The precipitation of Al(OH)3 (Ksp = 1.3 × 10-33) is sometimes used to purify water. (a) Estimate the pH at which precipitation of Al(OH)3 will begin if 5.0 lb of Al2(SO4)3 is added to 2000 gal of water. (b) Approximately how many pounds of CaO must be added to the water to achieve this pH?
ustion1-At 25 oC the solubility of lead(II) chloride is 1.59 x 10-2 mol/L. Calculate the value of Ksp at this temperature.?
qustion2-The Ksp of Al(OH)3 is 1.0 x 10-33. What is the solubility of Al(OH)3 in 0.0010 M NaOH?
qustion3-The Ksp of Al(OH)3 at 25 oC is 1 x 10-33. Consider a solution that is 2.0 x 10-10 M
At what pH will precipitation of Al(OH)3 (Ksp = 1.3 x 10-33) begin if 6.90 lb of aluminum sulfate, Al2(SO4)3, is added to 1550 gallons of water (with a negligible change in volume)?
