Weigh out 82.0 g of anhydrous sodium acetate and place
into a 1 L volumetric flask. Add approximately 600 mL of
17.8 MW-cm deionized water and swirl to dissolve. When
the salt has dissolved completely, fill up to the mark with
17.8 MW-cm deionized water. Filter the resulting solution
through a 0.2 mm filter.
