemVideos You welcome Ben! 😄
After following ben your channel and watching breaking bad obsessed with chemistry and willing to pursue in this field 🙂
great explanation thank u man
You're very welcome! Many thanks for watching 😀
thank you sir
You're very welcome 😀
Perfection
very nice
thank u sir
You're very welcome! Many thanks for watching 😀
After studying 6 years chemistry .. Now I Realised that NaCl when didslives in water the Na breaks the bond with Cl .
Very well explained! However, I prefer the video without the music.
Thank you!
What about temperature-solubility relationship? Why do certain substances (Carbonates) have negative temperature-solubility relationships?
No live streaming on organic chemistry anymore?
I'll stream again when I get some free time. Currently all of my time and energy is spent taking care of my family.
Music is a little loud on this video
Excellent lesson. Thank you. (Very annoying music.)
You're very welcome! Many thanks for the honest feedback 😀
