1) Acetate / Acetic Acid Biffers.
A) Starting with a 1.00 L solution that contains 0.25 M Ascorbic Acid and 0.50 M Na Ascorbate. Use the Henderson Hasselbalch Equation to calculate the pH, assuming that the Asborbic Acid Dissociation Constant= 8.0 x 10^-5 ?
B) Use the Henderson Hasselbalch Equation to calculate the pH after the addition of 0.10 M NaOH to this solution, assuming no change in volume?
