Chapter 8, Problem 8.95(choose chapter or problem)
Consider 100.0 mL of a solution of 0.200 M Na2A, where A22 is a base with corresponding acids H2A (Ka 5 1.0 3 1023) and HA2 (Ka 5 1.0 3 1028). a. What volume of 1.00 M HCl must be added to this solution to reach pH 5 8.00? b. Calculate the pH at the second stoichiometric point of the titration of 0.200 M Na2A, with 1.00 M HCl.
