Desribe the preparation of 2.00 L of 0.100M pH 9.00 glycine starting with the sodium chloride salt of zwitterionic glycinhe 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 alpha amino groups of glycine are 2.35 and 9.78, respectively.)
