Which of the following pairs of solids has the smaller molar solubility? a. CaF2 or BaF2 b. Cas(PO4)2 or FePO4 c. FeC2O4 or Cu(104) d. Ag Co; or Mn(OH)2 3. Calculate solubility of the following solids in the given solution. a. Fe(OH), in (a) water; 6) pH = 5.0 buffered solution; (c) pH - 11.0 buffered solution b. Ag.SO in (a) water; (b) 0.10 M AgNO3; (e) 0.20 M K SO: 4. Will a precipitate form when a. 75.0 mL of 0.020 M BaCl2 and 125 mL of 0.040 M Na2SO4 are mixed together? b. 100.0 mL of 4.0 x 10* M Mg(NO3)2 is added to 100.0 mL of 2.0 x 104 M NaOH? 5. Given the following data Mn?" (aq) + CO2(aq) = MnC_04(aq) K-7.9 x 10 MnC_0:(aq) + C_042 (aq) = Mn(C_0.) K = 7.9 x 101 calculate the value for the overall formation constant for Mn(C0.)? 6. Solutions of sodium thiosulfate are used to dissolve unexposed AgBr in the developing process for black-and-white film. What mass of AgBr can dissolve in 1.00 L of 0.500 M Na2S 0:? Ag* reacts with S:0,2 to form a complex ion: Ag" (aq) + 2 S 03 (aq) = Ag(s.Os), "(aq) K=2.9 x 101
