kusiyana pakati pa ph ndi poh

Mlozera wa zomwe zili patsamba

En Ok Pool Kusintha, mu gawo ili mkati mwa Maiwe osambira a pH level tidzawachitira kusiyana pakati pa ph ndi poh m'madzi amadzimadzi.

Kodi pH mu dziwe ndi chiyani ndipo milingo yake iyenera kukhala bwanji?

Kodi pH ya dziwe ndi chiyani komanso momwe mungakulitsire

Patsamba lino mutha kuphunzira za Pool pH Level: ndi mlingo wotani wa pH wa dziwe, zotheka zake, njira zoyezera, kusintha ndikuwongolera. Kodi pH ndi chiyani: Coefficient yomwe imawonetsa kuchuluka kwa acidity kapena maziko amadzi. Chifukwa chake, pH imayang'anira kuwonetsa kuchuluka kwa ma H + ma ion m'madzi, kudziwa mtundu wake wa acidic kapena woyambira.

Kodi pH yabwino imatanthawuza chiyani pamadzi osambira (7,2-7,4)

Mawu akuti pH amaimira kuthekera kwa haidrojeni ndipo ndi muyeso womwe umasonyeza acidity kapena maziko a madzi.

Kotero, pH imatanthawuza kuthekera kwa haidrojeni, mtengo womwe umafanana ndi kuchuluka kwa ayoni wa haidrojeni m'madzi mu dziwe lanu ndipo ndiye coefficient yomwe ikuwonetsa kuchuluka kwa acidity kapena maziko amadzi. Chifukwa chake, pH imayang'anira kuwonetsa kuchuluka kwa ma H + ma ion m'madzi, kudziwa mawonekedwe ake acidic kapena oyambira.

Kuchuluka kwa pH yamadzi osambira

Kodi mulingo wa pH wa madzi amadzimadzi umaphatikizapo zinthu ziti?

Mulingo wa pH umaphatikizapo miyeso kuyambira 0 mpaka 14.
Makamaka kukhala 0 wa acidic kwambiri, 14 wofunikira kwambiri ndikuyika Neutral pH pa 7.
Kuyeza uku kumatsimikiziridwa ndi kuchuluka kwa ma ayoni a haidrojeni (H+) m'chinthucho.

Chifukwa chiyani timafunikira pH?

pH ndi muyeso womwe umagwiritsidwa ntchito pofotokoza acidity kapena maziko a yankho lamadzi. Kaya njira yamadzimadzi imagwira ntchito ngati asidi kapena maziko zimatengera zomwe zili mu ayoni wa haidrojeni (H+).

Komabe, ngakhale madzi oyera komanso osalowerera ndale amakhala ndi ma hydrogen ions chifukwa chodzipatula pamadzi.

$H_2O \utali kumanzere kumanja H^+ + OH^-$

Zimadziwika kuti pamlingo wokhazikika (750 mmHg ndi 25 ° C), 1 L yamadzi oyera imakhala ndi $10^{-7}$ mol $H^+$ y $10^{-7}$ mol $O^-$ ions, motero, madzi pa kutentha kwapakati ndi kuthamanga (STP) ali ndi pH ya 7.

Zoyenera kuchita ngati pH ya dziwe lathu SIKUYANGIDWA

Dziwani zotsatira za pH dziwe lapamwamba komanso zomwe zimayambitsa pH yayikulu padziwe lanu

Mu blog iyi timalankhula za pH yamadzi ambiri, zotsatira zake ndi zomwe zimayambitsa kusalinganika. Kodi pH ya maiwe oyambira kapena dziwe la alkaline ndi chiyani: Ngati ma ion a Hydroxide ndi ochulukirapo kuposa ma ayoni a Hydrogen, pH imatchedwa Basic OH-> H+. Choncho, ngati pH ili yaikulu kuposa 7,4, madzi amati ndi ofunika ndipo pH ya madzi a dziwe imatchedwa alkaline. Phunziraninso momwe mungachepetsere pH yamchere ya dziwe komanso zomwe zimachitika ndikakhala ndi pH yapamwamba padziwe.

