as 5.62 x 10 -8 . The difference between the K a1 values is -1.9 x 10 -3 and the difference between the K a2 values is -5.8 x 10 -9 . The percent error for my K a1 value is -25 % and the percent error for my K a2 value is -9.4 %. However, when you compare the pH values that you derive the K a values from the margin of difference doesn’t look quite as large. The pH for the K a1 listed in the book would be 2.1 and the pH for my K a1 would be 2.25, only accounting for a 5.9 % error. The pH for the K a2 listed in the book would be 7.2 and the pH for my K a2 would be 7.25, only accounting for a 0.59 % error. 4.How could you check that the decarbonation process was sufficient (i.e., did not affect your titration results) for the cola soft drink that you titrated?

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
