Cov qib pH txiav txim siab qib acidity lossis alkalinity ntawm cov kua. Yog tias koj xav tau kho pH qib ntawm koj cov dej, txawm tias nws yog rau kev tshawb fawb tshawb fawb, ua teb, dej haus, dej thoob dej yug ntses, lossis lwm yam, pib los ntawm kev ntsuas qib pH. Txhawm rau nce lossis txo qis cov kua qaub, ntxiv cov tshuaj alkaline xws li ci dej qab zib. Lub caij no, cov kua qaub hauv dej tuaj yeem nce ntxiv los ntawm kev ntxiv cov kua qaub xws li dej txiv qaub.

Txoj Kev 1 ntawm 3: Kho Cov Qib pH rau Ntses, Nroj Tsuag, Dej Dej, thiab Dej Haus
Kauj Ruam 1. Ntxiv peat mus rau lub thoob dej thoob dej yug ntses kom kho cov pH
Ntses yog rhiab heev rau qib pH ntawm cov dej thiab tuaj yeem tuag yog tias nws yog acidic lossis alkaline. Cov ntses feem ntau muaj sia nyob hauv cov dej nruab nrab, nrog pH ze rau 7. Yog tias cov dej dhau alkaline, ntxiv peat kom qis pH. Yog tias cov kua qaub dhau, ntxiv 5 ml ntawm cov dej qab zib ci rau 20 liv dej kom nce qib pH.
- Nrhiav kom paub cov qib pH xav tau rau hom ntses uas koj muaj los ntawm kev tshawb hauv is taws nem lossis nug lub khw muag tsiaj. Piv txwv li, yog tias koj khaws cov ntses koi, qib pH nyob nruab nrab ntawm 7.5 -8.2.
- Koj tuaj yeem yuav peat ntawm khw muag tsiaj. Muab ib txhais tes ntawm peat tso rau hauv lub hnab ntaub qhwv, thiab muab tso rau hauv lub thoob dej thoob dej yug ntses. Peat yuav txo cov acidity ntawm cov dej nyob rau lub sijhawm.
- Kev hloov pauv sai hauv qib pH tuaj yeem ua rau ntses. Tshem tawm cov ntses los ntawm lub tank ua ntej kho qib pH.
- Ntsuas cov qib pH hauv lub tank ntses ua ntej thiab tom qab hloov kho. Ib qho ntxiv, ua qhov kev sim ua ntej thiab tom qab kho qhov pH ntawm cov dej hauv pas dej lossis dej haus, uas tseem tau tham hauv kab lus no.
Kauj Ruam 2. Hloov pH qib ntawm cov kais dej rau cov nroj tsuag lossis vaj
Feem ntau cov kais dej tsuas tuaj yeem muaj sia nyob ntawm cov kua qaub me ntsis, nrog pH nruab nrab ntawm 5.5 thiab 6.5. Koj tuaj yeem ntxiv cov txiv qaub lossis ntoo tshauv rau 4 liv dej kom nce qib pH. Yog tias koj xav txo qis pH, ntxiv phosphoric acid lossis ntsiav tshuaj tsim los txo qis pH ntawm cov dej.
- Yog tias koj tsis paub pH zoo tagnrho rau tsob ntoo tshwj xeeb, saib hauv online lossis ntawm koj lub chaw zov menyuam. Qee cov nroj tsuag nkag siab txog qib pH thiab xav tau dej ntawm qib pH tseeb. Piv txwv li, dos vam thaum muab dej alkaline nrog pH ntawm 6.5-7.0.
- Txheeb nrog koj lub chaw zov menyuam hauv cheeb tsam kom paub qhov tseeb ntawm tus neeg hloov pauv pH koj xav tau sib xyaw. Koj tseem tuaj yeem yuav txiv qaub, ntoo, ntoo tshauv, thiab phosphoric acid lossis lwm tus neeg txo qis pH ntawm cov chaw zov menyuam.
- Yog tias koj rov ywg dej koj cov nroj tsuag nrog dej nrog pH sab nraum 5.5 - 6.5, lawv yuav yooj yim thiab tuag.
