Potentiometric titration of base salts

POTENTIOMETRIC TITRATION OF LIDOCAINE HYDROCHLORIDE


By entering the experimental values into a plotting software, the following curve is obtained:
 
Screenshot of a tracing software, with in ordinate a scale from -300 to 200 E/mV, and in abscissa values from 0 to 9 V/mL, the curve being decreasing
The titration curve gives a volume of 5.275 mL NaOH at equivalence
