What is the composition of a buffer solution of pH 7.4 made by mixing 0.1 M NaH2PO4 and 0.1 M Na2HPO4. [Ka for NaH2PO4 = 6.22x10-8 M).
How to approach this question because evrything is given which can be pleaced in the Handerson-Hassalbach equation. But what we will get....?? Help please...

Since the molarities for both are the same, the ratio of moles = ratio of volumes, and that's the answer ie. 'composition' of buffer solution.
