What is the concentration of free Ni2+ ions in a saturated Ni(OH)2 solution if the pH is buffered to remain at 8.4? The Ksp of Ni(OH)2 is 6.0 x 10^-16.

Please, help. I'm stuck. I don't know what to do with that pH value. I got 2.1 x 10^-6 but that's just the concentration disregarding that pH value mentioned in the question, right?
