What is the molar solubility of CuS (Ksp = 8.0 x 10-³7) in 0.500 M NH3? (Kf of Cu(NH3)4²* is 5.6 x 10¹¹)

The solutbility constant for Ce(IO3)3 is 3.2x10^-10. What is the Ce3+ concentration in a solution prepared by mixing 50 mL of 0.0450 M Ce3+ with 50 mL of: A.) 0.0450 M IO3- ? B.) 0.0500 M IO3- ?

The solubility of Ag2CrO4 (Ksp = 1.2 x 10-12) is several times greater than that of AgCl (Ksp = 1.82 x 10-10), so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution. If a student uses 1 mg of K2CrO4 Aas an indicator for 100 mL of sample solution, what is the concnetrion of chloride ion in the solution when the red precipitate (Ag2CrO4) starts to form?

A 200.00 mL solution of 0.00105 M AB4 is added to a 270.00 mL solution of 0.00245 M CD5. What is pQsp for AD4? pQsp = -log(Qsp)

6) The KSP of lead (II) iodide, PbI2, is 9.8x10-9. What is the lowest concentration of Pb2+ solution needed toprecipitate with a 0.032 M solution of iodide ions?

Which of the following statements regarding complexometric titrations is ? incorrect The larger the formation O constant for the EDTA- metal complex, the sharper the endpoint EDTA is a tetraprotic acid O The higher the ammonia O concentration, the less sharper the end point for the EDTA-Zn²+ complex In the pH range 3-10 the predominant species is y4- ɑ4 value is proportional to O the pH value

If a solution of 0.15 M Mn² and 0.15 M Cd is gradually made basic, what will the concentration of Cd be when Mn(OH)₂ just begins to precipitate? Assume no change in the volume of the solution For Mn(OH)₂K-1.6 10¹ and for Ca(OH) K-7.2 1015, thus, Mn(OH)₂ is more soluble than Cd(OH)₂ |d³-|- BOSC M
