WebTherefore, to make 1 L of acetate buffer, use 150 mL of sodium acetate and 850 mL of acetic acid. Choice of Weak Acid for a Buffer Which of these compounds would be the best buffer at pH 5: formic acid (pKa 3), acetic acid (pKa 4), or ethylamine (pKa 9)? Briefly justify your answer. Answer Acetic acid; its pKa is closest to the desired pH. 0. 2. WebStrong acids ionize completely when they are dissolved in water, while weak acids ionize only slightly. As an example, glacial acetic acid has an acid dissociation constant of 1.75 x 10-5. A 10 M solution of acetic acid has a percent ionization of only 0.132 %. However, a 0.10 M solution has a percent ionization of 1.32 %.
