Yuav ntsuas pH pas dej li cas, ntau npaum li cas thiab hom meters

En Ok Pauv Reform, nyob rau hauv nqe lus no nyob rau hauv lub pH theem pas ua luam dej peb yuav kho cov Yuav ntsuas pH pas dej li cas, ntau npaum li cas thiab hom meters.

Yuav ntsuas pH tus nqi li cas

Vim li cas peb thiaj ntsuas pH?

Vim li cas peb tuaj yeem ntsuas tus nqi pH

• Ntawm qhov tod tes, qhia meej tias pH (acids thiab alkaline bases) muaj cov yam ntxwv uas tso cai rau lawv ntsuas: Qhov concentration ntawm hydrogen ions.

Yuav ntsuas pH li cas?

Kev ntsuas ntawm pH ntawm ib yam khoom tuaj yeem ua tsaug rau ntau txoj hauv kev:

Kev ntsuas pH:

1. Ua ntej ntawm tag nrho cov, feem ntau txoj kev yog a pH 'meter', uas suav nrog pH-sensitive electrode (feem ntau yog ua los ntawm iav) thiab siv electrode.
2. Hauv qhov chaw thib ob, muaj acid-base ntsuas hloov xim nyob rau hauv teb rau txawv pH nqi. Daim ntawv litmus thiab pH ntawv yog siv rau kev ntsuas ceev thiab tsis raug. Cov no yog cov strips ntawm daim ntawv uas tau kho nrog qhov ntsuas.
3. Koj tuaj yeem siv a colorimeter ntsuas pH ntawm ib qho qauv. Ib lub vial tau ntim nrog cov qauv thiab ib qho reagent ntxiv los tsim cov xim hloov pH. Cov xim yog muab piv rau ib daim duab los yog qauv los txiav txim tus nqi pH.
4. Ib yam li ntawd, muaj cov txheej txheem hlau electrode (xws li txoj kev hydrogen electrode, quinhydron electrode method, thiab antimony electrode method)
5. Cov txheej txheem iav electrode
6. Thiab thaum kawg tus Cov txheej txheem semiconductor sensor.

Phenolphthalein ntsuas ntsuas pH tus nqi

phenolphthalein formula

La phenolphthalein, ntawm formula C₂₀H₁₄O₄, yog qhov ntsuas pH uas tseem tsis muaj xim hauv cov kua qaub, tab sis hauv cov kev daws teeb meem yooj yim nws hloov xim liab nrog qhov hloov pauv ntawm pH = 8,2 (tsis muaj xim) thiab pH = 10 (magenta lossis liab).

Dab tsi yog qhov taw qhia los ntsuas ph nqi ntawm phenolphthalein

PHENOLPHTHALEIN yog Acid-Base qhia tau dav siv hauv Volumetrics. Qee qhov dav dav ntawm qhov ntsuas no tau piav qhia hauv qab no.

• Indicators: Methyl Liab, Thymol Blue
• Melting point: 531K (258 ° C)
• Cov mis mos ib nrab tsim: C20H14O4
• Cov qauv zoo sib xws: Thymolphthalein, Triphenylmethane

phenolphthalein pH qhia tau npaj li cas?

Tswj pH ntawm lub pas dej

Yuav tswj cov pH ntawm lub pas dej da dej li cas?

Thawj qhov uas koj yuav tsum tau mus txog qhov nruab nrab pH theem hauv pas dej da dej yuav yog ib lub meter txhim khu kev qha uas, ntxiv rau qhov tso cai rau koj ntsuas qhov ntsuas no, muab kev xaiv rau koj paub txog qib ntawm chlorine. Hmoov zoo, muaj ntau yam khoom siv hauv khw los ua txoj haujlwm no. Thaum koj tau ua qhov ntsuas pH ntawm cov dej, koj tuaj yeem ntsuas qhov tsim nyog seb cov dej puas yog acidic lossis alkaline.

Yog tias lub pas dej pH siab, piv txwv li saum toj no 7,6, lub pas dej yog suav tias yog alkaline. Txhawm rau kho qhov teeb meem thiab kho qhov nruab nrab ntawm cov dej, nws yuav tsum tau siv lub pH reducer. Nco ntsoov tias thaum pH siab dhau lawm, cov tshuaj chlorine tsis muaj kev cuam tshuam hauv dej thiab cov tsos mob ntawm cov kab mob thiab cov algae tau yooj yim. Vim li ntawd, ua ntej ntxiv txhua yam tshuaj rau lub pas dej, xyuas kom meej tias pH yog nruab nrab.

Tswj ntsuas ntsuas pH raug

Cov lus qhia kom tswj hwm tus nqi pH zoo tagnrho

Tsis tu ncua xyuas pH ntawm lub pas dej ua ke: yog tias ua tau txhua 3-4 hnub.

Thaum muaj qhov tsis zoo ib ntus: xyuas pH ntawmdej Tsuas yog tom qab.

Ua ntej tshaj plaws, txhawm rau tswj pH ntawm lub pas dej thiab xyuas kom meej tias nws cov dej haum rau kev da dej, nws yog ib qho tsim nyog los ntsuas pH qib ntawm cov dej..

Ib zaug ntxiv, peb qhia koj tias qhov zoo tshaj pH tus nqi ntawm cov dej yog: 7,2-7,6.

Yog li ntawd, peb yuav muaj pH ntawm 7,2 thiab 7,6, uas tso cai rau peb kom tsis txhob ntxiv tshuaj ntxiv rau cov dej.

