CHEM 14BL Chapter Notes - Chapter 4: Titration Curve, Titration, Volumetric Flask
Document Summary
Purpose: understand the various graphical methods to determine the equivalence point and. Look at the vertical portion of the titration curve. The center of the vertical portion of the titration curve corresponds to the equivalence point. Allows better preicision, in determining the equivalence point. The first derivation titration curve is the slope ( rise over run ) of the titration curve. Draw lines on first derivative graph that best fit the points. The intersection of the lines correspond to the equivalence point. (see example above) No, the highest data point is not necessarily the equivalence point. Example: a student recorded the concentration of the naoh stock solution, (2. 034 0. 001) m. the student pipetted. 10. 00 ml of the naoh stock solution into a 100. 00 ml volumetric flask. The student diluted to the mark with distilled water. Then, vinegar was placed in a beaker with a 5. 00 ml pipet.
