In this and following chapter's, more difficult problems are indicated by an asterisk.
(a) Suppose you wanted to make a buffer of exactly pH 7.00 using KH2 PO 4 and Na 2 HPO 4. If the final solution was 0.1 M in KH2 PO 4 , what concentration of Na 2 HPO 4 would you need
(b) Now assume you wish to make a buffer at the same pH, using the same substances, but want the total phosphate molarity ( [HP0 4 -2 ] + [H2 P0 4 ]) to equal 0.3. What concentrations of the KH2 PO 4 and Na 2 HPO 4 would be required
