Qhov ntsuas pH ntsuas yuav ua li cas cov tshuaj yuav tsum tso protons (lossis H+ ions) thiab yuav ua li cas cov khoom ntawd yog lees txais cov protons. Ntau cov lwg me me, suav nrog cov zas xim, yuav hloov lawv cov qauv los ntawm kev lees txais cov tshuaj protons los ntawm ib puag ncig acidic (ib qho uas npaj tau muab cov tshuaj protons) lossis pub cov tshuaj protons rau ib puag ncig yooj yim (ib qho uas yooj yim lees txais protons). Kev ntsuas rau pH yog qhov tseem ceeb ntawm ntau yam kev sim tshuaj lom neeg thiab lom neeg. Qhov kev ntsuas no tuaj yeem ua tiav los ntawm txheej txheej kab ntawv nrog cov zas xim uas yuav hloov pauv mus rau xim sib txawv thaum muaj cov kua qaub lossis lub hauv paus.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Ua Cov Ntawv Hauv Tsev pH nrog Cabbage
Kauj Ruam 1. Txiav qee cov zaub liab
Koj yuav tsum tau txiav txog ¼ ntawm lub taub hau ntawm liab zaub qhwv thiab muab tso rau hauv rab. Koj yuav rho cov tshuaj los ntawm cov zaub qhwv los npog koj daim ntawv pH. Cov tshuaj no paub tias yog anthocyanins thiab muaj nyob hauv cov nroj tsuag xws li zaub qhwv, paj tawg, thiab txiv hmab txiv ntoo. Anthocyanins yog xim liab nyob hauv nruab nrab cov xwm txheej (pH 7.0) tab sis lawv hloov xim thaum raug rau cov kua qaub (pH 7.0).
- Tib txoj hauv kev tuaj yeem ua raws siv cov txiv ntoo, paj paj, thiab lwm yam anthocyanin uas muaj cov nroj tsuag.
- Qhov no tsis ua haujlwm rau zaub ntsuab. Tib yam anthocyanins tsis muaj nyob hauv zaub ntsuab.
Kauj Ruam 2. Ntxiv dej npau rau koj cov zaub qhwv
Koj tuaj yeem rhaub dej rau ntawm lub qhov cub lossis hauv microwave, tab sis ob txoj hauv kev koj yuav xav tau txog 500 ml dej. Ncuav cov dej npau ncaj qha mus rau hauv rab nrog cov zaub qhwv. Qhov no yuav pab kos cov tshuaj xav tau tawm ntawm cov zaub qhwv.
Kauj Ruam 3. Qhib lub tshuab ziab khaub ncaws
Koj yuav tsum muab cov dej thiab zaub qhwv rau qhov ua tau zoo tshaj plaws. Khaws qhov sib tov sib xyaw kom txog thaum cov dej tsaus nti. Qhov kev hloov xim no qhia tias koj tau ua tiav qhov xav tau cov tshuaj (anthocyanins) los ntawm cov zaub qhwv thiab yaj lawv rau hauv dej kub. Koj yuav tsum tso cov ntsiab lus ntawm lub tshuab ziab kom txias tsawg kawg kaum feeb ua ntej yuav mus.
Kauj Ruam 4. Ncuav qhov sib tov hla lub lim
Koj xav tshem tawm ib daim ntawm cov zaub qhwv los ntawm qhov ntsuas daws (dej xim). Cov ntawv lim dej yuav ua haujlwm ntawm tus neeg lim dej, tab sis yuav siv sijhawm ntau dua. Thaum koj tau lim qhov ntsuas kev daws teeb meem, koj tuaj yeem muab cov zaub qhwv pov tseg.
Kauj Ruam 5. Ntxiv isopropyl cawv rau koj qhov kev ntsuas ntsuas
Ntxiv txog 50 mL ntawm isopropyl cawv yuav tiv thaiv koj cov tshuaj los ntawm cov kab mob loj hlob. Cov cawv tuaj yeem pib hloov xim ntawm koj cov tshuaj. Yog tias qhov no tshwm sim, ntxiv vinegar kom txog thaum daws tau rov qab mus rau qhov tsaus ntuj.
Koj tuaj yeem hloov ethanol rau cawv isopropyl, yog tias tsim nyog lossis xav tau
Kauj Ruam 6. Ncuav cov tshuaj tov rau hauv lub lauj kaub lossis lub tais
Koj xav tau lub ntim uas muaj qhov qhib dav txaus los qhwv koj daim ntawv. Koj yuav tsum xaiv lub thawv uas tsis muaj qhov tsis kam tiv taus, zoo li koj tau nchuav cov xim rau hauv. Tej hub thiab iav yog cov kev xaiv zoo.
Kauj Ruam 7. Tsau koj daim ntawv hauv qhov ntsuas ntsuas
Nco ntsoov thawb daim ntawv mus rau hauv qab. Koj xav npog tag nrho cov ces kaum thiab cov npoo ntawm daim ntawv. Nws yog lub tswv yim zoo los siv hnab looj tes rau theem no.
Kauj Ruam 8. Tso koj daim ntawv kom qhuav ntawm daim phuam
Nrhiav qhov chaw uas tsis muaj acidic lossis yooj yim vapors. Daim ntawv yuav tsum tau tso cai kom qhuav tag ua ntej mus. Qhov zoo tshaj, koj yuav tso nws tseg ib hmos.
