PH OF BUFFERS - (Jun/29/2010 )


could someone please explain how the following question was done, i cant seem to get the same answer
thanks. the link is below.


the easiest way to use the acid and base forms of the same buffer is to make equimolar solutions of both and add one to the other until the desired pH is attained. that way, regardless of final volume, the buffer will remain at the original concentration.
