Okay, this is chapter 11, number 12.
00:25
So how is the misability of a liquid with water related to its polarity? so some of you might be able to guess this, but polarity of water, what we're talking about, first of all.
00:41
Water is a polar molecule.
00:49
Water being a polar molecule has a dipole moment.
00:56
And in general, dipole moments try to interact with things.
01:01
Dipole moments are a little bit like having a charge if you have a dipole moment, except the most favorable alignment of two dipole moments.
01:14
Well, actually, the most favorable interaction a dipole moment can have is alignment alongside another dipole moment of the opposite direction and magnitude.
01:27
So, for example, like that.
01:29
So in the case of water, that dipole moment is facing one direction.
01:41
And you're going to, we're going to want it to probably align with another dipole moment.
01:48
So some other molecule with a dipole moment.
01:53
So the molecules which do that best, which interact with water most favorably, and in a sense lower the energy, of interaction are other molecules which have dipole moments.
02:10
So that tells us that most miscible, so most miscible, most miscible liquids with water will have polarity...
