A buffer solution based upon ascorbic acid (H2C6H6O6) was created by treating 1.00L of a 1.00 M ascorbic acid solution with NaOH until a pH of 3.602 was achieved (assuming no volume change). To this buffer 1.370 moles of NaOH were added (assume no volume change). What is the final pH of this solution? For this problem we can assume the 5% assumption is valid.
