E. Reflection 1.Did you see the expected number of equivalence points for a triprotic acid? Why or why not? 2. How did the concentration of H 3 PO 4 determined from each of the equivalence points compare? Explain any difference or similarity. The two equivalence point concentrations for the H 3 PO 4 solution titration were fairly close. The first equivalence point concentration was 0.043 M and the second equivalence point concentration was 0.053 M. This is a difference of 0.010 M, a percent error of 23 % when going from 0.043 to 0.053, and a percent error of -19 % when going from 0.053 to 0.043. The equivalence point concentrations for the H 3 PO 4 in the soft drink titration of SodaStream Dr. Pete differed quite a bit more than those of the H 3 PO 4 solution. The first equivalence point concentration was 0.00288 M and the second equivalence point concentration was 0.00575 M. This is a difference of 0.00287 M, a percent error of 99.7 % when going from 0.00288 to 0.00575, and a percent error of -49.9 % when going from 0.00575 to 0.00288. 3. How did the K a values match those listed in your textbook? Explain any difference or similarity. The K a values listed in my textbook are fairly similar to the K a values that I obtained in my experiment. The book lists K a1 as 7.5 x 10 -3 and K a2 as 6.2 x 10 -8 . I obtained the values of K a1 as 5.62 x 10 -3 and K a2 as 5.62 x 10
