4. Example on how to make up a buffer: A student has 110 mL of 0.15 M acetic acid and has plenty of 0.15 M sodium acetate and wants to make up a buffer with pH = 5.10 Using the pKa of acetic acid/sodium acetate 4.74 and the equation pH =pKa + log[base]/ [acid] How many mL of sodium acetate will she need? What is the final concentration (in molarity) of the sodium acetate and the acetic acid. Use this information to prove that the student has correctly calculated the volume of sodium acetate that she needs.
