In order to find out if something is more soluble in water than something else, then we simply need to compare their ksp values if they produce an equal number of ions upon dissociation in water.
00:15
So the bigger the ksp than the more soluble.
00:35
Okay.
00:36
So all we're looking at is for bigger ksps and that will help us figure out.
00:42
If the compound is more soluble.
00:45
So if we take a look at letter a here, barium sulfate, we're comparing barium sulfate versus calcium sulfate.
00:54
So the ksp value of barium sulfate, and they both produce an equal number of ions upon dissociation in water.
01:06
So we can compare the ksp values directly.
01:11
So for the ksp values, value for this is 1 .1 times 10 to the negative 10th and calcium sulfate its ksp value is 2 .4 times 10 to the negative fifth so that means that this one is greater the calcium sulfate has a greater ksp value so this one is more soluble okay now we move on to b here and the they both produce the same number of ions upon dissociation in water...
