Potentiometeric Titrations
Purpose: The purpose of this lab was to construct a titration curve by titrating Formic acid using a standardized sodium hydroxide (NaOH) and a pH meter through potentiometric titration. After the data for the rest of the class is collected, compare and contrast the equivalence points to see how the concentrations of the various acids affected the acids weakness and strength.
Methods:
Obtain 0.020 M of Formic Acid (HCCOOH). Calibrate the pH meter using the instructions for calibrating the pH meter in the appendix. After the calibration of the pH meter, 150 mL of Formic acid solution was dispensed into a clean dry beaker, and then 50 mL of the formic acid was transferred into a 250mL beaker. After the burette was rinsed twice with a couple of mL of standardized (NaOH) solution, it was filled with approximately 0.62 mL (NaOH)(start anywhere between 0.1 to 1ml). The pH meter...
