Consider the titration of 100.0 mL of 0.016 M HOCl (Ka=3.5×10−8) with 0.0400 M NaOH.

Part A
How many milliliters of 0.0400 M NaOH are required to reach the equivalence point?

Part B
Calculate the pH after the addition of 10.0 mL of 0.0400 M NaOH.

Part C
Calculate the pH halfway to the equivalence point .

Part D
Calculate the pH at the equivalence point.
