Question

Silver hydroxide will be least soluble in a solution with pH of a)3 b)5c)7d)9e)11?

Answer 1

it should be at whatever pH has the greatest [OH-], & that would make it a pH 11

the only problem is I can't find a K for [Ag(OH)2]-,

it exists,

& if it forms , it would dissociate some of your ppt.

I hope it does form in lieu of AgOH ( k = 1.5e-8), at that high pH of 11
