Question

Statistical Evaluation of Acid-Base Indicators

Q1 / 10 grams KHC₈H₄O₄, molar mass 204.2 g. Calculate the expected volume of NaOH required for the titrations, assuming the NaOH molarity is 0.10 M.

Q2 / A student performs the experiment using thymol blue as the indicator, six titrations are completed, the volumes of NaOH required to reach the endpoint are: 14.08 mL, 14.10 mL, 13.96 mL, 14.22 mL, 13.94 mL, and 14.06 mL. Use an appropriate statistical test to determine if any of these volumes can be discarded as a questionable piece of data
