3) Consider the pH of metal hydroxides in water. a) Estimate the pH of a solution of saturated Ba(OH)2. Ksp = 5.0 x 10 -³. b) Consider the concentration of hydroxide in pure water (think about the actual concentration of hydroxide as a molarity). Write that concentration here. c) If the concentration of hydroxide directly from a metal hydroxide dissolving in water is much much less than the concentration of hydroxide in pure water, can the metal hydroxide dissolving in water actually change the pH? These two parts of this question is mean to help you think about the next part of the question and help you have productive conversation! d) Estimate the pH of a solution of saturated Co(OH)3. Ksp = 2.5 x 10 - 4³.
