Phosphoric acid H3PO4 is a triprotic acid with pKa values of 2 12 7 21 and 12 32 It is a useful buffer solution for pH values near the pKa values You have a 0 100 M solution of phosphate buffer with a pH of 2 50 How many mL of 0 500 M NaOH solution must be added to 1 00 L of this buffer solution to convert it to a buffer at pH 7 70
