Suppose you want to do a physiological experiment that calls for apH 6.5 buffer. You find that the organism with which you areworking is not sensitive to the weak acid H2X(Ka1=2 x 10-2 and Ka2=5.0 x10-7) or its sodium salts. You have available a 1.0Msolution of this acid and a 1.0M solution of NaOH. How much of the NaOH solution should be added to 1.0L of the acid to give a bufferat pH 6.50? (Ignore any volume change).
