After each addition of base, allow the pH reading to stabilize, and record the pH and the volume from the buret on the data sheet. As the titration approaches the equivalence point the pH will begin to increase more rapidly. Once you observe this reduce the volume of the NaOH additions to 0.5mL then 0.2mL until you reach a pH of about 8 to 9. ................
