Isicelo

I-Potassium hydrogen phthalate ivame ukusetshenziselwa ukulinganisa izixazululo ezijwayelekile ze-sodium hydroxide ngenxa yokulula kwayo ukuthola imikhiqizo ehlanzekile ngokusebenzisa i-recrystallization, ukungabikho kwamanzi e-crystallization, i-non-hygroscopicity, isitoreji esilula, nokulingana okuphezulu; Ingase futhi isetshenziselwe ukulinganiswa kwesisombululo se-acetic acid nge-perchloric acid (kusetshenziswa i-methyl violet njengenkomba).
