In this problem, you have two compounds, lithium sulfate and cesium sulfate, and you are asked to determine which of the two has the more exothermic heat of hydration.
00:29
It's important to remember that a more exothermic heat of hydration corresponds with the strength of the ion dipole interactions between the dissolved ions and the water.
00:46
Greater ion dipole interactions mean a more exotheric heat of hydrant.
00:54
There are three main factors that affect the strength of the ion dipole interactions.
01:11
There's the distance between the center of the ion and the pull of the dipole, which is impacted by ion size.
01:21
Larger ions have a greater distance to the center.
01:26
Another factor is charge.
01:31
Ions with a greater magnitude of charge experience more ion dipole interactions.
01:37
And finally the magnitude of the dipole.
01:46
However, in terms of heat of hydration, this last factor is pretty irrelevant because the dipole is water in every case.
01:56
So it would be the same...
