The ph of the solution after 2000 ml of koh has been added


Consider the titration of 100.0 mL of 0.59 M H3A by 0.59 M KOH for the next three questions. The triprotic acid has Ka1 = 1.0 x 10-3, Ka2 = 1.0 x 10-6, and an unknown value for Ka3.

1) Calculate the pH after 100.0 mL of KOH has been added.

2) Calculate the pH after 150.0 mL of KOH has been added.

3) The pH of the solution after 200.0 mL of KOH has been added is 8.00. Determine the value of Ka3 for this triprotic acid. Use scientific notation to enter this answer, e.g., 1.0 x 10-3 = 1.0E-3.
