Worksheet: Buffer pH Changes
In this worksheet, we will practice using ionization equilibrium constants to find the change in a buffer pH when an acid or base is introduced.
Acetate buffers are used in biochemical studies of enzymes and other chemical components of cells to prevent pH changes that might change the biochemical activity of these compounds.
An acetate buffer is made such that it is 0.10 M in acetic acid and 0.10 M in sodium acetate. By how much does the pH of the buffer change after 1.0 mL of is added to 100 mL of this buffer, giving a solution with a volume of 101 mL? Take of to be .
