Thaum cov tshuaj tsis muaj zog electrolyte yog diluted, qhov ntim ntawm cov tshuaj nce, yog li qhov sib npaug conductivity (λc) nce. Txawm li cas los xij, thaum tus txheej txheem no, tus naj npawb ntawm cov khoom nqa tam sim no ib cm3 txo.
Yuav ua li cas thaum tsis muaj zog electrolyte yog diluted?
Rau qhov tsis muaj zog electrolyte molar conductance hauv cov tshuaj dilute nce sharply raws li nws cov concentration hauv cov tshuaj txo.
Yuav ua li cas rau hluav taws xob conductivity ntawm qaug zog electrolyte nrog dilution?
Rau cov electrolytes tsis muaj zog (piv txwv li cov electrolytes tsis tiav), txawm li cas los xij, cov molar conductivity zoo nyob ntawm qhov concentration: Qhov ntau dilute cov tshuaj, qhov ntau dua nws cov molar conductivity, vim nce ionic dissociation.
Ib qho piv txwv ntawm cov electrolyte tsis muaj zog yog dab tsi?
Tsis muaj zog electrolytes ib nrab dissociate rau hauv ions hauv kev daws thiab yog cov hluav taws xob tsis muaj zog. Hom tsis muaj zog electrolytes muaj xws li qaug zog acids thiab bases. Piv txwv ntawm cov electrolytes tsis muaj zog muaj xws li acetic acid thiab mercury(II) chloride.
Vim li cas dissociation ntawm qaug zog electrolyte nce nrog dilution?
Hint: Cov degree ntawm dissociation ntawm ib tug tsis muaj zog electrolyte yog ncaj qha proportional rau lub square cag ntawm dilution vim hais tias ntawm dilution, nws dissociates rau hauv ions vim lub siab dielectric tas li ntawm dej los yog hnyav thiab ionstau nkag tau yooj yim yog li nce qib ntawm kev sib cais.