Kauj Ruam 3. Kho qib pH ntawm lub pas dej
Cov pas dej da dej yuav tsum khaws cia ntawm qhov me ntsis alkaline pH, nruab nrab ntawm 7.2 thiab 7.8. Cov qib pH no nce ntxiv ntawm nws tus kheej yog li koj yuav tsum txo qis nws tas li. Cov tuam txhab ua luam dej tsim cov tshuaj lom neeg rau lub hom phiaj no. Qhov ob feem ntau siv tshuaj yog sodium bisulfate thiab hydrochloric/muriatic acid. Ob yam tshuaj no yuav tsum muab sib xyaw ncaj qha rau hauv dej pas dej.
- Yog xav paub cov lus qhia ntxaws ntxiv txog kev nce lossis txo qis pH pas dej da, tham nrog lub chaw tsim khoom lag luam cov lus qhia.
- Koj tuaj yeem yuav sodium bisulfate (tseem hu ua "acid acid") lossis hydrochloric acid ntawm lub khw muag khoom pas dej.
Kauj Ruam 4. Kho cov dej haus yog tias nws muaj kua qaub lossis alkaline
Cov dej haus yuav tsum muaj qib ib txwm, nrog rau pH ntawm qhov tseeb (lossis ze rau) 7. Yog tias qhov ntsuas pom tau tias qib cov dej haus muaj kua qaub lossis alkaline, kho nws kom cov pH nyob nruab nrab. Yog tias cov dej haus muaj kua qaub (pH qis), ntxiv cov tee lossis cov ntsiav tshuaj pH los ua kom cov kua qaub qis. Hloov pauv, yog tias cov dej haus yog alkaline (pH siab), ntxiv ob peb tee dej ntawm txiv qaub, uas yog ib txwm muaj kua qaub.
- Yog tias koj xav kom qib pH hloov pauv mus tas li, teeb tsa cov dej lim dej. Yog tias cov dej yog alkaline, teeb tsa lub lim dej nruab nrab lossis dej qab zib tshauv/sodium hydroxide txhaj tshuaj.
- Yog tias cov dej muaj kua qaub, ntiav ib tus kws tshaj lij los teeb tsa cov kua qaub rau hauv koj lub tsev cov dej.
Txoj Kev 2 ntawm 3: Kuaj Cov Dej pH Hauv Tsev
Kauj Ruam 1. Ntxiv 5 ml ntawm ci dej qab zib rau 230 grams khob dej
Cov dej qab zib ci yog alkaline, nrog rau qib pH ntawm 9. Ntxiv 5 ml ntawm cov dej qab zib ci rau ib khob dej thiab sib tov nrog rab diav lossis lwm yam kev sib tov. Khaws kom txog thaum tag nrho cov ci dej qab zib yog yaj tag. Tom qab ntawd, ntsuas pH qib ntawm cov dej dua siv daim kab xev.
Yog tias koj pib nrog dej nruab nrab (pH 7), pH yuav nce mus txog 8
Kauj Ruam 2. Ntxiv 1 teaspoon (5 ml) kua txiv qaub rau hauv ib khob dej
Sib tov ob lub kua nrog ib rab diav. Tos li ob peb feeb, thiab saib seb pH ntawm cov dej tau hloov pauv li cas.
Txij li cov kua txiv qaub yog kua qaub, nrog rau tus nqi pH ntawm 2, pH qib ntawm cov dej hauv iav yuav txo mus rau 6 lossis 5
Kauj Ruam 3. Kuaj nrog cov hauv paus sib txawv thiab lwm yam kua qaub
Muaj ntau yam kua thiab sib tov muaj nyob hauv tsev thiab hloov pauv pH ntawm cov dej. Dissolve los yog sib tov cov tshuaj me me ntawm ib lub sij hawm hauv ib khob dej huv, tom qab ntawd sim siv cov kab litmus. Yog tias koj tab tom sim tshawb fawb, tsim cov khoom siv los teev cov qib pH ntawm cov dej sib xyaw nrog ntau yam khoom xyaw, txhua qhov hauv ib khob dej cais. Sim ntxiv:
- Coca-Cola.
- Liab caw.
- Mis.
