The synthesis of the serum requires a reaction solution with precise control of the pH. Your responsibility for the project is to develop a buffer that maintains the pH at 6.80, the optimal level for the synthesis. In a thorough, wise, and careful essay, discuss how you will design and prepare 1.0 L of pH = 6.80 buffer to test the synthetic method. You will need to choose a specific acid-conjugate base pair and reasonable concentrations of other reagents needed (0.0100 M to 1.0 M). Also, briefly discuss the limitations of your buffer system.
