Kev coj uayog ib qho kev ntsuas ntawm cov dej muaj peev xwm kom dhau hluav taws xob ntws.Qhov peev xwm no ncaj qha ntsig txog qhov concentration ntawm ions hauv dej
1. Cov khoom siv hluav taws xob no yog los ntawm cov ntsev yaj thiab cov khoom siv tsis zoo xws li alkalis, chlorides, sulfides thiab carbonate compounds.
2. Cov tshuaj uas yaj mus rau hauv ions kuj hu ua electrolytes 40. Qhov ntau ions uas tam sim no, cov dej conductivity ntau dua.Ib yam li ntawd, tsawg dua ions uas nyob hauv dej, qhov tsawg dua nws yog.Cov dej distilled los yog deionized tuaj yeem ua raws li cov khoom siv hluav taws xob vim nws cov nqi qis heev (yog tias tsis tsim nyog) conductivity nqi.Dej hiav txwv, ntawm qhov tod tes, muaj cov conductivity siab heev.
Ions ua hluav taws xob vim lawv cov nqi zoo thiab tsis zoo
Thaum electrolytes yaj nyob rau hauv dej, lawv muab faib mus rau hauv zoo charged (cation) thiab negatively charged (anion) hais.Raws li cov khoom yaj hauv cov dej sib cais hauv dej, qhov sib npaug ntawm txhua qhov zoo thiab qhov tsis zoo nyob sib npaug.Qhov no txhais tau hais tias txawm tias cov dej conductivity nce nrog cov ions ntxiv, nws tseem muaj hluav taws xob tsis zoo 2
