Sulfuric Acid (H2SO4). siv hauv redox titration txheej txheem vim nws muab cov H(+) ions tsim nyog rau cov tshuaj tiv thaiv tshwm sim sai dua thaum lub sulphate (-) ions NW nyuam qhuav tshwm sim thaum lub sij hawm cov tshuaj tiv thaiv. Yog li ntawd, sulfuric acid yog ntxiv los ua cov tshuaj acidic.
Yog li ntawd, vim li cas Sulfuric acid siv nyob rau hauv redox titration es tsis txhob HCL?
Raws li dilute sulfuric acid yog zoo tagnrho rau redox titration vim nws tsis yog tus neeg sawv cev oxidizing thiab tsis yog tus neeg sawv cev txo qis. HCL yog ib tug muaj zog electrolyte dissociates nyob rau hauv dej muab H + thiab Cl-ions. Yog li ntawd, qee qhov nyiaj ntawm KMnO4 yog siv nce hauv oxidising Cl- rau Cl2. Ib sab ntawm KMnO4 yog oxidising oxalate ion rau CO2.
Ib sab saum toj no, lub hom phiaj ntawm redox titration yog dab tsi? Txiav txim siab Concentration ntawm ib qho Analyte Raws li nrog acid-base titrations , a redox titration (tseem hu ua oxidation-txo titration ) tuaj yeem txiav txim siab qhov concentration ntawm qhov ntsuas tsis paub los ntawm kev ntsuas nws tawm tsam tus qauv titrant.
Yog li ntawd, yog vim li cas sulfuric acid siv nyob rau hauv ib tug permanganate titration?
Sulfuric acid yog siv vim nws ruaj khov rau oxidation; Piv txwv li, hydrochloric kua qaub yuav tau oxidized rau chlorine los ntawm poov tshuaj permanganate.
Vim li cas HCL tsis siv hauv redox titration?
Cov kua qaub siv hauv qhov no titration yog dilute sulfuric acid. Nitric acid yog tsis siv Raws li nws yog nws tus kheej tus neeg sawv cev oxidising thiab hydrochloric acid feem ntau yog zam vim nws hnov mob nrog KMnO4 raws li qhov sib npaug muab rau hauv qab no los tsim cov tshuaj chlorine thiab chlorine uas tseem yog tus neeg sawv cev oxidising hauv cov kua dej.

Koj puas tuaj yeem siv sulfuric acid hauv chav dej?
Lub chav dej ua haujlwm zoo yog qhov tsim nyog hauv tsev neeg niaj hnub no. Kev ntxuav tawm hauv chav dej nrog cov khoom siv tshuaj, xws li sulfuric acid, feem ntau tuaj yeem tshem tawm qhov thaiv thiab rov ua haujlwm rau koj lub chav dej. Txawm li cas los xij, koj yuav tsum tau ceev faj, vim tias sulfuric acid yog ib qho tshuaj lom heev
Vim li cas qhov ntsuas tsis siv hauv kmno4 titration?
Vim li cas qhov ntsuas tsis siv nyob rau hauv titration ntawm poov tshuaj permanganate nrog oxalic acid? Cov xim ntawm permanganate yog qhov ntsuas. Thawj qhov poob ntawm ntau tshaj MnO4- yuav muab cov xim liab mus tas li rau cov tshuaj tiv thaiv-yog li tsis tas yuav muaj qhov ntsuas ntxiv
Vim li cas cov kua qaub nruab nrab tsim nyog hauv redox titration?
Muaj ob qhov laj thawj: Txhawm rau muab hydrogen ions rau cov tshuaj kom acidify nws. Qee qhov redox (xws li permanganate) muaj peev xwm oxidation zoo dua yog tias ua tau rau hauv qhov chaw acidic. Lub sulfate ion yog ib qho nyuaj ion rau oxidise nyob rau hauv ib txwm redox titrations, yog li koj tsis nquag tau byproducts
Yuav ua li cas ua hydrochloric acid los ntawm sulfuric acid?
Ua ntej, koj yuav ncuav ib co ntsev rau hauv lub lauj kaub distil. Tom qab ntawd, koj yuav ntxiv ib co concentrated sulfuric acid rau ntsev. Tom ntej no, koj yuav cia cov no cuam tshuam nrog ib leeg. Koj yuav pib pom gasses npuas thiab cov roj hydrogen chloride tshaj tawm los ntawm lub raj sab saum toj
Vim li cas Dil h2so4 siv hauv KMnO4 titration?
Raws li dilute sulfuric acid yog zoo tagnrho rau redox titration vim nws tsis yog ib tug oxidizing tus neeg saib xyuas thiab tsis yog ib tug txo tus neeg sawv cev. HCL yog lub zog electrolyte dissociates hauv dej kom muab H + thiab Cl-ions. Li no, qee qhov nyiaj ntawm KMnO4 yog siv los ua oxidising Cl- rau Cl2. Ib sab ntawm KMnO4 yog oxidising oxalate ion rau CO2
