Qhov sib txawv tseem ceeb ntawm qhov tseeb thiab muaj peev xwm electrolyte yog qhov tseeb electrolytes dissociate rau hauv ions kiag li whereas muaj peev xwm electrolytes dissociate rau ions ib feem.
Peb tuaj yeem faib txhua qhov sib xyaw ua ob pawg ua electrolytes thiab nonelectrolytes, nyob ntawm lawv lub peev xwm los tsim ions thiab ua hluav taws xob. Electrolysis yog cov txheej txheem ntawm kev hla tam sim no los ntawm cov tshuaj electrolytic thiab yuam cov ions zoo thiab tsis zoo txav mus rau lawv cov electrodes. Nonelectrolytes tsis tuaj yeem koom nrog hauv cov txheej txheem electrolysis.
Electrolyte yog dab tsi?
Muaj tseeb electrolytes yog cov khoom uas muaj peev xwm dissociate tag rau hauv nws cov ions. Cov no tseem muaj npe hu ua cov electrolytes muaj zog. Cov tebchaw no yooj yim tsim lawv cov ntawv ionic thaum yaj hauv dej lossis lwm yam tshuaj. Muaj ob qho cations thiab anions nyob rau hauv cov tshuaj tom qab lub compound dissociated; Yog li, cov ions tuaj yeem nqa hluav taws xob tam sim no los ntawm cov tshuaj electrolytic. Qhov no yog vim li cas rau nws lub npe "electrolyte", txhais tau tias "muaj peev xwm ua hluav taws xob".
Ib qho tshuaj muaj zog ntawm cov electrolyte muaj tseeb muaj qhov vapor siab dua li cov dej ntshiab ntawm qhov kub zoo sib xws. Cov kua qaub muaj zog, muaj zog hauv paus, cov ntsev ionic soluble uas tsis muaj zog acids thiab cov hauv paus tuaj yeem raug cais raws li cov khoom siv hluav taws xob tiag.
Daim duab 01: Ua tiav Kev Sib Tham
Thaum sau cov tshuaj tiv thaiv rau ionization ntawm ib qho hluav taws xob tiag tiag, peb tuaj yeem siv ib qho xub nyob rau hauv ib qho kev taw qhia los qhia qhov ua tiav cov tshuaj tiv thaiv ionization hauv qhov sib piv rau cov muaj peev xwm lossis tsis muaj zog electrolytes. Qhov no ib tug xub txhais tau hais tias cov tshuaj tiv thaiv tshwm sim kiag li. Muaj tseeb electrolytes tuaj yeem ua hluav taws xob tsuas yog thaum nyob hauv molten lossis cov ntsiab lus daws teeb meem. Txij li thaum ionization siab, qhov hluav taws xob uas muaj tseeb electrolyte tuaj yeem tsim tau siab heev.
Muaj Peev Xwm Electrolyte yog dab tsi?
Muaj peev xwm electrolytes yog cov tshuaj uas tuaj yeem cuam tshuam ib nrab rau hauv nws cov ions. Qhov no txhais tau hais tias nws tsis tuaj yeem cuam tshuam tag nrho rau hauv nws cov ions hauv cov tshuaj aqueous. Yog li ntawd, cov tshuaj aqueous ntawm lub peev xwm electrolyte yuav muaj ob hom ionic thiab un-dissociated molecules. Feem ntau, qhov dissociation ntawm lub peev xwm electrolyte yog li 1-10%. Cov no kuj muaj npe hu ua tsis muaj zog electrolytes. Qee cov piv txwv ntawm cov electrolytes tsis muaj zog muaj xws li acetic acid, carbonic acid, ammonia, phosphoric acid, thiab lwm yam. Cov no yog cov acids tsis muaj zog lossis tsis muaj zog hauv paus.
Daim duab 02: Tshuaj Reaction rau Dissociation of Acetic Acid
Thaum sau cov tshuaj tiv thaiv rau kev sib cais ntawm cov hluav taws xob tsis muaj zog, peb siv ob tug xib xub coj mus rau cov lus qhia. Cov xub no txhais tau hais tias muaj qhov sib npaug ntawm hom ionic thiab unionized molecules hauv cov kua dej.
Qhov txawv ntawm Qhov Tseeb thiab Muaj Peev Xwm Electrolyte yog dab tsi?
Raws li lawv lub peev xwm los tsim cov ions thiab ua hluav taws xob, peb tuaj yeem faib tag nrho cov tebchaw ua ob pawg ua electrolytes thiab nonelectrolytes. Electrolytes dua tau muab faib ua ob ntu raws li qhov tseeb thiab muaj peev xwm electrolytes. Qhov sib txawv tseem ceeb ntawm qhov tseeb thiab muaj peev xwm electrolyte yog qhov tseeb electrolytes dissociate rau ions kiag li thaum muaj peev xwm electrolytes dissociate rau hauv ions ib feem. Ntxiv mus, lub zog dissociation ntawm qhov tseeb electrolytes yog 100% thaum lub zog dissociation ntawm tej zaum electrolytes txawv ntawm 1 mus rau 10%.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov tseeb thiab muaj peev xwm electrolyte.
Summary – Muaj tseeb vs Muaj peev xwm Electrolyte
Muaj tseeb electrolytes yog cov khoom uas tuaj yeem cuam tshuam rau hauv nws cov ions thaum muaj peev xwm electrolytes yog cov khoom uas tuaj yeem cuam tshuam rau hauv nws cov ions. Yog li ntawd, qhov sib txawv tseem ceeb ntawm qhov tseeb thiab muaj peev xwm electrolyte yog qhov tseeb electrolytes dissociate rau hauv ions kiag li, whereas muaj peev xwm electrolytes dissociate rau hauv ions ib feem.
