Unformatted text preview: closest acid of the 4 total is Glutaric acid, with a molecular weight of 132.13 grams/mole. The Ka value obtained, 5.62 x 10-5 Ka value, was found by obtaining the pKa value. The pKa value obtained, 4.25 pKa value was set equal to the negative log of the Ka value, and that was how it was found. The accuracy of the Ka value is important because it requires an accurate pKa value. The Ka value found, 5.62 x 10-5 Ka value, directly matches the Glutamic acid, which in the lab notebook, is 5.6 x 10-5 Ka value. The molecular weight in the experiment of the A1 acid, is slightly off from the value of the Glutamic acid, 147.13 grams/mole. The value obtained is 156.47 grams/mole, which is somewhat accurate....
