Kev coj hluav taws xob yog qhov ntsuas ntawm dej lub peev xwm hla dhau 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 cov ions kuj hu ua electrolytes.
3. Yog muaj ntau cov ions, qhov conductivity ntawm dej yuav siab dua. Ib yam li ntawd, qhov tsawg dua cov ions uas nyob hauv dej, qhov conductivity nws yuav tsawg dua. Dej distilled lossis deionized tuaj yeem ua haujlwm ua ib qho insulator vim nws qhov conductivity qis heev (yog tias tsis tseem ceeb). Dej hiav txwv, ntawm qhov tod tes, muaj conductivity 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.
