2. Write reaction equations to explain how your acetic acid-acetate buffer reacts with an acid and reacts with a base. 3. Identify the Pka of acetic acid from your data. Advanced Chemistry with Vernier Buffers 4. Buffer capacity is usually defined as the pKa Il pH unit- that is, the pH range over which the ratios of protonated to unprotonated form of the buffer go from 10:1 to 1:10. Use your data to determine the buffer capacity of your buffer...
