So for this problem, consider nacl.
00:03
Nacl in water will form na plus and cl minus.
00:08
And we assume that once it's in solution, these are completely separate ions.
00:15
And so, you know, they both play their own role in, you know, freezing point depression, boiling point elevation, anything that really, you know, are our collative properties that result in a van hoff factor.
00:28
And so we assume for every one mall.
00:30
Molecule of nacl we got out, we're getting two completely separate molecules.
00:36
But in reality, you know, there's a bunch of these swimming around in the water.
00:40
And so there's still an electrostatic attraction between them...
