Academics

A solution (100 mL) containing the diprotic weak acid, leucine (amino acid), at a concentration of 0.0005 M was titrated with 0.005 M NaOH (strong base). Calculate the pH at the following points (volumes of NaOH added) along the titration curve for leucine. Also, sketch the titration curve for this concentration and volume of leucine with NaOH. a. 0 mL of NaOH added b. 5 mL of NaOH added c. 10 mL of NaOH added d. 15 mL of NaOH added e. 20 mL of NaOH added f. 25 mL of NaOH added Ka1= 4.69 x 10^-3 Ka2= 1.79 x 10^-10
