In acid-base reactions, chemists tend to work with Ka, instead of the traditional K. pKa is simply equal to -log Ka. Favorable acid-base reactions have a large value for K and Ka (greater than 1) and a small value for pKa (less than 0). Unfavorable reactions have small values for K and Ka (less than 1) and large values for pKa (greater than 0). pKa is therefore a property of an acid-base reaction that allows one to determine how favorable the reaction is.
