A solution of Na2SO4 is added dropwise to a solution that is 1.1×10−2 M in Ba2+ and 1.1×10−2 M in Sr2+. 1. What concentration of SO2−4 is necessary to begin precipitation? (Neglect volume changes. BaSO4:Ksp=1.1×10−10; SrSO4:Ksp=3.2×10−7.) 2. What is the concentration of SO2−4 when the second cation begins to precipitate?
how much Sr2+ will precipitate if 10^-3 mole Na2SO4 added per litter of solution. How much SO42- and Sr2+ remain after precipitation. Given that 10-4 mole/L of Sr2+ and 10-4 of SO42- are originally present and that pKso = 7.8 for SrSO4 (s)
A solution of Na2SO4 is added dropwise to a solution that is 1.1×10−2 M in Ba2+ and 1.1×10−2 M in Sr2+. The solubility-product constants are as follows: BaSO4:SrSO4:KspKsp==1.1×10−103.2×10−7 You may want to reference(Pages 751 - 753) Section 17.6 while completing this problem. Which cation will precipitate first? Ba2+ precipitates first. Sr2+ precipitates first. What concentration of SO42− is necessary to begin precipitation? (Neglect volume changes.)

Question 6 0 / 1.5 pts To 0.500 L 1.00 x 10-MAgNO3 solution, 5.0 x 10-6 mole of NaCl solid is added. Ksp for AgCl is 1.6 x 10-10. What is Asp of AgCl? Will AgCl form precipitate? 5.0 x 10-11, no precipitate
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?
Solid sodium sulfate, Na2SO4, is added slowly to a solution that is 1.0 x 10-4 in both Ba2+ and Pb2+ until [SO42-] reaches 1.0 x 10^-4 M. Would either BaSO4 (Ksp = 1.1 x 10^-10) or PbSO4 (Ksp = 1.7 x 10^-8) precipitate under these conditions?
Questions: 1. Calculate the Ksp for PbBr2 if its molar solubility is 2.14 x 10-2 M at 25°C. 2. Calculate the molar solubility of CaF2 (Ksp = 4.0 x 10-11) in a 0.025 M NaF solution. 3. Solid sodium sulfate, Na2SO4, is added slowly to a solution that is 1.0 x 10-4 in both Ba2+ and Pb2+ until [SO42-] reaches 1.0 x 10-4 M. Would either BaSO4 (Ksp = 1.1 x 10-10) or PbSO4 (Kop -1.7 x 10-8) precipitate under...