Thiab, peb yuav khaws cov dej hauv pas dej kom zoo thiab muaj cov dej huv thiab cov dej ntshiab huv los saib xyuas txhua tus neeg txoj kev noj qab haus huv.

Acid lossis alkaline pH qhov tseem ceeb hauv pas dej da dej

Nov yog qee qhov kev ntsuas kom paub txog acidity lossis alkalinity ntawm cov dej hauv pas dej:

• Hauv cov pas dej da dej, acidic pH nyob ntawm 0 txog 7,2.
• Cov dej distilled muaj pH = 7, uas yog, tus nqi uas nyob nruab nrab lossis nruab nrab. Txawm hais tias nyob rau hauv cov ntaub ntawv ntawm lub pas dej nws yuav yog ib tug tsawg pH.
• tus nqi pH dej zoo: 7,2
• Qhov tseeb pH qhov tseem ceeb: ntawm 7,2-7,6.
• Thaum kawg, hauv cov pas dej da dej, pH qhov tseem ceeb nyob nruab nrab ntawm 7,2-14.

Yuav ntsuas li cas yog pH yog acid los yog puag

Txhawm rau paub yog tias pH ntawm lub pas dej yog kua qaub lossis tsis muaj zog peb siv cov ntsuas thiab ntsuas xws li phau ntawv los yog digital (automated).

Lwm qhov tseem ceeb tsis muaj feem cuam tshuam rau lub pas dej pH

• Xyuas kom tseeb tias cov tshuaj chlorine nyob rau theem tsim nyog.
• Tus nqi chlorine dawb ntawm 0,5 - 2,0 mg / l uas tiv thaiv kev tsim ntawm chloroquine thiab nws cov ntxhiab tsw.
• Ua ke cov tshuaj chlorine tsawg dua 0,6 mg / l uas tua kab mob thiab tiv thaiv kev kub nyhiab.
• Thiab tag nrho cov tshuaj chlorine tsim los ntawm ob yav dhau los qhov siab tshaj plaws ntawm 2,6 mg / l.
• Hais txog seb koj puas siv lwm txoj kev sib txawv ntawm kev tua kab mob hauv pas dej ua ke dua li cov tshuaj chlorine (bromine, oxygen, thiab lwm yam), xyuas lawv cov txiaj ntsig.
• Tag nrho Alkalinity: yuav tsum tau teem caij ntawm 125 thiab 150 ppm.
• Cov dej hauv pas dej tau tsim nyog: ntawm 25 txog 30ºC

Yuav tswj cov pH ntawm lub pas dej li cas

li cas pH Cov xwm txheej koj tuaj yeem ntsib yog cov hauv qab no

siab pH pas dej

• pH yog siab dua 7.6. Cov dej hauv pas dej ua ke, feem ntau, los tsa pH qhov tseem ceeb.
• Nrog rau pH siab, cov dej hauv pas dej ua rau huab, cov tshuaj chlorine nres muaj kev cuam tshuam rau cov dej thiab cov tsos mob ntawm cov kab mob thiab cov algae tau yooj yim.
• Vim li ntawd, ua ntej ntxiv txhua yam tshuaj rau lub pas dej, xyuas kom meej tias pH yog nruab nrab. chlorine poob nws cov tshuaj tua kab mob thiab tsim chloramines nrog cov organic teeb meem, ua rau khaus ntawm lub qhov muag thiab mucous daim nyias nyias, nrog rau cov yam ntxwv tsw uas cov dej muab tawm.
• Kev daws yog siv lub pH reducer, uas yog nyob rau hauv cov kua los yog granulated nthuav qhia. Siv milliliters lossis grams ib cubic meter dej raws li kev pom zoo los ntawm cov chaw tsim khoom kom txo qis pH los ntawm 0.1.
• Yog tias lub pas dej pH siab, piv txwv li saum toj no 7,6, lub pas dej yog suav tias yog alkaline. Txhawm rau kho qhov teeb meem thiab rov ua kom nruab nrab ntawm cov dej, nws yuav tsum tau siv lub pH reducer.

Tsawg pH dej hauv pas dej.

• pH yog qis dua 7.2. Cov txheej txheem koj yuav tsum ua raws yog tib yam li hauv rooj plaub dhau los, tab sis siv pH raiser. Curiously, chlorine ua haujlwm 100% nrog pH sib npaug rau 5, tab sis nws yuav ua tsis tau rau chav dej.
• Yog tias pH ntawm koj lub pas dej yog acidic, uas yog, nws tsawg dua 7,2, nws yuav yog qhov tseem ceeb uas yuav tsum tau siv qhov nce ntxiv. Rau cov xwm txheej no, cov kws tshaj lij pom zoo kom siv cov dej qab zib caustic, tshuaj lom neeg paub txog nws cov alkalinity. Lub pH ntawm caustic soda Nws yog qhov yooj yim heev thiab tuaj yeem pab tswj cov acidity ntawm cov dej. Qhov no, qhov tseeb, ib qho ntawm nws feem ntau siv nyob rau hauv kev ua lag luam. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias nws yog cov khoom corrosive uas tsis tuaj yeem siv siab dua 100 grams ib 10m3 dej. Ib yam li ntawd, nws yuav tsum tau ntxiv tag nrho diluted raws li cov chaw tsim khoom cov lus qhia thiab ib txwm
