The Ka for a weak acid, HA, is 1.6x10-6. What are the (a) pH and (b) degree of ionization of the acid in a 10-3 M solution? (c) Calculate pKa and pKb

Answer 1

Why don't you scroll down and read some of the chemistry (this one was under biochemistry). I have worked this one before. The url is here.
