Describe the process by which adding potassium hydroxide to a saturated aluminum hydroxide solution reduces the concentration of aluminum ions. Write the solubility equilibrium equation and solubility product constant expression for a saturated aqueous solution of aluminum hydroxide.
You need this equation.
Al^+3 + 3OH^- ==> Al(OH)3(s)
Al(OH)3(s) + OH^- ==> Al(OH)4^-
Adding more KOH shifts the equilibrium of both equations to the right.
