We did an experiment to estimate the isoelectric point of Casein by pH/Turbidity Titration.
In the practical we made up solutions of 9ml using different volumes of acid and distilled water. Here are 3 examples; it's been a long time since I've done this and would really appreciate help with the method.
A B C
Distilled Water 8.40 7.75 6.50
0.01M Acetic acid 0.60 1.25 2.50
PKa = 4.76
My initial reaction was to get the Ka via the Pka and then using that to get the [H+] that can then be used to get the pH but that method would give me the same answer for all of them? Any help would be greatly appreciated.

Each prepared sample has a different concentration of acetic acid.
