scienceattech.combuffer region EQUIVALENCE POINT phenolphthalein color change The total volume is 25.15 mL, and both the acid and conuugate base (acetate) are present at the same concentration. We have a BUFFER. At the halfway point, the pH = pKa of the acid! Find the pH of this buffer using the Henderson-Hasselbalch equation. Useful for finding acid ionization ...
