A 32.44 mL sample of 0.202 M acetic acid is titrated with 0.185 M sodium hydroxide. Calculate the pH of the solution for each the following. You will need to look up values for ionization constants. Using your answers for 1-5, sketch the titration curve. Be sure to label axes, midpoint, and equivalence point, and to identify each of the five data points on the curve. before any NaOH is added. at the midpoint after 24.00 mL of NaOH is added. at the equivalence...
a) Use this plot to estimate the volume of NaOH required to reach the equivalence point of each titration curve. b) Estimate the original concentration of weak acid in solution before strong base was added. c) Find the midpoint pH for each of the trials using half the volume of NaOH required to reach the equivalence point for that trial. Check if this pH is at the most flat part of the titration curve. This is the pKa of the...
