I) Calculate the milliliters of NaOH solution, and the grams of NaCl, necessary to create 50.00 mL of a pH = 5.00 buffer at an ionic strength of 0.1000. Use: Activities, alpha(Ac-), the charge balance equation, and the ionic strength equation. II) Calculate the milliliters of NaOH solution necessary to create 50.00 mL of a pH = 5.00 buffer. Use: the Henderson-Hasselbalch Equation, only. *** You will begin parts (I) and (II) with 20.00 mL of 0.04934 M HAc (acetic acid). In both parts, you will calculate the required milliliters of 0.05678 M NaOH. ***
