A solution of a weak monoprotic acid requires 39.28 mL of 0.01712 M NaOH to reach the equivalence point. After addition of 17.19 mL of titrant, the pH = 3.33. What is the pKa of this acid? Express your answer with two decimal places.
If the pH at the equivalence point for titration of a monoprotic weak acid with NaOH is 9.00, and 10 mL of base is required to reach the equivalence point, how would you determine the pKa of the acid? the pKa is 9.00 determine the pH after 5 mL of base is added; this is the pKa determine the pH when 20 mL of base is added; this is the pKa the pKa is -log(9)
