The ideal vonthoff factor corresponds to the number of ions that the compound separates into.
00:08
So for the case of methanol ch3oh, it's not an ionic compound, so its vonthoff factor is just 1.
00:18
For c6h12o6, it's also not an ionic compound, so one species makes one solute.
00:28
But mgf2 is an ionic compound, and one of these makes three ions.
00:37
Kbr, one makes two ions, one potassium, one bromide.
00:45
Scno3, three, makes four ions, two nitrates, and one scandium.
00:58
Na3po4 separates into three sodiums and one phosphate.
01:03
That's a vonthoff factor of four.
01:05
Potassium sulfate separates into two potassiums and one sulfate...
