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.
