if you want to prepare a buffer at pH = 5.2 which buffer would you choose?

a) MES --> Ka = 7.9 x 10^-7

b) CHES --> Ka = 5.0 x 10^-7

c) Tris --> Ka = 6.3 x 10^-9

d) acetic aid --> Ka = 1.8 x 10^-5

Expert Solution

Thus the pKa of acetic acid is very close to the pH of given buffer hence we use d) acetic acid --> Ka = 1.8 x 10^-5

How would you prepare 10L of 0.045M potassium phosphate buffer, pH 7.5? You can use the Henderson-Hasselbalch equation to calculate how much of each chemical species. This ratio will tell you how much of the 10L comes from the [A-} species, and how much from the [HA] species, giving you the volumes for your next calculation. Then you have to figure out how much of each to weigh out to make that calculated volume at 0.045M for each species. The...
