We can only compare ksp values directly to estimate relative solubilities if the ions produce, if the compounds produce the same number of ions.
00:12
So in the case of compound 1, magnesium hydroxide, that generates three ions, two hydroxides and one magnesium.
00:25
In the case of compound 2, lead sulfate, they didn't tell us whether it was lead 4 or lead 2, so i'll assume the more common lead 2 sulfate, that produces two ions, one lead 2 plus and one sulfate.
00:41
So we could compare ksp's directly for magnesium hydroxide with silver sulfite, that generates three ions, and silver carbonate, that also generates three ions.
01:08
But in the case of lead 2 sulfate, we could compare it with manganese carbonate, producing two ions, and silver hydroxide, also producing two ions.
01:26
Then for the second question, because manganese hydroxide creates, or magnesium hydroxide creates three ions, then the ksp expression is going to be mgoh2 going to mg2 plus, plus two hydroxides...
