I am weak on the algebra of the Henderson-Hasselbach equation.(adsbygoogle = window.adsbygoogle || []).push({});

I have a prelab question:

Using the H-H equation, calculate the volumes of 0.1 MM phosphate solutions to mix to prepare 100ml each of buffers with pH values 6.0, 6.5, 7.0,7.5, and 8.0 starting with 01.M stock solutions of NaH2HPO4 and Na2HPO. The relevant reaction is given below:

H2PO4- -->HPO4^2- + H+

The pKa is 7.21.

I know the pH is the values listed.

pH=pKa+log{[A-]/[HA]}

How do I start this problem?
