Suppose you wish to make a buffer whose pH is 7.60. You have available 1 L of 0.200 M NaH₂PO4 and solid Na₂HPO4. How many grams of solid Na₂HPO4 must be added to the stock solution to accomplish this task? Assume the volume remains exactly 1 L. Ka(H₂PO4) = 6,2x10-8 pka(H₂PO4) = 7.21 Molar mass Na₂HPO4 = 141.95 g/mol 9 Na₂HPO4
