Why does like dissolve like? 

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!

Absolutely brilliant. Wasn’t understanding this for a while and your explanation was spot-on.

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.

The best explamation I've ever found in this matter. Appreciate your informative presentation. ❤

Had to watch it twice to fully internalize but I got there. Amazingly well done, I learned a ton!

Thank you for your amazing videos!

You’ve come a long way from teaching on paper to this! Your videos are so helpful

Great refresher -- thank you!!

This is exactly what i need, thank you!

That makes so much sense, thank you so much for explaining this.

Yup, I am subscribing to the channel.

Thats exactly what I need 💙

Awesome video, I enjoyed this video Ben! Thank you! 😀

Perfection

great job man

After following ben your channel and watching breaking bad obsessed with chemistry and willing to pursue in this field 🙂

What about temperature-solubility relationship? Why do certain substances (Carbonates) have negative temperature-solubility relationships?

After studying 6 years chemistry .. Now I Realised that NaCl when didslives in water the Na breaks the bond with Cl .

very nice

great explanation thank u man

thank you sir

thank u sir

No live streaming on organic chemistry anymore?

Music is a little loud on this video

Very well explained! However, I prefer the video without the music.

Polarity and covalence ponds dissolve like for like

Excellent lesson. Thank you. (Very annoying music.)