- Cov xab npum los yog zawv plaub hau.
Txoj Kev 3 ntawm 3: Ntsuas pH ntawm Dej nrog Kev Xeem Sawb
Kauj Ruam 1. Yuav cov dej ntsuas pH
Ib daim ntawv xeem pH, tseem hu ua daim kab xev, yog ib daim ntawv me me 5 cm ntev thiab 1.5 cm dav. Daim ntawv no tau lo nrog cov tshuaj lom neeg uas hloov xim thaum kis rau tib yam khoom lossis hauv paus. Cov ntawv ntsuas pH no tuaj yeem yuav tau ntawm cov chaw muag tshuaj lossis cov khw muag khoom kuaj sim.
Koj tseem tuaj yeem yuav cov kab ntawv pH ntawm cov khw muag khoom online loj, lossis khw muag tsiaj
Kauj Ruam 2. Dip 1 pH sawb rau hauv cov dej piv rau 10 vib nas this
Ntxiv 2.5 cm ntawm pH sawb rau hauv dej. Dip ob sab; tag nrho cov hlua yog pH rhiab heev. Nco ntsoov tuav ib kawg ntawm kab txaij kom nws thiaj li tsis xoob thaum kuaj cov kua qaub lossis alkalinity ntawm cov dej.
- Piv txwv li, muab cov dej haus tso rau hauv khob yog tias koj xav sim ntsuas pH qib ntawm cov dej haus.
- Yog tias koj xav sim kho cov pH ntawm koj lub tank dej cov dej, nqes ib txoj kab ntsuas pH mus rau hauv dej los ntawm sab saum toj ntawm lub tank los ntsuas nws.
- Koj tseem tuaj yeem siv lub raj xa dej los tso 1-2 tee dej ntawm cov ntawv sim rau hauv daim ntawv txiv qaub.
Kauj Ruam 3. Pom qhov kev hloov xim ntawm daim ntawv txiv qaub
Tom qab pH kab txaij tau raug dej rau 10 vib nas this, saib cov xim hloov pauv. Cov xim ntawm kab txaij yuav qhia txog qhov acidity lossis alkalinity ntawm cov dej.
Yog tias kab txaij tsis hloov xim tam sim ntawd, tos ob peb feeb
Kauj Ruam 4. Sib piv cov kab xev pH nrog qhov ntsuas xim pH
Cov khoom ntsuas pH yuav tsum muaj daim duab xim. Kab ntawv no qhia cov xim ntawm daim ntawv litmus thaum raug rau cov kua qaub lossis cov hauv paus. Sib phim cov xim ntawm pH kab rau cov xim ntawm kab ntawv, thiab koj yuav paub pH qib ntawm cov dej.
Feem ntau, yog tias kab txaij litmus liab, nws txhais tau tias cov dej muaj acidic heev. Yog tias xim yog xim daj, dej yog acidic nruab nrab, ntsuab txhais tau tias alkaline nruab nrab, thiab ntshav liab txhais tau tias alkaline heev
Kauj Ruam 5. Ntsuas qib pH siv tus nyeem ntawv digital kom tau txais txiaj ntsig zoo dua
Litmus cov kab ntawv tau nrawm nrawm thiab muaj txiaj ntsig ntawm ntsuas pH qib, tab sis muaj ntau txoj hauv kev muaj dua. Tus nyeem ntawv digital (feem ntau hu ua "pH meter") yog lub cuab yeej muaj tseeb ntau dua, tuaj yeem txiav txim siab qib pH mus rau 2 qhov chaw. Qhov ua kom yuam kev, poob qhov taub ntawm lub ntsuas pH mus rau hauv dej kom txog thaum lub vijtsam qhia pom qhov tshwm sim.
- Cov ntsuas pH feem ntau siv hauv cov chaw tshawb fawb tshawb fawb thiab tuaj yeem yuav lossis xaum hauv khw muag khoom kuaj.
- Tus ntsuas pH yuav tsum tau rov ntsuas dua ntawm txhua qhov kev siv. Ua raws cov lus qhia teev tseg nrog lub ntsuas ntsuas pH kom tau txais txiaj ntsig zoo tshaj plaws.
