2. Using the Henderson-Hasselbalch equation, calculate the concentration ratio ([sodium acetate]/[acetic acid], the amount (number of mole)of acetic acid and sodium acetate, and the volume of 0.1 M acetic acid and 0.1M sodium acetate solutions needed to prepare 110 mL each of the following buffer solutions with concentration of 0.1M: a. Buffer 4, pH 3.76 Same approach as Buffer 1. Refer to the summary table for the preparation of buffers (Table 4). b. Buffer 5, pH 4.76 Same approach as Buffer 1. Refer to the summary table for the preparation of buffers (Table 4). c. Buffer 6, pH 5.76 Same approach as Buffer 1. Refer to the summary table for the preparation of buffers (Table 4).
