7. A 25.0 mL solution of 0.0015M BaCl2 is added to 20.0 mLs of 0.0010 M Na2SO4. Determine if the resulting solution will have a precipitate form or if it will remain unsaturated. Ksp (BaSO4) = 1.1.x 10-10
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?
A solution of Na2SO4 is added dropwise to a solution with 0.020 M Ba2+ and 0.020 M Sr2+. (for BaSO4, Ksp = 1.1x10–10 and for SrSO4, Ksp = 3.2x10–7) (a) What precipitate will form first? Why? (b) What concentration of SO4 2– in the solution is necessary to begin precipitation? (neglect any volume change)
Which of the following is the minimum amount of moles of NaOH that must be added to a 1 L solution that contains 4.3 x 10–6 M Cd2+ for the sparingly soluble salt Cd(OH)2 (Ksp = 2.5 x 10–14) to crystallize?
A 40.0-mL solution contains 0.033 M barium chloride (BaCl2). What is the minimum concentration of sodium sulfate (Na2SO4) required in the solution to produce a barium sulfate (BaSO4) precipitate? The solubility product for barium sulfate is Ksp = 1.1 ✕ 10−10.
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?
1 A.What is the Q value when 275.0 mL of 0.020 M BaCl2 and 225 mL of 0.040 M Na2SO4 are mixed together. The Ksp of BaSO4 is 1.5 x 10 –9 Note: Your answer is assumed to be reduced to the highest power possible. 1 B.Will a precipitate form when 275.0 mL of 0.020 M BaCl2 and 225 mL of 0.040 M Na2SO4 are mixed together. The Ksp of BaSO4 is 1.5 x 10 –9 yes or no 1...
A 40.0-ml solution contains 0.021 M barium chloride (BaCl2). What is the minimum concentration of sodium sulfate (Na2SO4) required in the solution to produce a barium sulfate (BaSO4) precipitate? The solubility product for barium sulfate is Ksp = 1.1x10-10 Supporting Materials Periodic Table Supplemental Data Constants and Factors
A solution contains 0.040 M of Na2SO4 and 0.050 M of NaIO3. Another solution of Ba2+ is added to the first solution.( You must accept that the original solution does not include HSO-4). a) Which of the Baryum salts precipitate firstly? b) Calculate the Ba2+ concentration while the first precipitate is occuring. c) While the more dissolved precipitate is precipitating, what is the concentration of anion which forms the less dissolved Baryum salt ? Ba(IO3) Ksp= 1.57x10-9 BaSO4 Ksp= 1.1x10-10
If 100 mL of a .100 mol/L CaCl2(aq) and 100 mL of 0.0400 mol/L Na2SO4(aq) are mixed at 20°C, determine whether a precipitate will form. For CaSO4(aq) at 20°C, Ksp is 3.6 x 10-5.
