Codsiga

Potassium hydrogen phthalate waxaa sida caadiga ah loo isticmaalaa hagaajinta xalalka caadiga ah ee sodium hydroxide sababtoo ah sahlanaanta helitaanka alaabada saafiga ah iyada oo loo marayo recrystalization, maqnaanshaha biyaha crystallization, aan hygroscopicity, kaydinta fudud, iyo u dhigma sare; Waxa kale oo loo isticmaali karaa in lagu qiyaaso xal acetic acid leh perchloric acid (iyadoo la isticmaalayo methyl violet sida tilmaame).
