enumerate the steps necessary to create a Phosphate Buffer NaH2PO4 - K2HPO4 with a final volume of 500 mL, a concentration of 0.10M, and a pH of 7.20 using 0.20 M NaH2PO4 and solid K2HPO4. Nota bene: Ka equals 6.3 x 10-8. (show computation as well) For solid K2HPO4, calculate for the mass (based from calculated moles of salt) rather than the volume since this is a solid substance.

What among the following statements is false regarding the Henderson-Hasselbalch equation? a. A buffer cannot effectively buffer a system at pH = pKa b. It shows us the relationship of pH and a buffer system, which originally was derived by relating the pH and the carbonate buffer system of the blood c.
