Consider the titration of 100.0 mL of 0.42 M H3A by0.42 M KOH for the next three questions. The triprotic acid hasKa1 = 1.0 x 10-4, Ka2 = 1.0 x10-7, and an unknown value for Ka3. Allanswers to 3 significant digits.

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

pH =

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

pH =

3) The pH of the solution after 200.0 mL of KOH has been addedis 9.00. Determine the value of Ka3 for this triproticacid. Use scientific notation to enter this answer, e.g., 1.0 x10-3 = 1.0E-3.

Ka3 =
