In a biochemistry laboratory, you are asked to prepare a buffer solution to be used as a solvent for isolation of an enzyme. On the shelf are the following solutions, all 1.00 M: formic acid (Ka = 1.8 × 10-4), acetic acid (Ka = 1.8 × 10-5), sodium formate (NaHCO2), and sodium acetate (NaCH3CO2). Describe how you would prepare 1.0 L of a pH = 4.65 buffer solution with total molarity of 0.32 M.
