which of the following has the highest buffer capacity?
A 0.10M H2PO4-/0.10M HPO4 -2
B 0.50 M H2PO4-/0.10 M HPO 2-
C 0.10 M H2PO4-/0.50 M HPO4 2-
D 0.50 M H2PO4-/0.50M HPO4 2-
E They all hae the same buffer capacity.
There is a group of us working together.

Then look at the answers I gave to this question earlier. The best buffer for a particular solution is one in which the pKa of the buffer is in the range of the desired pH and when the term, log (base/acid) is 0.
