Hauv a potentiometric titration cov qhov kawg yog txiav txim siab los ntawm kev siv ib khub ntawm cov electrodes lossis cov electrode ua ke. Cov qhov kawg tshwm sim qhov twg muaj qhov siab tshaj plaws ntawm kev hloov pauv ntawm qhov muaj peev xwm ntawm qhov kawg ntawm titration.

Hauv qhov no, dab tsi yog qhov kawg potentiometric?

Potentiometric titration yog cov txheej txheem volumetric uas muaj peev xwm nruab nrab ntawm ob lub tshuab hluav taws xob raug ntsuas (ntsuas thiab ntsuas qhov ntsuas hluav taws xob) raws li kev ua haujlwm ntawm cov tshuaj reagent ntxiv. Thawj qhov piv txwv, ΔE/ΔV, yog txoj kab nqes ntawm txoj kab nkhaus, thiab qhov kawg tshwm sim ntawm qhov ntim, V ', qhov twg ΔE/ΔV muaj tus nqi siab tshaj.

Qhov thib ob, qhov ntsuas twg yog siv hauv kev ntsuas lub zog loj? Redox Titration: Hom kev ntsuas tus lej muaj zog cuam tshuam nrog kev tshuaj xyuas thiab kev saib xyuas uas ua rau redox cov tshuaj tiv thaiv . Ib qho piv txwv ntawm hom titration no yuav yog kev kho cov tshuaj iodine nrog txo tus neeg sawv cev uas tsim cov iodide ion (cov hmoov txhuv nplej siab tau qhia kom pom qhov kawg).

Ib yam li ntawd, kev siv cov tshuaj titration zoo li cas?

Potentiometric titration cuam tshuam nrog kev ntsuas qhov muaj peev xwm ntawm qhov ntsuas pom zoo electrode nrog kev hwm rau cov khoom siv hluav taws xob siv raws li kev ua haujlwm ntawm cov ntsiab lus ntim. Titration koom nrog ntsuas thiab sau cov peev xwm ntawm tes (hauv chav ntawm millivolts lossis pH) tom qab txhua qhov ntxiv ntawm titrant.

Vim li cas qhov ntsuas tsis tau siv hauv kev ntsuas titration potentiometric?

Potentiometric titration yog cov txheej txheem zoo ib yam li ncaj qha redox titration cov tshuaj tiv thaiv Nws yog qhov muaj txiaj ntsig txhais tau tias ua tus yam ntxwv. Tsis muaj qhov taw qhia yog siv ; hloov pauv qhov peev xwm yog ntsuas thoob plaws qhov ntsuas, feem ntau yog cov tshuaj electrolyte.

Koj yuav qhia tau li cas yog tias koj muaj pwm nyob hauv koj lub ntsws?

Kev kis tus kab mob kuj tseem tuaj yeem ua rau mob hawb pob lossis mob ntsws hauv cov neeg uas muaj mob ntsws ua ntej. Yog tias lawv cuam tshuam nrog pwm, lawv yuav ntsib cov tsos mob, xws li: los ntswg lossis txhaws qhov ntswg. dej, qhov muag liab. hnoos qhuav. daim tawv nqaij ua pob. mob caj pas. mob sinusitis. hawb pob

Cov cai hauv xeev feem ntau xav kom txhua tus neeg, suav nrog cov neeg ua haujlwm lossis lwm tus neeg mob, yuav tsum muaj tsawg kawg 2 metres ntawm xoo hluav taws xob, lossis thaj chaw raug mob ntawm tus neeg mob lub cev, lossis tiv thaiv los ntawm cov hmoov txhuas

Koj yuav paub li cas yog tias koj muaj lub cev tsis muaj zog?

Cov tsos mob thiab cov tsos mob ntawm tus thawj immunodeficiency muaj xws li: nquag thiab rov ua mob ntsws, mob ntsws, mob ntsws, mob pob ntseg, mob meningitis lossis kab mob ntawm daim tawv nqaij. Kev ua paug thiab kis kab mob hauv nruab nrog cev. Teeb meem ntshav, xws li suav cov platelet tsawg lossis tsis muaj ntshav
