1 A buffer is prepared by mixing 50.0 mL of 0.100 M acetic acid with 30.0 mL of 0.100 M sodium hydroxide and 20.0 mL of distilled water. Estimate the concentration of acetic acid in the resulting buffer. Report your answer in moles/liter, but do not include units with your answer. 2 Determine the concentration of acetate ions in the buffer solution. Report your answer in moles per liter, but do not include units in your answer. 3 Estimate the pH of the buffer solution using the Henderson-Hasselbalch equation. 4 Using the Henderson-Hasselbalch equation, estimate the pH of the buffer if an additional 10.0 mL of 0.100 M sodium hydroxide is added. 5 Estimate the pH of the original buffer if 10.0 mL of 0.100 M hydrochloric acid is added.
