Re: pKa values
I'm not sure if there is an index of these values. They should be given to you by problem or the problem may tell you to look at a table to find the pKa or Ka values. Also if you are given the Ka you know the pKa and vice versa.

Re: pKa values
A table will be given in the book. Sometimes though it will give us the K value for the conjugate base/acid, so we would need to manipulate Kw=Ka*Kb.

Re: pKa values
Tables 12.1 and 12.2 in the textbook (6th edition) list the pKa and Ka for common acids and the pKb and Kb of common bases. In addition, many problems will give you either the pKa, Ka, pKb, and Kb which you can then use to figure out the other three values, using
1.00 x 10^-14 = Kw = Ka x Kb, pKa = -logKa, and pKb = -logKb.
1.00 x 10^-14 = Kw = Ka x Kb, pKa = -logKa, and pKb = -logKb.
