A biochemist prepares two stocks of sodium phosphate buffer by titrating phosphoric acid with sodium hydroxide. She prepares a 0.10 M solution of sodium phosphate buffer at pH 7.20, and she prepares a 0.10 M solution of sodium phosphate buffer at pH 12.35. If she mixes 50. mL of the pH 7.20 buffer with 30. mL of the pH 12.35 buffer, what will be the pH of the resulting solution? The pKas of phosphoric acid are 2.15, 7.20, and 12.35.
