BUFFER CAPACITY EXPERIMENT

Part 1: Preparation and pH Meter Calibration

Prepare 50 mL of 0.5 M acetic acid from a concentrated stock.
Prepare 50 mL of 0.5 M sodium hydroxide from a solid.

Part 2: Buffer Capacity

Transfer 20 mL of 0.5 M acetic acid (K_a is 1.75*10^-5), stir at a slow setting and measure the pH reading is stabilized.
Add 1.0 mL of 0.5 M NaOH and measure the pH.
Continue adding 0.5 M NaOH in 0.5 - 1.0 mL increments until a major spike in pH occurs.
After the spike, add another two 0.5 – 1.0 mL increments of 0.5 M NaOH.
Create a pH vs. Volume graph to determine the range of the buffer’s capacity.
Compare the actual data (nonstandard conditions) with the theoretical data under standard conditions.
