Okay, what type intermolecular attractions would you expect to observe in the solution between the calcium fluoride and the water? so we can look at them.
00:20
So for water, it's a dipole molecule, right? it has, it's a polymer molecule.
00:26
And for the calcium fluoride, when dissolving the water, it becomes calcium irons and fluoride.
00:33
Irons.
00:35
So now we can look at what kind interactions they will have.
00:40
So apparently, if you have interaction between water and the water molecule, if we draw the interactions, of course, the first one, it's a molecule.
00:54
So definitely there will be the london force, the dispersion interaction.
01:04
And another thing is water has hydrogen, right? it can form hydrogen bond.
01:11
So if you draw the configuration, you will probably have this.
01:18
You have the water, right? there will be hydrogen bonding.
01:37
And the third interaction is the dipole -dipo interaction.
01:43
Because if you look at the water itself, it has dipole moment.
01:48
Here is a negative and here is a positive center...
