Isicelo

I-potassium hydrogen phthalate ivame ukusetshenziselwa ukulinganisa izixazululo ezijwayelekile ze-sodium hydroxide ngenxa yokuthi kulula ukuthola imikhiqizo emsulwa ngokusebenzisa i-recrystallization, ukungabikho kwamanzi e-crystallization, ukunga-hygroscopicity, ukugcinwa okulula, kanye nokulingana okuphezulu; Ingasetshenziswa futhi ukulinganisa isixazululo se-acetic acid ne-perchloric acid (kusetshenziswa i-methyl violet njengesibonakaliso).
