Isicelo

I-Potassium hydrogen phthalate isetyenziswa ngokuqhelekileyo ukulinganisa izisombululo ezisemgangathweni ze-sodium hydroxide ngenxa yokulula kwayo ukufumana iimveliso ezihlambulukileyo ngokusebenzisa i-recrystallization, ukungabikho kwamanzi e-crystallization, i-non-hygroscopicity, ukugcinwa lula, kunye nokulingana okuphezulu; Ingasetyenziselwa ukulinganisa isisombululo se-acetic acid nge-perchloric acid (usebenzisa i-methyl violet njengesalathisi).
