I have been going over many practice problems for Ksp and solubility, and I am still getting confused.
For example:
There is a passage in BR with a question that says, "The maximum [Ca2+] in a pH=14 solution would be which of the following values?"
They gave a Ksp for Ca(OH)2 at Ksp = 4.3*10^-6 M^3 in the passage
I solved it like this:
Since they gave a pH of 14, I knew the [OH-] was 1 because of 10^-poH
I took that as meaning that the initial concentration of OH- before dissolution of...
