1 Describe what a buffer consists of and what purpose it serves. 2) A student adds 3.0 mL of 0.50 M acetic acid and 7.0 mL of 0.50 M sodium acetate to a beaker and then adds 90.0 mL of water. Calculate the pH of this buffer using the Henderson-Hasselbalch equation Calculate the pH of a buffer prepared the same way as in question 2, but with 7.0 mL of 1.0 M sodium acetate instead of 0.50 M sodium acetate. 3)
