presented by Macmilan Learning The acetic acid/acetate buffer system is a common buffer used in the laboratory. To prepare an acetic acid/acétate buffer, a technician mixes 30.7 mlL of 0.0951 M acetic acid and 20.1 ml. of 0.112 M sodium acetate in a 100 ml volumetric flask and then fills with water to the 100 ml. mark. How many moles of acetic acid are present in this buffer? acetic acid: mol How many moles of sodium acetate are in the buffer? sodium acetate: mol
