Q. A buffer solution prepared by mixing 50.00 mL of 0.200 M acetic acid and 50.00 mL of 0.200 M sodium acetate (Ka, acetic acid = 1.76 x 10-5). (Hint: Calculate the pH using the Henderson-Hasselbach equation, remember to allow for the dilution effect when mixing the two solutions together.)
A buffer solution that is 0.10 M sodium acetate and 0.20 M acetic acid is prepared. Calculate the initial pH of this solution The K, for CH3COOH is 1.8 x 10-5 M. As usual, report pH to 2 decimal places. Answer: A buffered solution resists a change in pH. Calculate the pH when 21.2 mL of 0.031 M HCl is added to 100.0 mL of the above buffer. Answer:
Calculate the pH of a buffer solution prepared by mixing 75 mL of 1.0 M lactic acid and 25 mL of a 1.0M sodium lactate. (pka of lactic acid = 3.86) Calculate the change in pH that occurs when 0.01moles of OH are added to a 1L buffered solution that contains 0.5M acetic acid (HC_2H_3O_2) and 0.5M acetate ion (C_2H_3O_2). Acetic acid pka = 4.76.
