If the concentration of calcium ions in solution at equilibrium is 1.0 x 10°M, what is the Ksp of calcium phosphate? a. 4.4 x 10-46 b. 2.2 x 10-46 c. 1.1 x 10-46 d.5.5 x 10-47 a. b. O C. d. KESCION 20 5 pts 14a) Sodium chromate is added to a solution of 0.0060 M 5r2+ What is Q if the final concentration of Cro 2 is 0.0030 M? a. 7.2...
2. If two solutions of equal volume, one saturated with CrPO. (Ksp = 2.4 x 10-4) and the other saturated with Ca(103)2 (K. = 1.0 x 10-) are mixed, will Cas(PO4)2 precipitate? The K. of Cas(PO4)2 is 1.3 x 10-32 You may assume that each solution contains no undissolved solids prior to mixing: {7 marks) Hint: Don't forget that when the two solutions are mixed, their volumes are combined!
1. Will a precipitate form if 200.0 mL 0.00020M Ca(NO3)2 is mixed 300.0 mL of 0.00030M Na2CO3? Ksp= 5.0 x 109 2. Will a precipitate form if 25.0 mL of .0020M Pb(NO3)2 is mixed with 25.0 mL of 0.040M NaBr. Ksp = 6.6 x 106 3. Will a precipitate form if equal volumes of 0.00020M Mn(NO3)2 is mixed with 0.00030M Na2PO4? Ksp = 1.0 x 1022
Question 1 1 pts The Ksp value for BaSO4 Ksp = 1.1 x 10 10. If 50.0 mL of 2.0 x 10-4 M Ba(NO3)2 is mixed with 350.0 mL of 1.0 x 10-5 M Na2SO4, will a precipitate be observed? A precipitate forms because the ion pair product, Q> Ksp A precipitate forms because the ion pair product, Q< Ksp. No precipitate forms because the ion pair product, Q = Ksp No precipitate forms because the ion pair product, Q<Ksp...
Will a precipitate form when 100.0 mL of 6.8 x 10-4 M Mg(NO3)2 is added to 100.0 mL of 1.2 x 10-4 M NaOH? The ion product for Mg(OH)2 is 1. Since Q is than Ksp, Mg(OH)2 precipitate from the solution.
What is Qsp and will a precipitate form when 100.0 mL of 1.00 x 10-4 M Pb(NO3)2 is mixed with 50.0 mL of 5.00 x 10-4 M Li2SO4? Ksp = 2.13 x 10-8 7.43 x 10-13, no precipitate 5.00 x 10-10, precipitation 1.11 x 10-8, precipitation None of the choices is correct. 2.50 x 10-10, no precipitate
If I dissolve 1.0 x 10-4 mole of Mg(NO3)2 and 1.0 x 10- 4 mole of Na2CO3 in one liter of water, will I obtain a precipitate. Ksp for MgCO3 = 3.5 x 10-8. 1 Yes NO N
