Question

Where can I find a table over pKa values that I can use for academic reference?

Answer 1

Are you looking for a specific type of chemistry (ie: Organic, gen chem)?

Answer 2

most college-level chemistry textbooks have pKa values in an appendix in the back of the book. Usually these tables mention only weak acid\weak base values. You could also try a reference like the CRC handbook or the Merck index.
