Electrolysis ntawm a poov tshuaj nitrate daws tsim tawm oxygen ntawm anode thiab hydrogen ntawm cathode.
Ib yam li ntawd, dab tsi yog tsim nyob rau hauv electrolysis?
Electrolysis yog ib qho kev cog lus rau hydrogen ntau lawm los ntawm cov peev txheej txuas ntxiv mus. Electrolysis yog txheej txheem ntawm kev siv hluav taws xob los faib dej rau hauv hydrogen thiab oxygen. Cov tshuaj tiv thaiv no tshwm sim hauv ib chav hu ua electrolyzer.
Vim li cas hydrogen tsim ntawm qhov tsis zoo electrode thiab tsis potassium? Nyob ntawm tsis zoo electrode Hlau ions thiab hydrogen ions raug nqi zoo. Seb koj tau txais cov hlau los yog hydrogen Thaum lub sij hawm electrolysis nyob ntawm txoj hauj lwm ntawm cov hlau nyob rau hauv lub reactivity series: cov hlau yuav ua yog hais tias nws yog tsawg reactive tshaj hydrogen.
Kuj tseem paub yog, dab tsi yog tsim los ntawm cathode?
Cov electrolysis ntawm lwm cov tebchaw Tag nrho cov ionic compounds thaum molten tuaj yeem decomposed thaum hluav taws xob dhau los ntawm kev siv electrolysis. Cov hlau thiab hydrogen ib txwm ua ntawm lub cathode . Tsis yog-hlau ib txwm ua ntawm lub anode . Cations taug kev mus rau lub cathode.
Yuav ua li cas yog cov khoom ntawm electrolysis ntawm aqueous magnesium iodide?
Kev piav qhia: Magnesium iodide yog ib tug soluble ionic compound uas dissociates kiag li thaum yaj nyob rau hauv dej rau tsim tawm magnesium cations thiab iodide anions hauv dej daws. Koj ua tau tam sim no hais tias thaum twg magnesium iodide yaj hauv dej, nws tsim Mg2 + thiab I- ions.

Puas yog kev sib xyaw potassium chloride nrog sodium nitrate muaj tshuaj tiv thaiv?
Tsis yog nws tsis yog vim tias ob qho tib si potassium chloride thiab sodium nitrate tsim cov tshuaj aqueous, uas txhais tau hais tias lawv yog soluble. Lawv yaj hauv dej kom tiav, uas txhais tau hais tias tsis muaj cov tshuaj tiv thaiv pom hauv cov khoom. Thaum peb sib xyaw KCl nrog NaNO3, peb tau KNo3 + NaCl. Qhov sib npaug ionic rau qhov sib tov yog
Dab tsi ions tsim thaum barium nitrate yaj hauv dej?
Thaum Ba(NO3)2 yaj nyob rau hauv H2O (dej) nws yuav dissociate (dissolve) rau hauv Ba 2+ thiab NO3- ions
Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Yuav ua li cas thaum MgCl2 Electrolysed?
Thaum MGCL2 yog electrolysed ces MG2 + ion tso rau ntawm lub anode thiab 2CL-ion yog tso rau ntawm lub cathode. Lub 2CL-ion poob nws 2 electron thiab dhau los ua CL2 (gas). Yog li ntawm electrolysis ntawm MGCL2 peb tau txais MG thiab CL2 (gas)
Yuav ua li cas thaum koj sib tov sodium chloride thiab potassium nitrate?
Yuav ua li cas sodium chloride thiab potassium nitrate teb ua ke? Yog li, koj yuav tau txais tsuas yog ib homogeneous sib tov ntawm ob ntsev, muaj cov Na +, Cl-, K + thiab NO3- ions hauv dej. Yog tias koj rhaub cov khoom sib tov ntawm ob cov ntsev, tsuas yog cov nitrate yuav decompose rau nitrite nrog cov evolution ntawm oxygen
