umehluko phakathi kwe-ph ne-poh

Inkomba yokuqukethwe kwekhasi

En Ok Pool Reform, kulesi sigaba ngaphakathi kwe Izinga le-pH lamachibi okubhukuda sizophatha i umehluko phakathi kwe-ph ne-poh kumanani wamanzi wechibi.

Iyini i-pH echibini futhi amazinga ayo kufanele abe kanjani?

Liyini izinga le-pH lechibi nokuthi ungayilawula kanjani

Kuleli khasi ungafunda ngezinga le-pH yephuli: liyini izinga le-pH elifanelekile lechibi, amanani alo angenzeka, izindlela zokulilinganisa, ukulilungisa nokulilawula. Iyini i-pH: I-Coefficient ekhombisa izinga le-acidity noma isisekelo samanzi. Ngakho-ke, i-pH inesibopho sokukhombisa ukugcwala kwama-ion e-H+ emanzini, inquma i-acidic noma uhlamvu oluyisisekelo.

Isho ukuthini i-pH ekahle kumachibi okubhukuda (7,2-7,4)

I-acronym pH imele i-hydrogen engaba khona futhi iyisilinganiso esibonisa ubumuncu noma ubuqiniso bamanzi.

Ngakho, I-pH isho amandla e-hydrogen, inani elihambisana nokuhlangana kwama-ion e-hydrogen emanzini echibini lakho futhi ngakho-ke iyi-coefficient ebonisa izinga le-asidi noma isisekelo samanzi. Ngakho-ke, i-pH iphethe ukukhombisa ukugcwala kwama-ion e-H+ emanzini, ukucacisa i-acidic yawo noma uhlamvu oluyisisekelo.

Isikali samanani e-pH amanzi echibi lokubhukuda

Imaphi amanani afakwa isikali sokulinganisa i-pH yamanzi echibini?

Isikali sokulinganisa i-pH sihlanganisa amanani asuka ku-0 kuye ku-14.
Ikakhulukazi u-0 one-acidic kakhulu, u-14 uyisisekelo kakhulu futhi obeka i-pH emaphakathi ku-7.
Lesi silinganiso sinqunywa inani lama-ion e-hydrogen amahhala (H+) entweni.

Kungani sidinga i-pH?

I-pH isilinganiso esisetshenziselwa ukucacisa ubumuncu noma ubuqiniso besisombululo esinamanzi. Ukuthi isixazululo esinamanzi siphendula njenge-asidi noma isisekelo kuncike ekuqukethe ama-ion e-hydrogen (H+).

Kodwa-ke, ngisho namanzi ahlanzekile ngamakhemikhali futhi angathathi hlangothi aqukethe ama-ion e-hydrogen ngenxa yokuzihlukanisa kwamanzi.

$H_2O \umcibisholo omudekwesokunxelekwesokudla H^+ + OH^-$

Kuyaziwa ukuthi ekulinganisweni ngaphansi kwezimo ezijwayelekile (750 mmHg kanye no-25°C), i-1 L yamanzi ahlanzekile iqukethe. $10^{-7}$ imvukuzane $H^+$ y $10^{-7}$ imvukuzane $OH^-$ ama-ion, ngakho-ke, amanzi asezingeni lokushisa elijwayelekile nokucindezela (STP) ane-pH engu-7.

Okufanele ukwenze lapho i-pH yechibi lethu AYIlawulwa

Yazi imiphumela yechibi eliphezulu le-pH kanye nezimbangela ze-pH ephezulu echibini lakho

Kule bhulogi sikhuluma nge-pH ye-pool ephezulu, imiphumela kanye nezimbangela zokungalingani. Ithini i-pH yamachibi ayisisekelo noma ichibi le-alkaline i-pH: Uma inani lama-ion we-Hydroxide likhulu kunele-Hydrogen ion, i-pH ibizwa nge-Basic OH- > H+. Ngakho-ke, uma i-pH ingaphezu kuka-7,4, amanzi kuthiwa ayisisekelo futhi i-pH yamanzi echibi ibizwa ngokuthi i-alkaline. Futhi funda indlela yokwehlisa i-pH ye-alkaline echibini nokuthi kwenzekani uma ngine-pH ephezulu echibini.

