The ratio of titrant volume to soda volume was calculated for all trials. Then a Q-test was performed at the 95% confidence level on the data point that was farthest from its closest neighbor. The equation that was used is Q=difference/range. The volume of NaOH used to reach the endpoint for each of the trials was calculated by subtracting the initial volume of solution in the buret from the final volume. The volume of NaOH and the known molarity of the NaOH was then used in the calculations to find the moles of NaOH used for each trial. The equation that was used was molarity NaOH equals moles NaOH divided by volume NaOH in liters. The stoichiometry of the reaction of citric acid with NaOH was used to determine the moles of citric acid for
