Create a buffer solution with a pH of 6.0. Based on the assigned pH, you will choose an appropriate buffer system.

pH = pKa + log[A-}/[HA]

A) 3.5M acetic acid 60.1MM, sodium acetate, anhydrous 82.0MM, pKa 4.74 OR

B) sodium phosphate, monobasic, NaH2PO4*H2O 138.0MM, sodium phosphate, dibasic, Na2HPO4 142.0MM, pKa 6.86

Calculate the amount of weak acid and conjugate base you need to make 25mL of 0.25M solutions (one acid and one base solution).
