If 4.381 g of sodium dihydrogenphosphate and 5.207 g of disodium hydrogenphosphate are dissolved in distilled water and diluted to 100.0 mL, and the pKa for the second ionization of phosphoric acid is 6.85, what is the expected pH of the resulting solution? You answer should have two decimal places and three significant figures.
