You add 147.25g of potassium acetate (KCH3COO, MW 98.15 g/lol) to 250mL of distilled water. You adjust the pH to 5.5 with a volume of glacial acetic acid (17.4M, CH3COOH, pKa=4.75) and qs the remaining volume to 500mL with distilled water. How much glacial acetic acid did you have to add to make 500mL of a pH 5.5 buffer?