Kauj Ruam 9. Txiav daim ntawv ua tej daim
Qhov no yuav tso cai rau koj sim ntau qhov piv txwv sib txawv. Koj tuaj yeem txiav cov kab ntawv me me uas koj xav tau, tab sis feem ntau qhov ntev thiab dav ntawm koj tus ntiv tes ntsuas yog qhov zoo. Qhov no yuav tso cai rau koj nqes kab txaij rau hauv tus qauv yam tsis tau muab koj cov ntiv tes rau hauv cov qauv.
Kauj Ruam 10. Siv daim kab xev los ntsuas pH ntawm cov kev daws teeb meem sib txawv
Koj tuaj yeem sim tshuaj hauv tsev xws li kua txiv kab ntxwv, dej, thiab mis. Koj tseem tuaj yeem sib xyaw cov kev daws teeb meem rau kev sim, piv txwv. sib tov dej thiab ci dej qab zib. Qhov no yuav muab ntau yam qauv rau koj sim.
Kauj Ruam 11. Khaws cov kab txaij tso rau qhov chaw txias
Koj yuav tsum siv lub thawv ntim cua kom khaws cov kab xev kom txog thaum koj siv lawv. Qhov no yuav tiv thaiv lawv los ntawm ib puag ncig kev kis kab mob xws li kua qaub los yog cov pa roj av yooj yim. Nws tseem yog qhov zoo tshaj plaws kom tsis txhob tso lawv ncaj qha tshav ntuj, vim qhov no tuaj yeem ua rau cov tshuaj dawb dhau sijhawm.
Txoj Kev 2 ntawm 2: Ua Ntawv Hauv Tsev Litmus
Kauj Ruam 1. Tau txais cov hmoov qhuav litmus
Litmus yog cov sib txuas uas tau txais los ntawm lichens, fungi uas tsim kev sib raug zoo nrog alga thiab/lossis cyanobacteria uas muaj peev xwm ua hluav taws xob. Koj tuaj yeem yuav litmus hmoov online lossis hauv khw muag tshuaj lom neeg.
Nws tuaj yeem ua rau koj tus kheej litmus hmoov yog tias koj yog tus kws tshaj lij kws muaj peev xwm. Txawm li cas los xij, cov txheej txheem muaj feem cuam tshuam thiab suav nrog ntxiv ntau qhov sib xyaw xws li txiv qaub thiab potash rau hauv av lichens thiab tso cai rau lub lis piam rau fermentation
Kauj Ruam 2. Dhuav cov litmus rau hauv dej
Nco ntsoov do cov tshuaj thiab cua sov yog tias hmoov tsis yaj zoo. Cov hmoov litmus yuav tsum tau yaj tag rau hauv dej. Qhov kev daws teeb meem yuav tsum yog xim violet-xiav.
Kauj Ruam 3. Muab cov ntawv dawb uas tsis muaj kua qaub tso rau hauv cov kua litmus
Tau txais txhua sab thiab kaum ntawm daim ntawv ntub nrog cov tshuaj. Qhov no yuav muab rau koj thaj chaw zoo tshaj plaws ntawm kab ntawv xeem thiab muab cov txiaj ntsig tau raug tshaj plaws. Koj tsis tas yuav tawm ntawm daim ntawv mus rau "tsau" tsuav koj ua kom ntseeg tau tias nws tau pleev xim zoo.
Kauj Ruam 4. Tso koj daim ntawv kom qhuav
Koj yuav tsum tau qhuav daim ntawv hauv qhov cua qhib, tab sis nco ntsoov tias koj tsis nthuav tawm nws mus rau cov kua qaub lossis cov pa tsw qab. Cov pa no tuaj yeem kis kab mob thiab ua rau tsis raug. Koj kuj yuav tsum nco ntsoov khaws lawv hauv qhov chaw qhuav, tsaus ntuj kom tiv thaiv kev kis kab mob thiab tshuaj dawb.
Kauj Ruam 5. Siv daim ntawv litmus los ntsuas qhov acidity
Cov ntawv xiav litmus tig liab thaum muaj cov kua qaub. Nco ntsoov tias lawv yuav tsis qhia tias cov kua qaub muaj zog npaum li cas, lossis seb qhov kev daws teeb meem yog qhov yooj yim. Tsis hloov pauv txhais tau tias kev daws teeb meem yog qhov yooj yim lossis nruab nrab, tab sis tsis yog acidic.
Koj tuaj yeem ua daim ntawv litmus liab (uas tig xiav thaum raug rau lub hauv paus) los ntawm kev ntxiv cov kua qaub rau qhov ntsuas ntsuas ua ntej tsau koj daim ntawv
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
- Siv tsuas yog dej lim lossis dej huv.
- Koj tuaj yeem siv Universal Qhov Ntsuas los sib piv rau kev nyeem ntawm kab ntawv ua nrog tib qhov ntsuas ntsuas. Qhov no yuav muab tswv yim rau koj lub zog ntawm kev nyeem ntawv.
- Koj tuaj yeem txiav daim ntawv ua ib kab ua ntej lossis tom qab muab nws tso rau hauv qhov ntsuas qhov ntsuas. Tsis txhob sim txiav daim ntawv thaum nws ntub.
Lus ceeb toom
- Khaws cov ntawv npaj rau hauv qhov chaw txias, tsaus, qhuav hauv lub thawv cua.
- Kov cov ntawv xeem nrog txhais tes qhuav xwb.
- Ua txhua yam kua qaub nrog kev saib xyuas zoo thiab nyob hauv kev saib xyuas ntawm tus neeg muaj lub luag haujlwm, xws li kws qhia txuj ci yog tias koj tab tom ua chav kawm. Hnav cov iav kom tsim nyog los tuav ib qho ntawm cov tshuaj.
