A 100.0 mL sample of 0.20 M HF is titrated with 0.10 M KOH. Determine the pH of the solution after the addition of 400.0 mL of KOH. The K_a of HF is 3.5 times 10^-4. 13.08 12.60 13.85 12.30 12.78 A 100.0 mL sample of 0.10 M Ca(OH)_2 is titrated with 0.10 M HBr. Determine the pH of the solution after the addition of 300.0 mL HBr. 1.60 1.30 1.00 12.40 1.12 When titrating a strong monoprotic acid and KOH at 25 degree C, the pH will be less than 7 at the equivalence point. pH will be greater than 7 at the equivalence point. titration will require more moles of base than acid to reach the equivalence point. pH will be equal to 7 at the equivalence point. titration will require more moles of acid than base to reach the equivalence point.
