If you have a weak acid such as acetic acid (pka=4.0) at which pH ranges would you expect it to be a good buffer?
Homework Answers
Every buffer has some buffer capacity.
The general range of buffer is pKa±1
i.e lower range is pka -1 and upper range is pka+1
given pKa=4
lower range =4-1 =3 ; upper range pka+1 =4+1 = 5
so it act as buffer in the ph range of 3.0 - 5.0

Which of the following compounds would make the best buffer at pH 7.5? Acetic acid, pKa= 4.76 N-tris(hydroxymethyl) methylglycine (Tricine), pKa = 8.15 N-2-hydroxyethylpiperazine-N’-ethansulfonic acid, pKa2= 7.6 Glycine, pKa2= 9.9 Tris(hydroxymethyl)aminomethane (Tris), pKa = 8.3 I believe 3 is the correct answer and therefore I am trying to answer the below question with this information. Using the answer that you selected from question 1 above: a. Explain how you would make the buffer starting with 1M HA and 1M A-...
