You need the buffers mathematical equation, and to be able to identify each speices.
Ka = [H+] x (A-/HA)
Ka is the Ka of the acid HA
[H+] is your pH term (your answer in most cases)
A- is the conjugate species of the acid HA
HA is the acid that we have the Ka value for...
Setting up the BUFFER equation...
Ka = [H+] x 0.250/0.100
From this we can find the pH before the ...
