pKa and pKb

I know pKa and pKb help us see how acidic or basic compounds are, but do they actually mean?

literally pKa just means the -log of the concentration of the products over the concentration of the reactants

It is the negative log of the Ka value. A lower pka indicates that an acid is stronger because it shows that the acid more fully dissociates.
