En Ok pool Reform Sifuna ukwabelana nawe ngeposi elandelayo, ejongene nayo Yintoni inqanaba le-pH ye-pool kunye nendlela yokulawula ngayo
Yintoni i-pH, ixabiso, ukubaluleka kunye nendlela yokuyilinganisa
Yintoni i-pH
I-pH ngumlinganiselo we-asidi okanye i-alkalinity yesisombululo esinamanzi.
Ke, njengoko sele sitshilo, I-PH ngumlinganiselo we-acidity okanye i-alkalinity ye-sutantica ebonisa ukuxinwa kwee-ion ze-hydrogen ezikhoyo kwizisombululo ezithile.
Imele ntoni i-akhronim pH?
- Kwelinye icala, yikhankanye loo nto I-akhronimi i-pH imele amandla e-hydrogen okanye amandla e-ion hydrogen.

I-pH ye-pool leyo
Yintoni i-pH ye-pool: I-pH yinto enokubakho ye-hydrogen, ixabiso elihambelana nokuxinana kwee-ion ze-hydrogen emanzini edama lakho kwaye ngenxa yoko ngumlinganiso obonisa iqondo le-asidi okanye isiseko samanzi. Ngoko ke, i-pH ijongene nokubonisa ukuxinwa kwe-H + ion emanzini, ukugqiba i-acidic okanye uphawu olusisiseko.
Amaxabiso e-pH echibini afanelekileyo
Isikali se-pH sisuka kwi-1 ukuya kwi-14, kunye ne-pH 7 isisombululo esingathathi hlangothi.
I-pH lixabiso elibonakaliswa ngesikali se-logarithmic phakathi kwamaxabiso 0 kunye ne-14.
Ngoko ke, ukwenzela ukulinganisa i-asidi yolwelo, kwaye kwimeko yethu yamanzi echibi, iikhemikhali kwaye ngoku siya kusebenzisa. isikali se-pH esibandakanya amaxabiso ukusuka ku-0 ukuya kwi-14.
pool efanelekileyo pH
I-pH yephuli: yenye yezona parameters ezibalulekileyo kugcino lwamachibi.
Ixabiso elifanelekileyo lepH yamanzi echibini: phakathi kwe-7.2 kunye ne-7.6 uluhlu olufanelekileyo lwe-pH engathathi hlangothi.
Lo nto, Ukuba ne-pH kolu luhlu akulunganga kuphela ukuba namanzi kwiimeko ezifanelekileyos okoko i-pH ephantsi okanye ephezulu yehlisa kakhulu isiphumo sokubulala iintsholongwane, kodwa kunjalo ilungele ulusu kunye namehlo abahlambi.

ph amachibi anetyuwa
- Ngokwenene, i ichibi elinetyuwa ph iza kufana namachibi aphathwa ngeklorin ukususela ekugcinweni kwe echibini Ukusebenzisa ityuwa kufuna ukubekwa kweliso rhoqo pH zamanzi.
- Ngoko ke, i-pH yamachibi etyuwa kufuneka ibe nayo pH ibekwe phakathi kwe-7 kunye ne-7,6, inqanaba elifanelekileyo liphakathi kwe-7,2 kunye ne-7,4.

