Kev coj uayog ib qho kev ntsuas ntawm dej lub peev xwm los hla cov hluav taws xob. Lub peev xwm no muaj feem cuam tshuam ncaj qha rau qhov kev sib sau ua ke ntawm cov ions hauv dej
1. Cov ions conductive no los ntawm cov ntsev yaj thiab cov khoom inorganic xws li alkalis, chlorides, sulfides thiab carbonate compounds
2. Cov tshuaj uas yaj mus ua ions kuj hu ua electrolytes 40. Cov ions ntau dua uas muaj, qhov siab dua qhov conductivity ntawm dej. Ib yam li ntawd, qhov tsawg dua ions uas nyob hauv dej, qhov tsawg dua conductivity nws. Dej distilled lossis deionized tuaj yeem ua haujlwm ua ib qho insulator vim nws qhov qis heev (yog tias tsis tsis tseem ceeb) conductivity nqi.
3. Dej hiav txwv, ntawm qhov tod tes, muaj kev coj hluav taws xob siab heev.
Cov ions ua hluav taws xob vim lawv cov nqi zoo thiab tsis zoo
Thaum cov electrolytes yaj hauv dej, lawv faib ua cov khoom me me uas muaj nqi zoo (cation) thiab cov khoom me me uas muaj nqi tsis zoo (anion). Thaum cov khoom yaj faib ua dej, qhov sib xyaw ntawm txhua qhov nqi zoo thiab tsis zoo tseem sib npaug. Qhov no txhais tau tias txawm tias qhov conductivity ntawm dej nce ntxiv nrog cov ions ntxiv, nws tseem tsis muaj hluav taws xob.
