what concentration of acetic acid and acetate would
What concentrations of acetic acid (pKa - 4.76) and acetate would be required to prepare a 0.20 M buffer on and/or pH value may differ from that in the first question. solution at pH 4.6? Note that the concentrati STRATEGY 1. Rearrange the Henderson-Hasselbalch equation to solve for the ratio of base (acetate) to acid (acetic acid), [A VHA 2 Use the mole fraction of acetate to calculate the concentration of acetate. 3. Calculate the concentration of acetic acid. Step 1: Rearrange the Henderson Hasselbalch equation to solve for HA] The Henderson-Hasselbalch equation is HA Use the Henderson-Hasselbalch equation to solve for if the solution is at pH 4.6. [HA] Number Enter your answer as a number. For example, 9.6. Do not enter a formula like 1062 HA
