3 Kev coj ua. Conductometry yog siv txhawm rau txheeb xyuas hom ionic thiab saib xyuas cov tshuaj tiv thaiv tshuaj los ntawm kev kawm cov electrolytic conductivity electrolytic conductivity Conductivity yog ib qho kev ntsuas ntawm lub peev xwm ntawm cov tshuaj aqueous los hloov cov hluav taws xob tam sim no. Cov tam sim no yog nqa los ntawm ions, thiab yog li ntawd cov conductivity nce nrog cov concentration ntawm ions tam sim no nyob rau hauv kev daws, lawv mus, thiab kub ntawm cov dej. https://www.sciencedirect.com › khoom-science › conductivity
Kev coj ua - kev saib xyuas | ScienceDirect Topics
ntawm cov hom reacting lossis cov khoom tshwm sim. Nws muaj cov ntawv thov tseem ceeb hauv kev tshuaj ntsuam chemistry.
Tus Conductometer ua haujlwm li cas?
Hluav taws xob conductivity yog ntsuas los ntawm kev coj ntawm ob lossis plaub lub electrodes siv amperometric lossis potentiometric txoj kev. … Ob lub electrodes no dhau ib qho tam sim no los ntawm cov qauv ntawm ib zaus thiab qhov ntau ions tam sim no, qhov siab dua EC nyeem.
YYuav siv cov conductivity yog dab tsi?
Kev coj ua yog ntsuas qhov kev daws teeb meem ua hluav taws xob zoo npaum li cas. Txhawm rau nqa cov tshuaj tam sim no yuav tsum muaj cov khoom siv hluav taws xob, lossis ions. Kev ntsuas kev ntsuas feem ntau yog ua nyob rau hauv cov tshuaj aqueous, thiab cov ions lub luag haujlwm rau cov conductivity yog los ntawm electrolytes yaj hauv dej.
Tus Conductometer ntsuas dab tsi?
Conductivity metertso cai rau peb ntsuas qib ntawm kev coj ua hauv kev daws teeb meem. Conductivity yog ib lub peev xwm ntawm cov ntaub ntawv (kev daws teeb meem, hlau los yog gases) kom dhau ib qho hluav taws xob tam sim no. … Ob peb yam uas cuam tshuam kev ntsuas ntsuas yog qhov kub, qhov siab ntawm ions, thiab qhov xwm ntawm ions tam sim no hauv cov tshuaj.
EC meter siv li cas?
EC yog dab tsi? Hluav taws xob conductivity (EC) yog ntsuas ntawm tag nrho cov soluble thiab yaj ntsev hauv cov tshuaj. EC yog ntsuas nyob rau hauv units ntawm hluav taws xob nqi. Dissolved as-ham thiab tsis tseem ceeb ions xws li sodium thiab chloride tag nrho pab rau EC.