Indlela yokukhulisa i-pH yechibi nokuthi kwenzekani uma iphansi

Indlela yokukhulisa i-PH yechibi: Ukugcina ikhwalithi yamanzi kanye namazinga e-pH alungile, lezi kufanele zibe phakathi kuka-7,2 no-7,6. Funda indlela yokukhulisa i-pH yechibi futhi wazi imiphumela yalokho okwenzekayo uma i-pH yechibi iphansi.

Indlela Yehlisa Ichibi Eliphezulu noma Eline-alkaline pH

Indlela yokwehlisa i-PH yechibi: Ukugcina ikhwalithi yamanzi kanye namazinga e-pH alungile, lezi kufanele zibe phakathi kuka-7,2 no-7,6. Funda indlela yokwehlisa i-pH yechibi futhi wazi imiphumela yalokho okwenzekayo uma i-pH yokubhukuda iphezulu.

Imihlahlandlela yokuthi kwenziwa kanjani ukunakekelwa kwechibi ngaphezu kwe-pH: ukuhlanza amanzi kanye nokubulala amagciwane

Umhlahlandlela owusizo ukwazi ukuhlanza ichibi

Ichibi elihlanzekile: zonke izinhlobo zezeluleko nezexwayiso kanye nomhlahlandlela wakho kokubili ukusetha nokulungisa okujwayelekile.

Umhlahlandlela wokunakekela ichibi elinamanzi asesimweni esihle

Kuleli khasi sihlanganisa yonke into ehlobene nokugcinwa kwe-pool okujwayelekile: ukukhishwa kwamanzi, ukuhlungwa kwamanzi, ukuhlanzwa kwamachibi kanye nokugcinwa kwe-pool liner

Amanani e-pH ane-Acidic, neutral kanye ne-alkaline

Isho ukuthini i-acidic nesisekelo se-pH?

I-Acid ne-pH eyisisekelo: Yazi amanani nokuthi kusho ukuthini ukuthola inani elilodwa noma elinye kuye ngokuthi yisiphi isisombululo (ikakhulukazi esigxile kumachibi okubhukuda).

Ukuhlukaniswa Kwesikali Samanani we-pH

Ayini amanani we-pH

yini i-ph pisci6

Isikali se-pH sisuka ku-1 siye ku-14, kanti i-pH 7 iyisixazululo esingathathi hlangothi.

Ngakho-ke, kuvela ukuthi i-pH iyinani elivezwa esikalini se-logarithmic phakathi kwamanani 0 (okune-asidi ngokwedlulele) kanye no-14 (okune-alkaline ngokwedlulele); Phakathi sithola inani elingu-7 libhalwe njengeliphakathi nendawo.

Inkomba ye-pH yendawo yonke yesikali se-pH

Kusho ukuthini ukuthi into ine-pH ene-asidi noma ene-alkali?

Ayini ama-asidi nezisekelo?

Ama-Acid nezisekelo yizinto ezikhona emvelweni futhi zihlukaniswa ngeleveli yazo ye-pH, okungukuthi, ngezinga le-acidity noma i-alkalinity. Ukunqunywa kokuthi izinto zine-acidic noma i-alkaline kulawulwa yizinga le-asidi noma i-alkalinity elinganiswa ngesikali se-pH futhi isukela ku-0 (ine-acidi ngokwedlulele iye ku-14 (i-alkaline ngokwedlulele). Kokubili, nokho, ngokuvamile kuyizinto ezonakalisayo, ezivamise ukuba nobuthi, obuthi nokho banezicelo eziningi zezimboni nezabantu.

Yiziphi izinto ezine-acidic?

Izinga le-Acid pH: pH ngaphansi kuka-7

Kusho ukuthini ukuthi inani le-pH line-acidic?

Ukuthi into ethile ine-acidic kusho ukuthi inothile nge-H⁺ (ama-hydrogen ions): i-pH enkulu kuno-7
Ngakho, Ama-Acids yizinto ezine-pH engaphansi kuka-7. (i-pH yamanzi ilingana no-7, ibhekwa njengengathathi hlangothi), ikhemikhali yayo ngokuvamile iqukethe amanani amakhulu e-hydrogen ion lapho wengeza amanzi. Ngokuvamile zisabela nezinye izinto ngokulahlekelwa ama-proton (H⁺).

Yiziphi izinto ezingathathi hlangothi?

Inani le-pH emaphakathi: i-pH ilingana no-7-

Kusho ukuthini ukuthi inani le-pH alithathi hlangothi?

