Make 500mL of a 0.200 M acetate buffer at pH 5.00 using simply pure acetic acid (MW=60.05 g/mol, pKa=4.76), 3.00 M NaOH and water. Answer the subsequent questions regarding the preparation of the buffer.
1. Explain how many grams of acetic acid will you require to prepare the 500mL buffer? Note that the given concentration of acetate refers to the concentration of all acetate species in solution.
2. Define what volume of 3.00 M NaOH should you add to the acetic acid to achieve a buffer with a pH of 5.00 at a final volume of 500mL?
