4. The slightly soluble salt AB2 ionizes as shown. (1) AB, (s) = A²* (aq.) + 2B° (aq.) When a solution of CX is titrated into a saturated solution of AB, the equivalence point is reached when B is completely consumed by the added C²* ion. C2* (aq.) + 2B° (aq.) → CB, (aq.) (2) It takes 5.00 mL of 0.10 M CX solution to reach the equivalence point when titrated into a 20.0 mL saturated AB, solution. Refer to the Introduction and Data Sheet to solve the following problems: a) Refer to equation 1 above and write the Kp expression for AB2 in terms of the ion concentrations and in terms of the molar solubility, s. b) Calculate how many moles of C2* were titrated to reach the equivalence point. c) Based on your result to part b, calculate the number of moles of B in the saturated AB, solution. Consider the stoichiometry of equation 2.

4. The slightly soluble salt AB2 ionizes as shown. (1) АB> (s) — А** (аq.) + 2B (аq.) When a solution of CX is titrated into a saturated solution of AB, the equivalence point is reached when B is completely consumed by the added C²* ion. с* (ад.) + 2B (аq.) — СВ, (аq.) (2) It takes 5.00 mL of 0.10 M CX solution to reach the equivalence point when titrated into a 20.0 mL saturated AB, solution. Refer to the Introduction and Data Sheet to solve the following problems: a) Refer to equation 1 above and write the Kp expression for AB, in terms of the ion concentrations and in terms of the molar solubility, s. b) Calculate how many moles of C2* were titrated to reach the equivalence point. c) Based on your result to part b, calculate the number of moles of B' in the saturated AB, solution. Consider the stoichiometry of equation 2. d) Based on your result to part c, calculate the number of moles of AB, in the saturated solution.
