Potentiometrically titration

WebOf the 22 α-amino acids studied, all but five (tyrosine, cystine, cysteine, glutamic acid and aspartic acid) have been titrated potentiometrically with perchloric acid in two solvents, glacial acetic acid and 90% acetonitrile-acetic acid. The half-neutralisation potentials and the p′ values of the amino acids in th WebA reasonable standard would be “three titration masses within ± 3% of the mean mass”. If using 50-mL burets, increase the volume of the citric acid samples from 5 mL to 10 mL to have roughly the same precision in the results. 5b Student instructions Transfer about 10 mL of the citric acid solution into a small beaker ( 100 or 250 mL ).