Momwe mungakwezere pH ya dziwe komanso zomwe zimachitika ngati ili yotsika

Momwe mungakwezere PH ya dziwe: Kuti musunge madzi abwino komanso ma pH oyenera, izi ziyenera kukhala pakati pa 7,2 ndi 7,6. Phunzirani momwe mungakwezere pH ya dziwe ndikudziwa zotsatira za zomwe zimachitika ngati pH ya dziwe ili yochepa.

Momwe Mungatsitsire Dziwe Lapamwamba kapena Lamchere pH

Momwe mungatsitsire PH ya dziwe: Kuti madzi azikhala abwino komanso pH yoyenera, izi ziyenera kukhala pakati pa 7,2 ndi 7,6. Phunzirani momwe mungachepetse pH ya dziwe ndikudziwa zotsatira za zomwe zimachitika ngati dziwe pH lili pamwamba.

Maupangiri amomwe mungasamalire dziwe kuwonjezera pa pH: kuyeretsa madzi ndi kupha tizilombo toyambitsa matenda

Kalozera wothandiza kudziwa kuyeretsa dziwe

Phuli loyera: upangiri wamitundu yonse ndi machenjezo limodzi ndi chiwongolero chokhazikitsa ndi kukonza mwachizolowezi.

Kalozera pakusamalira dziwe lomwe lili ndi madzi mumkhalidwe wabwino

Patsambali tikufotokoza zonse zokhudzana ndi kukonza ma dziwe nthawi zonse: kuthira tizilombo toyambitsa matenda m'madzi, kusefera m'madzi, kuyeretsa m'madziwe ndi kukonza ma pool liner.

Acidic, neutral ndi alkaline pH values

Kodi acidic ndi pH yoyambira imatanthauza chiyani?

Acid ndi pH yoyambira: Dziwani zikhulupiriro ndi tanthauzo lakupeza mtengo umodzi kapena wina kutengera yankho (makamaka makamaka pa maiwe osambira).

Kuyika kwa Scale ya pH Values

Kodi pH values ndi chiyani

ph pisci6 ndi chiyani

Mulingo wa pH umachokera ku 1 mpaka 14, pH 7 kukhala yankho losalowerera ndale.

Chifukwa chake, zikuwoneka kuti pH ndi mtengo womwe umawonetsedwa pamlingo wa logarithmic pakati pa 0 (yambiri acidic) ndi 14 (zamchere kwambiri); Pakatikati timapeza mtengo wa 7 wotchulidwa ngati wosalowerera.

pH scale universal pH chizindikiro

Kodi zikutanthawuza chiyani kuti chinthu chili ndi acidic kapena alkaline pH level?

Kodi ma acid ndi maziko ndi chiyani?

Acids ndi maziko ndi zinthu zomwe zilipo m'chilengedwe ndipo zimasiyanitsidwa ndi pH yawo, ndiye kuti, ndi kuchuluka kwa acidity kapena alkalinity. Kudziwa ngati zinthu zili acidic kapena zamchere zimayenderana ndi kuchuluka kwa acidity kapena zamchere zomwe zimayezedwa kudzera mu sikelo ya pH ndipo zimayambira pa 0 (zokhala acidic kwambiri mpaka 14 (zamchere kwambiri). komabe ali ndi ntchito zambiri zamafakitale ndi anthu.

Kodi zinthu za acidic ndi chiyani?

Acid pH mlingo: pH zosakwana 7

Kodi pH imatanthauza chiyani ndi acidic?

Kuti chinthu ndi acidic zikutanthauza kuti ili ndi H⁺ (ma hydrogen ions): pH wamkulu kuposa 7
Chifukwa chake, Acids ndi zinthu zomwe zili ndi pH zosakwana 7. (pH yamadzi yofanana ndi 7, yomwe imatengedwa kuti salowerera ndale), yomwe chemistry yake imakhala ndi ayoni ambiri a haidrojeni powonjezera madzi. Nthawi zambiri amakumana ndi zinthu zina potaya ma protoni (H⁺).

Kodi zinthu zopanda ndale ndi chiyani?

Phindu losalowerera ndale: pH yofanana ndi 7-

Kodi pH imatanthauza chiyani?

