Question

Which givens a better measure o4 the pH: universal pH paper of a pH meter? Can distilled water be an effective butter? Use data from your experimented to support your answer. Which of your buffer systems (a, b, c, or d) was the most effective in resisting a change in pH? How does your data support this conclusion? You have a buffer system made up of equimolar amounts of carbotic acid, H_2 CO_3, and sodium bicarbonate, NaHCO_3. Write equations to show how this buffer behaves when HCl is added and NaOH is added. Calculate the expected pH values of the buffer systems from the experiments (a, b, c, d), using the Henderson-Hasselibalch equation shown in the Background section. Use for pK_a values; carbonic acid = 6.37 and acetic acid = 4.75.

Explanation / Answer
