Calculate the expected pH values of the buffer systems from the experiments (a,b,c,d), using the Henderson-Hasselbalch equation shown in the Background section. Use for pKa values: carbonic acid = 6.37 and acetic acid = 4.75. Experiment A 5 mL .1 M acetic acid + 5 mL .1 M sodium acetate Experiment B 1 mL .1 M acetic acid + 10 mL .1 M sodium acetate Experiment C 5 mL .1 M carbonic acid + 5 mL .1 M sodium bicarbonate Experiment D 1 mL .1 M carbonic acid + 5 mL .1 M sodium bicarbonate

.10 M carbonic acid + c5 mL .20 M sodium acetic acid add to co sign 100 to 4 parts carbonic
acid ....
this should take you to zero just like wonderer said. thumb up for wonderer. mafiata, i certainly hope you are not taking this class. i would appreciate an answer back.
