Its Ksp value is? The answer is 4s^3. Why? I dont understand this at all, even with the AAMC answer given. So one of you experts please help me out...

When M(OH)2 dissociates it does so into one part M and 2 parts OH. Ksp is the product of the concentrations of the dissociated ions to the powers of their stoichiometric coefficients. Ksp = [M] * [OH]^2 = s * (2s)^2 = 4s^3. Upvote 0 Downvote
