Tswj muaj peev xwm coulometry : daim ntawv thov ntawm cov tshuaj tiv thaiv theem nrab rau kev txiav txim siab ntawm plutonium thiab uranium ntawm cov khoom electrode. Kev txiav txim siab yog ua los ntawm kev sib xyaw ntawm sulfuric thiab nitric acids, thiab Ti (III) yog siv los txo plutonium thiab uranium rau Pu (III) thiab U (IV) ua ntej electrolysis.
Ua kom pom qhov no, dab tsi yog tswj tam sim no coulometry?
Tswj tau - Tam sim no Coulometry . Yuav kom tswj tau qhov tsis tu ncua tam sim no peb yuav tsum tso cai rau lub peev xwm hloov. Yog tias qhov kev hloov pauv hauv qhov muaj peev xwm tso cai rau lwm hom kab mob oxidation lossis txo qis, ces tag nrho cov nqi tsis yog ib qho kev ntsuas ntawm qhov ntsuas ntawm peb cov qauv.
Ib yam li ntawd, txoj kev coulometric yog dab tsi? Coulometry yog ib qho analytical txoj kev rau ntsuas qhov tsis paub qhov concentration ntawm ib qho tshuaj ntsuam xyuas hauv kev daws los ntawm kev hloov pauv cov tshuaj ntsuam xyuas los ntawm ib lub xeev oxidation mus rau lwm qhov. Coumetry siv qhov chaw tsis tu ncua kom xa cov nqi ntsuas tus nqi.
Xav txog qhov no, dab tsi yog tswj tau muaj peev xwm electrolysis?
A tswj - peev xwm , tswj -tam sim no (c.p.c.c.) method for electrolysis tau tsim kho. Electrolysis yog ua raws li tswj oxidative thiab tswj reductive tam sim no nyob rau hauv preset sab sauv thiab sab bound peev xwm.
Thaum kuaj pom cov pa roj coulometric titration yuav siv li cas?
Cov Karl Fischer tshuaj tiv thaiv siv ib coulometric titration los txiav txim seb tus nqi dej hauv ib qho qauv. Nws ua tau txiav txim siab cov dej ntawm qhov kev txiav txim ntawm milligrams ib liter. Nws yog siv rau nrhiav cov dej hauv cov khoom xws li butter, qab zib, cheese, ntawv, thiab roj av.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Dab tsi yog 5 hom kev muaj peev xwm muaj zog?
Kev nthuav qhia, 5 Hom Muaj Peev Xwm Muaj Zog. Lub zog muaj peev xwm yog khaws cia lub zog uas tuaj yeem hloov mus rau kinetic zog. Muaj ntau hom kev siv zog xws li gravitational, magnetic, hluav taws xob, tshuaj, thiab elastic muaj peev xwm zog
Dab tsi yog qhov txawv ntawm electrostatic muaj peev xwm thiab electrostatic muaj peev xwm zog?
Tsis muaj qhov sib txawv ntawm electrostatic potentialenergy thiab hluav taws xob (al) muaj peev xwm zog. Lub peev xwm hluav taws xob ntawm ib qho taw tes yog kev ua haujlwm los ntawm lwm qhov kev quab yuam hauv kev txav chav tsev zoo los ntawm ib qho arbitrarilychosen xoom ntawm lub peev xwm (feem ntau infinity) mus rau lub ntsiab lus
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Puas muaj peev xwm equilibrium zoo ib yam li so muaj peev xwm?
Qhov sib txawv ntawm daim nyias nyias muaj peev xwm thiab qhov muaj peev xwm sib npaug (-142 mV) sawv cev rau lub zog hluav taws xob hluav taws xob uas tsav Na + mus rau hauv lub xovtooj ntawm lub peev xwm so membrane. Thaum so, txawm li cas los xij, qhov permeability ntawm daim nyias nyias mus rau Na + tsawg heev kom tsuas yog me me Na + xau rau hauv lub cell
