equivalence point of an acid base reaction has been determined using an indicator In this experiment we are going to monitor the changes in pH that occurs during the titration of a weak polyprotic acid with a strong baseAmino acid titration • From the amino acid titration curve, we can get important information about amino acid, for example pKa and also the pI • Amino acids have more than one pka, because it is polyprotic contain more than one ionizable groups • Also it provides information about the buffering range of the amino acid that is studiedResponsive Tables A responsive table will
