Cov sodium hydroxide yuav hnov mob nrog cov pa roj carbonic acid los ua sodium carbonate. … Qhov txiaj ntsig yog tias dhau sijhawm lub zog ntawm cov tshuaj NaOH yuav txo qis thiab tsis tuaj yeem ua kom raug cov kua qaub ntxiv lawm.
Vim li cas cov burette ntxuav hauv sodium hydroxide tov ua ntej pib titration?
Yog vim li cas koj yaug nrog sodium hydroxide yog vim thaum twg koj ntxuav, ib qho dej me me nyob hauv lub buret thiab nws yuav tsum tau ntxuav ua ntej qhov kev sim pib, lossis nws yuav Hloov cov txiaj ntsig - tshwj xeeb tshaj yog txij li NaOH yog hygroscopic heev.
Vim li cas nws thiaj li tsis tsim nyog sau cov burette nrog cov tshuaj alkaline zoo?
Tsis txhob khaws cov tshuaj hauvib lub burette. Cov tshuaj alkaline tej zaum yuav hnov mob nrog lub khob thiab ua rau khov ntawm lub khob stopcock yog li tsis txhob khaws cov tshuaj alkaline hauv ib lub burette. … Yog hais tias cov npuas tawm los thaum ntsuas, nws yuav siv qhov chaw ntawm cov kua dej uas tau sau tseg, tab sis tsis txhob tawm hauv lub burette.
Yuav daws qhov twg hauv burette?
Feem ntau, titrant (cov tshuaj paub)yog ntxiv los ntawm ib lub burette rau ib qho kev paub ntawm cov tshuaj ntsuam xyuas (cov tshuaj thib ob) kom txog thaum cov tshuaj tiv thaiv tiav. Feem ntau, qhov taw qhia qhov muag (tsis yog los yog cov tshuaj pH) yog siv los qhia qhov ua tiav (kawg-point).
Vim li cas koj thiaj yaug lub burette nrog sodium hydroxide thiab tsis distilled dej?
Vim qhov tseeb, tag nrho cov burettes yog ua los ntawm iav, nws tuaj yeem nqus tau thiab nyob twj ywm dej rau ntawm qhov chaw, vim yog lub polarity ntawm iav thiab lub zog intermolecular. … Yog li, koj yuav tsum tau yaug lub burette nrog cov tshuaj uas yuav tsum tau sau rau hauv nws, vim dej distilled hloov qhov concentration ntawm cov tshuaj thawj zaug

Vim li cas cov terranes ntxiv rau cov npoo av av ntau dua li tsis muab tso rau hauv lawv?
Vim li cas cov terranes ntxiv rau cov npoo av sab av loj, ntau dua li subducting hauv qab lawv? Tswv yim dhau buoyant rau subduct. … Cov npoo ntawm ntau lub teb chaws tau loj hlob los ntawm kev tsim cov terranes . Terranes thiab continental kev loj hlob cuam tshuam li cas?
Yuav ua li cas muab tso rau hauv qhov muag tsis muaj cuab yeej?
Ntxiv ib txheej ntawm fusible interfacing rau nyias ntaub ua ntej muab ib lub qhov muag rau nws. Koj tuaj yeem teeb lub qhov muag me me los ntawm kev tso lub qhov muag rau hauv cov ntaub ntawm lub puab tsaig ntawm lub tes tuav tes. Lub nraub qaum ntawm lub qhov muag yuav tsum tau so tawm tsam qhov tuag ntawm lub qhov punch.
Yuav ua li cas sodium hydroxide yaj hauv dej?
Sodium hydroxide, tseem hu ua lye thiab caustic soda, yog ib qho inorganic compound nrog cov mis NaOH. Nws yog ib qho dawb ionic compound uas muaj sodium cations Na⁺ thiab hydroxide anions OH⁻. Yuav ua li cas thaum sodium hydroxide yaj hauv dej?
Rau cov tshuaj tiv thaiv acetic acid nrog sodium hydroxide?
Acetic acid, CH3COOH, yuav hnov mob nrog sodium hydroxide, NaOH, rau tsim sodium acetate, CH3COONa CH3COONa Sodium acetate, NaCH 3 COO, tseem hu ua NaOAc, yog sodium ntsev ntawm acetic acid. Qhov no tsis muaj xim deliquescent ntsev muaj ntau yam kev siv.
