MUBODILAI IONI

MUBODILAI IONI, mubodilai ionhoro dar mahluli elektrolitho guyand. Mubodilai ioni du khel meshavad: yakjinsa (gomogeni) va gunogunjinsa (geterogeni). Mubodilai ionii yakjinsa dar mahluli elektrolitho ba vujud meoyad. Hangomi omekhtani mahlulhoi serobi elektrolitho mas., NaCl pa KN03l dar omekhta nonhoi Na+, K+, N03— va S1- vujud dorand. Dar in bobat holati muvozinat bo muodilai NaCl + KN03 NaN03 + KS1 (reaksiyai mubodilai duchanda) ifoda karda meshavad. Agar moddai hosilshavanda nisbat ba digarash kamtar dissosiasiya shavad, muvozinat ba tarafi moddai kamdissosiasiyashavanda va hangomi hosil shudani moddahoi tezbukhorshavanda yo kamhalshavanda (agar vay ae fazai mazkur judo shavad) muvozanat ba tarafi in moddaho mayl mekunad. Dar Mubodilai ionii gunogunjinsa (sorbsiyai mubodilaiioni) mubodila dar bayni ionhoi dar mahlulbuda va ionhoi dar rui fazai sakhtbuda — ionit ba vujud meoyad. Mubodilai ionii gunogunjinsa baroi benamakgardonii obi baroi deghoi bugi dodashavanda, dar gidrometallurgiya, sanoati khimiya va farmasevti istifoda meshavad.
