Here we're asked of a number of statements.
00:03
We're asked to determine whether they're true or false.
00:06
Part a says, the higher the temperature, the more soluble most gases are in water.
00:10
This is false.
00:12
For gases, as temperature, for gases, this is specific.
00:20
As temperature increases, solubility decreases.
00:29
So if we're at a higher temperature, we expect gases to become less soluble.
00:35
So this is false.
00:38
But for ionic solids, the opposite is true.
00:42
For ionic solids, as temperature goes up, solubility increases.
00:47
For most ionic solids, there is maybe one or two exceptions.
00:52
But in general, as we increase the temperature, we're better able to dissolve ionic solids soon water.
00:58
Which leads us to part c.
00:59
As you cool, they saturate a solution from high temperature, low temperature, solids start to crystallize out of solution if you achieve a super saturated solution...