I-pH iyisilinganiso sokuthi amanzi ane-acidic/ayisisekelo kangakanani.
Ububanzi busuka ku-0 kuye ku-14, kanti u-7 ungathathi hlangothi.

Yiziphi izinto ezine-alkaline?

Izinto ezine-pH yesisekelo noma ye-alkali: pH enkulu kuno-7.

Kusho ukuthini uma inani le-pH liyi-alkaline?

Ukuthi into ine-alkaline kusho ukuthi impofu ku-H⁺ (noma ucebile ngezisekelo ze-OH^-, okwenza i-H⁺).
Kukho konke lokhu, Izisekelo, ngakolunye uhlangothi, ziyizinto ezine-pH enkulu kuno-7., okuthi ezixazululweni ezinamanzi ngokuvamile anikeze ama-ion hydroxyl (OH^-) phakathi. Avame ukuba ama-oxidants anamandla, okungukuthi, asabela ngama-protons avela endaweni ezungezile.

Umehluko phakathi kwamanani we-pH ne-pOH

ph ifomula yesikali sesikali

Zihlobene kanjani futhi yimuphi umehluko phakathi kwezilinganiso ze-ph ne-poh?

umehluko phakathi kwezilinganiso ze-ph ne-poh

Yiqiniso, umsebenzi we-ion uncike ekugxilweni kwe-ion futhi lokhu kuchazwe ku-equation

Izibalo zomsebenzi we-pH/poH ion

$a_{H^+}=f \cdot [H^+]$
kuphi,
$H^+$ - Umsebenzi we-hydrogen ion
$f$ - umsebenzi we-coefficient ye-hydrogen ion
$[H^+]$ - Ukuhlushwa kwe-hydrogen ion

I-coefficient yomsebenzi iwumsebenzi wokugxilisa i-ion futhi isondela ku-1 njengoba isisombululo siya ngokuya sincipha.

Ukuze uthole izixazululo ze-dilute (ezikahle), isimo esijwayelekile se-solute ngu-1,00 M, ngakho-ke i-molarity yayo ilingana nomsebenzi wayo.

Ngakho-ke, ezinkingeni eziningi ezithatha izixazululo ezifanele singasebenzisa i-logarithm kusisekelo esingu-10 sokugxila kwe-molar, hhayi umsebenzi.

Umehluko phakathi kwenani le-pH ne-pOH

ph kanye nesikali senani le-poh

Liyini inani le-pH elivamile?

Ngandlela thile, i-pH iyisilinganiso sokuthi esetshenziselwa ukusungula izinga le-acidity noma i-alkalinity yesisombululo. Igama elithi “p” limele “okungenzeka”, yingakho i-pH ibizwa ngokuthi: amandla e-hydrogen.

Liyini inani le-pOH?

Ngokwengxenye yakho. I-pOH isilinganiso sokuhlangana kwama-ion e-hydroxyl esixazululweni. Ivezwa njengesisekelo se-logarithm engu-10 ye-negative logarithm ye-hydroxyl ion concentration futhi, ngokungafani ne-pH, isetshenziselwa ukukala izinga le-alkalinity lesisombululo.

bala inani le-ph

Ibalwa kanjani i-pH noma inani le-pOH?

Ithini ifomula yamanani esikali se-ph?

Njengoba sekwaziwa kakade, emkhakheni wesayensi, i pH yisilinganiso de ama-ion ngaphakathi de isixazululo. Kungase kudingeke wenze kanjalo bala pH ngokusekelwe ekugxiliseni ingqondo. Bala i- pH Ukusebenzisa i-equation ye pH: pH = -log[H3O+].

Ithini ifomula yokubala i-pOH?

Futhi, i pOH (noma amandla we-OH) isilinganiso sesisekelo noma i-alkalinity yesixazululo. Futhi se isebenzisa i-pH = – log [H₃O⁺] ukukala ukugcwala kwama-ion e-hydronium [H₃O⁺].

Ibalwa kanjani i-pH noma inani le-pOH

Izibalo Ezibalulekile zokubala inani le-pH noma le-pOH

pH=−log[H3O+]
pOH=−log[OH−]
[H₃O⁺= 10^-^pH
[oh^-= 10^-^pOH
pH + pOH =pK_w = 14.00 ku-25 °C.

Uyini umehluko phakathi kwesilinganiso samanani we-pH kanye nese-pOH?
