How many moles of lead (II) fluoride, PbF2, can be dissolved in 31.5 L of water? PbF2 (s) -- Pb2+ (aq) + 2F (aq) (Ksp = 3.6x10-8) O A. 0.019 mol OB. 0.066 mol OC.2.1 x 10-3 mol OD. 0.083 mol
What is the pH of a 3.5 x 10-4 M solution of calcium hydroxide? How many moles of lead (II) fluoride, PbF2, can be dissolved in 31.5 L of water? PbF2 (s) ↔ Pb2+ (aq) + 2F¯ (aq) (Ksp = 3.6x10−8 )
Lead (II) fluoride, PbF2, crystallizes in a cubic unit cell in which the lead ions occupy a face-centered cubic arrangement in the unit cell, and the fluoride ions are located in certain spaces between the lead ions. How many of each ion are contained within a single unit cell? # of Pb2+ ions = ? # of F– ions =?
A saturated solution of lead (II) iodide, PbI2 has an iodide concentration of 3.0 × 10-3 mol/ L. Calculate the solubility constant, Ksp, for lead (II) iodide. PbI2 (s) ß---à Pb2+(aq) + 2I-(aq) A saturated solution of lead (II) iodide, Pbl2 has an iodide concentration of 3.0 x 10-3 mol/ L. Calculate the solubility constant, Ksp, for lead (II) iodide Pbl2 (s) 8 3.5 x 10-8 5.0 x 10-8 2.8 x 10-8 1.4 x 10-8 -à Pb2 (aq)+2I(aq)
Learning Goal: To learn how to calculate the solubility from Kspand vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution: CaF2(s)⇌Ca2+(aq)+2F−(aq) At equilibrium, the ion concentrations remain constant because the rate of dissolution of solid CaF2 equals the rate of the ion crystallization. The equilibrium constant for the dissolution reaction is Ksp=[Ca2+][F−]2 Ksp is called the solubility product and can be determined experimentally by measuring thesolubility, which is the amount...

1. If 1.70 x 10-4 moles of Agt(aq) dissolves per liter of water when AglO3 is dissolved, what is the Ksp for AgIO3 ? 2. If you have a solution of Cat2 that has a concentration of 0.050 M, and you adjust the pH of the solution to 8.00, will Ca(OH)2 precipitate. (Ksp for Ca(OH)2 = 6.5 x 106) 3. Determine the concentration of fluoride ion in a saturated solution of PbF2 (in moles/liter), if the Ksp = 3.6 x...
