A common buffer used in biochemistry is a pH 7.4 phosphate buffer. Such a buffer costs $53.00 for 100.00 mL from a common chemical supply house. Therefore, it is useful to know how to prepare such a buffer yourself! Imagine that you have available 0.1 M KH2PO4 and solid K2HPO4. Describe in detail how you would prepare 100.00 mL of a pH 7.4 phosphate buffer using these two reagents. **Hint: You need to identify what is your acid and what...
