Reaction of Acetic Acid with Hydroxide Ion Dr. Prem Sattsangi, Ph.D. and Cheryl Farren Tkacs (Instructional Designer) Lab 3 Preparation of Buffers

AcO - H+H+ OH - Acetic Acid Hydroxide enters Acetic acid and hydroxide Acetate ion + Water H+H+ AcO - H+H+

In conclusion… We start with 2 molecules of acetic acid. 1 molecule of hydroxide reacts with 1 molecule of acetic acid to produce 1 molecule of acetate and 1 molecule of water. After the reaction, we have 1 molecule of acetic acid, 1 molecule of acetate ion, and 1 molecule of water.