PH ndi muyeso wa momwe madzi aliri acidic / maziko ake.
Mtunduwu umachokera ku 0 mpaka 14, ndipo 7 salowerera ndale.

Kodi zinthu zamchere ndi chiyani?

Zinthu zomwe zili ndi maziko kapena zamchere pH: pH yoposa 7.

Kodi pH imatanthauza chiyani pamene mtengo uli wamchere?

Kuti chinthu ndi alkaline zikutanthauza kuti ndi osauka H⁺ (kapena olemera mu OH maziko^-, zomwe zimapangitsa kuti H⁺).
Mwa zonsezi, Maziko, kumbali ina, ndi zinthu zomwe zili ndi pH yoposa 7., omwe m'madzi amadzimadzi nthawi zambiri amapereka ma hydroxyl ions (OH^-) pakati. Amakonda kukhala oxidants amphamvu, ndiko kuti, amachitira ndi ma protoni ochokera kumadera ozungulira.

Kusiyana pakati pa pH ndi pOH

ph value sikelo formula

Kodi zimagwirizana bwanji ndipo pali kusiyana kotani pakati pa miyeso ya ph ndi poh?

kusiyana pakati pa miyeso ya ph ndi poh

Zachidziwikire, ntchito ya ma ion imadalira kuchuluka kwa ion ndipo izi zikufotokozedwa mu equation

pH / poH ion ntchito equation

$a_{H^+}=f \cdot [H^+]$
kuti,
$ndi_{H^+}$ - hydrogen ion ntchito
$f$ - coefficient ntchito ya ayoni wa haidrojeni
$[H^+]$ - hydrogen ion ndende

Coefficient ya ntchito ndi ntchito ya ndende ya ion ndipo imayandikira 1 pamene yankho likuwonjezereka kwambiri.

Kuti muchepetse (zabwino) mayankho, muyezo wa solute ndi 1,00 M, ndiye kuti kuchuluka kwake kumafanana ndi ntchito yake.

Chifukwa chake, pamavuto ambiri omwe amakhala ndi mayankho abwino, titha kugwiritsa ntchito logarithm ku maziko 10 a ndende ya molar, osati zochitikazo.

Kusiyana pakati pa mtengo wa pH ndi pOH

ph ndi poh value scale

Kodi pH yabwinobwino ndi iti?

Mwanjira ina, pH ndi muyeso womwewo amagwiritsidwa ntchito kukhazikitsa mulingo wa acidity kapena alkalinity ya yankho. "P" imayimira "kuthekera", ndichifukwa chake pH imatchedwa: kuthekera kwa haidrojeni.

Kodi mtengo wa pOH ndi chiyani?

Kwa inu. pOH ndi muyeso wa kuchuluka kwa ayoni a hydroxyl mu yankho. Imawonetsedwa ngati maziko a 10 negative logarithm ya hydroxyl ion concentration ndipo, mosiyana ndi pH, imagwiritsidwa ntchito kuyeza mulingo wa alkalinity wa yankho.

werengera mtengo wa ph

Kodi pH kapena pOH imawerengedwa bwanji?

Kodi njira yopangira masikelo a ph ndi yotani?

Monga momwe zimadziwika kale, m'munda wasayansi, ndi pH ndiye muyeso de ions mkati de yankho. Muyenera kutero kuwerengera pH potengera kukhazikika. Werengani the pH Kugwiritsa ntchito equation ya pH: pH = -log[H3O+].

Kodi njira yowerengera pOH ndi yotani?

Ndiponso, a pOH (kapena OH kuthekera) ndi muyeso wa zoyambira kapena zamchere za yankho. Komanso se amagwiritsa pH = - chipika [H₃O⁺] kuyeza kuchuluka kwa ayoni a hydronium [H₃O⁺].

Momwe pH kapena pOH mtengo imawerengedwera

Ma equations ofunika kuti muwerenge pH kapena pOH mtengo

pH=−log[H3O+]
pOH=−log[OH-]
[H₃O⁺] = 10, XNUMX^-^pH
[OU^-] = 10, XNUMX^-^pOH
pH + pOH =pK_w = 14.00 pa 25 °C.

Kodi pali kusiyana kotani pakati pa kukula kwa pH ndi pOH?
