A 120.0-mL aliquot of 0.114 M weak base B (pKb = 4.58) was titrated with 1.14 M HClO4. Find the pH at the following volumes of acid added: Va = 0.00, 1.30, 6.00, 11.00, 11.90, 12.00, 12.10, and 17.00 mL. (Assume Kw = 1.01 ✕ 10−14.)
Question 2 15 P Weak Acid Titration Calculations. A 25.0 mL aliquot of 0.50 M propanoic acid (CH3CH2O2H) is placed in a 250 mL Erlenmeyer flask and titrated with a standardized solution of 0.25 M NaOH. The pKof propanoic acid is 4.88. Calculate the pH of the solution after the addition of the following volumes of acid. Neglect activity. (15 points) a) 0.00 mL of NaOH added: 2.59 b) 50.00 mL of NaOH added: 8.49 c) 75.00 mL of NaOH...
