Abuffer is made by weighing accurately 6.45 grams of anhydrous sodium acetate and dissolved in a volumetric flask to reach a volume of 100 ml while 1.14 ml of glacial acetic acid is placed into another 100 ml volumetric flask and diluted. 50 ml of sodium acetate solution and 50 ml of acetic acid are pipetted into a volumetric flask to make one buffer. write the chemical equation of the experiment.
