An aqueous solution has 0.0026M Ca(NO3)2 (aq) and 0.0016M KSO4 (aq). Ksp [CaSO4] = 2.4 × 10-5 Ksp [CaC2O4] = 2.3 × 10-9 What describes the system best? Q > Ksp and no precipitate forms Q < Ksp and a precipitate forms Q < Ksp and no precipitate forms Q > Ksp and a precipitate forms Q = Ksp and the solution is saturated
The Ksp of Ca(OH)2 is 6.5 x 10-6. Will a precipitate form if the pH of a 0.085 M CaCl2 solution is adjusted to 8.8?
2. A solution is 0.01 M in Ba2+ and 0.01 M in Cal. Sodium sulfate is added to selectively precipitate one of the cations, while leaving the other in solution. a) Given that BaSO4 and CaSO4 have kse values of 1.07 x 10-10 and 7.10 x 105 respectively, which cation will precipitate first? Explain why. b) What is the minimum concentration of S0,2" that will trigger the precipitation of the cation that precipitates first?
A solution is 0.0045 M in both Pb2+ and Ca2+. Solid Na2SO4 is added to precipitate the sulfates. What concentration of SO42‒ is needed to precipitate as much of the Pb2+ without precipitating the Ca2+? Ksp(PbSO4) = 1.6 × 10‒8, Ksp(CaSO4) = 2.4 × 10‒4
Will Ca(OH)2 precipitate from solution if the pH of a 3.0×10−2 M solution of CaCl2 is adjusted to 8.0? Will Ag2SO4 precipitate when 100 mL of 4.0×10−2 M AgNO3 is mixed with 10 mL of 5.0×10−2MNa2SO4 solution?
A saturated solution of CaSO4 is made by dissolving excess solid CaSO4 in a 1 L solution of 0.077 M Na2S04. When the solid CaSO4 is added to the solution only 43. 3 mg of the solid actually dissolves. Find the Ksp for CaSO4.
