a. What combination of a molecular base (that is a neutral compound, not an ion!) and a salt of the conjugate acid of that molecular base should you select to prepare a buffer solution that would maintain a pH of 9.00? For full credit, explain your choice (in a simple, straightforward manner, keep your answer under 40 words and don't forget to specify a common spectator ion as the counter-ion in the salt).
b. What ratio of concentrations of the molecular base you chose in part a and its conjugate acid would be necessary to achieve a pH of exactly 9.00?
c. Describe, using one well-written sentence, a simple and practical way to make 1.00L of this buffer solution, assuming a 1.0 M solution of the molecular base is available and that the chloride salt of the conjugate acid is available as a solid. (Note: Laboratory balances are calibrated in grams and pipettes in mL, neither are calibrated in moles
