molarity of the citric acid in a Jones Green Apple soda solution, while the Traditional Method Titration was done to find the molarity in 7 Up. The data in figure 2, table 1 shows that the range of fluctuation in the molarity of the citric acid in the three trials was only 0.08 while performing a Modern titration. However, the range of fluctuation for the molarity of acid in the traditional titration was 1.33 as shown in figure 1, table 1.This shows that the modern titration is almost 17 times more accurate than the traditional. The data also shows that Jones Green Apple has a higher molarity than 7 Up because the standard deviation of the traditional titration (figure 1, table 2) is larger than that of the modern titration (figure 2, table 2).
