Which of the following has the highest molar solubility? Agcl: K_ap = 1.8 Times 10^-19 CaF_2: K_ap = 3.4 Times 10^-11 Bl_2S_3: K_ap = -1.1 Times 10^73 The concentration of calcium ions in a saturated solution of calcium phosphate is equal to 7.42 Times 10^-6 M. K_ap for calcium phosphate is equal to: 5.50 Times 10^-11 1/00 Times 10^-12 1.00 Times 10^-26 2.25 Times 10^-26 9.00 Times 10^-26 K_ap for PbBr_2 is equal to: 4.67 Times 10^-6. How many grams of pbBr_2 will dissolve in 250.0 mL of solution? (The molar mass of pbBr_2 = 367.01 g/mol.) 0.425 g 0.966 g 1.53 g 3.86 g 15.46 g K_ap for BaF_2 is 1.0 Times 10^-6. Suppose that 30.00 mL of a 0.156 M aqueous solution of Ba(NO_3) is initially combined with 45.00 mL of a 4.69 Times 10^-5 M aqueous solution of NAF. Which of the following is true of Q for the ionization of BaF_2? Q = 1.76 Times 10^-4, and BaF_2 will precipitate from the solution Q = 1.76 Times 10^-4, and BaF_2 will NOT precipitate from the solution Q = 3.43 Times 10^-6, and BaF_2 will precipitate from the solution Q = 4.94 Times 10^-7, and BaF_2 will NOT precipitate from the solution Q = 4.94 Times 10^-7, and BaF_2 will precipitate from the solution K_ap for pbl_2 is 6.50 Times 10^-9, NaI is slowly added to 750.0 mL of a 0,350 M aqueous solution of pb(NO_3)_2. How many mol of NaI can be added to this solution before precipitation of pbI_2 begins? (Assume the highly pb(NO_3)_2) is initially completely dissolved in solution.) 1.02 Times 10^-4 mol 1.36 Times 10^-4 mol 1.82 Times 10^-4 mol 1.76 Times 10^-3 mol 2.35 Times 10^-3 mol The radioactive decay of Tc to produce Ru results from emission of a: alpha particle positron beta particle neutron a gamma rayExplanation / Answer
1) b is the answer, since CaF2 has higher Ksp, so maximum amount of CaF2 is dissolved and thus higher molar solubility.
