To make a phosphate buffer at pH 9.6 starting with 1L of 10 mM phosphoric acid (H3PO4; pKs are of 2.15, 6.82, and 12.38 determine how much KOH ), you could add?
Based on your understanding of the relationship between acid/base behavior and chemical structure, match the Ka with each acid. Then calculate the pKa which corresponds to each value.
