What amino acid would provide a suitable buffer at pH 7.0 when made up with NaOH and why? How many grams of this amino acid and what volume of the 0.1 mol/L NaOH would you mix to make 500 mL of a 0.01 mol/L solution of this buffer? (HINT: Having mixed the amino acid and the NaOH, you are expected to dilute to a final volume of 500 mL with distilled water.
