WebThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton. The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less ... WebThe pKa values for organic acids can be found in Appendix II of Bruice 5thEd. Table of Acids with Ka and pKa Values* CLAS. * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6thEd.
