Preparation of 40 mL of an acetate buffer (pH 4.2) 0.2 M acetic acid (pKa = 4.8) and 0.2 M sodium acetate solutions are provided. Q show the calculation the volumes of the two solutions (acetic acid and sodium acetate) should be mixed for the preparation of the acetic buffer with pH 4.2 by the Henderson-Hasselbalch equation.
