A sample of an ionic compound NaA, where A- is the anion of a
weak acid, was dissolved in enough water to make 100.0 mL of
solution and was then titrated with 0.100 M HCl. After 500.0 mL
of HCl was added, the pH was measured and found to be 5.00.
The experimenter found that 1.00 L of 0.100 M HCl was required
to reach the stoichiometric point of the titration.
a. What is the Kb value for A?
b. Calculate the pH of the solution at the stoichiometric point
of the titration.
