Question

Glycine solution was titrated against NaOH and pH of the final solution was 4.8. Given that the pKa¹ and pKa² of glycine are 2.34 and 9.60, respectively. Calculate the concentration of the dissociated amino acid in terms of the undissociated amino acid, if [x] and [y] are the concentrations of dissociated and undissociated amino acid, respectively.
