2. You made a pH=9.8 buffer solution by mixing NaOH and glycine to give a solution that is 0.20 M in total concentration of glycine. (pkal-2.34 and pka2=9.69) a) What 2 glycine species are present in the buffer solution at this pH? (draw their structures) b) What is the concentration ratio of these 2 species? c) How many moles of each species, A and HA, is there in 500 ml of the buffer solution.
