Describe the preparation of 2.00 L of 0.100M pH 9.00 glycine buffer starting with the sodium chloride salt of zwitterionic glycine and 1.00M NaOH. If a reaction that generated 2.00 mmoles of base were carried out in 100 mL of the above buffer, what would be the final solution pH? (The pKa values of the carboxyl and protonated a-amino groups of glycine are 2.35 and 9.78, repectively.)
