Applications of Aqueous Equilibria

50.00 mL of a 1.00 M solution of the diprotic acid H2A (Ka1= 1.0 * 10^-6 and Ka2 = 1.0 * 10^-10) is being titrated with 2.00 M NaOH . How many mL of 2.00 M NaOH must be added to reach a pH of 10?

Solution Preview

These are tough questions, you will have to treat it as a buffer, but since it also features a diprotic acid, you have to decide which conjugate acid base pair with which to construct your buffer. This decision will be based on the pH desired (pH = 10).

Using the combination of HA- <--> A-2 coupling and making a buffer out ...