Ngawaphi amaxabiso e-pH
Isikali se-pH sisuka kwi-1 ukuya kwi-14, kunye ne-pH 7 isisombululo esingathathi hlangothi.
Ngoko ke, kuvela ukuba i-pH lixabiso elibonakaliswa nge-logarithmic scale phakathi kwamaxabiso 0 (i-acidic kakhulu) kunye ne-14 (i-alkaline kakhulu); Phakathi sifumana ixabiso le-7 elifakwe kwikhathalogu njengengathathi hlangothi.
Isikali se-pH isalathisi jikelele se-pH
Kuthetha ukuthini ukuba into ene-acidic okanye i-alkaline pH level?
Yintoni iiasidi kunye neziseko?
I-Acids kunye neziseko zizinto ezikhoyo kwindalo kwaye zahlulwa ngokwenqanaba le-pH, oko kukuthi, ngeqondo le-asidi okanye i-alkalinity. Ukumiselwa kokuba izinto zineasidi okanye ialkaline kulawulwa yinqanaba leasidi okanye ialkalinity elinganiswe kwisikali se-pH kunye noluhlu ukusuka ku-0 (oluneasidi kakhulu ukuya kwi-14 (i-alkaline egqithisileyo). nangona kunjalo zinemisebenzi emininzi yemizi-mveliso neyabantu.
Ziziphi izinto ezineasidi?
- Inqanaba le-asidi ye-pH: pH ngaphantsi kwe-7
Kuthetha ukuthini ukuba ixabiso le-pH li-acidic?
- Ukuba into eneasidi ithetha ukuba ityebile kuH+ (i-hydrogen ions): pH ngaphezulu kwe-7
- Ngoko ke, Iiasidi zizinto ezinepH engaphantsi kwe-7. (i-pH yamanzi elingana ne-7, ithathwa njengengathathi hlangothi), i-chemistry yayo idla ngokuqulatha izixa ezikhulu ze-hydrogen ion xa ukongeza amanzi. Zidla ngokusabela nezinye izinto ngokuphulukana neeprotons (H+).
Ziziphi izinto ezingathathi hlangothi?
- Ixabiso le-pH eliphakathi: i-pH ilingana ne-7-
Kuthetha ukuthini ukuba ixabiso le-pH lingathathi hlangothi?
- I-pH ngumlinganiselo wokuba amanzi aneasidi/ayisiseko kangakanani na.
- Uluhlu luvela kwi-0 ukuya kwi-14, kunye ne-7 engathathi hlangothi.
Ziziphi izinto zealkaline?
- Izinto ezinesiseko okanye i-alkaline pH: i-pH enkulu kune-7.
Kuthetha ukuthini xa ixabiso le-pH liyi-alkaline?
- Ukuba into ethile inealkaline ithetha ukuba ihlwempuzekile kwi-H+ (okanye zizityebi kwiziseko ze-OH-, eyenza ukuba iH+).
- Kuyo yonke le nto, Iziseko, kwelinye icala, zizinto ezinepH enkulu kuno-7., ezithi kwizisombululo ezimanzi zihlala zibonelela ngeeion zehydroxyl (OH-) esiphakathini. Zidla ngokuba zii-oxidants ezinamandla, oko kukuthi, zisabela ngeeprotons ezivela kwindawo engqongileyo.
Umahluko phakathi kwe-pH kunye nexabiso le-pOH
Umahluko phakathi kwexabiso le-pH kunye ne-pOH
Lithini ixabiso le-pH eliqhelekileyo?
- Ngandlela ithile, i-pH ngumlinganiselo lowo isetyenziselwa ukuseka inqanaba le-asidi okanye i-alkalinity yesisombululo. I "p" imele "ithuba", yiyo loo nto i-pH ibizwa ngokuba: amandla e-hydrogen.
Yintoni ixabiso le-pOH?
- Kwelakho icala. I-pOH ngumlinganiselo wokuxinana kwee-ion ze-hydroxyl kwisisombululo. Ichazwa njengesiseko se-10 ye-logarithm engathandekiyo yoxinaniso lwe-ion ye-hydroxyl kwaye, ngokungafaniyo ne-pH, isetyenziselwa ukulinganisa inqanaba le-alkalinity yesisombululo.

Indlela yokubala i-pH
Isikali se-pH sibalwa ngokusebenzisa i-logarithm ethabathayo.
Ixabiso le-pH lilogarithmic
pH yiyo ilogarithm yoxinaniso lwe-H ions+, ngophawu olutshintshileyo: Ngokufanayo, i-pOH ichazwa njenge ilogarithm yoxinaniso lweeOH ions-, kunye nophawu olutshintshileyo: Ubudlelwane obulandelayo bunokusekwa phakathi kwe pH kunye ne-POH. Ukuqala kwinkcazo yemveliso ye-ionic yamanzi (Kw):
I-Logarithmic pH Formula
- I-Log pH Ifomula: Bala i-pH usebenzisa i-pH equation: pH = -log[H3O+].
Kuthetha ukuthini ukuba ixabiso le-pH lilogarithmic
Inyaniso yokuba i-pH yi-logarithmic ithetha ukuba phakathi kweyunithi nganye yesikali kukho umlinganiselo we-10 umahluko,
- Ngoko ke, oku kuthetha ukuba i-pH 5 i-acidic ephindwe ka-10 kune-pH 6, kwaye i-pH 4 iphindwe kayi-100 kune-pH 6.
Indlela yokubala i-pH nge-logarithms?
umlinganiselo we I-pH ibalwa ngokusebenzisa i ilogarithm embi. A ilogarithm u-negative ubonisa ngokulula ukuba inani kufuneka lahlulwe kangaphi. Inxaki ye pH inokubhalwa ngolu hlobo lulandelayo: pH = -log[H3O+]. Ngamanye amaxesha i-equation ibhalwa ngolu hlobo: pH = -log[H+].
Isizathu sokuphuhliswa kwesikali sexabiso le-pH: Isikali se-pH saphuhliswa, kuthatyathwa amanzi njengomgangatho.
- Yinyaniso yovavanyo ukuba kuphela i-moles enye kwi-1 ye-moles yamanzi i-ionize ibe yi-H + kunye ne-OH enye.
- Lo ngumlinganiselo ofanayo negram enye yeeyoni zehydrogen kwiilitha ezingama-10.000.000 zamanzi.
- Ngoko ke, ilitha yamanzi iqulethe i-1/10.000.000 (okanye) i-1/107 yegram ye-H +. Kusetyenziso lwemihla ngemihla, ngumfanekiso 'wePotency' kuphela osetyenzisiweyo, kunye nesimboli ye-pH ebekwe phambi kwawo.

Iziphumo eziphezulu ze-pH pool: Kwenzeka ntoni ukuba i-pH ye-pool iphezulu
- Okokuqala, iziphumo eziphezulu ze-pH pool zenza kube nzima ukuba amanzi ajikeleze ngokufanelekileyo kwaye amaxesha amaninzi, yingxaki evela ekusebenziseni ezinye iintlobo zeefilitha okanye izifudumezi zamanzi.
- Iimpawu emzimbeni wethu zilusu olomileyo kwaye lucaphukile.
- Ngokufanayo, amanzi anamafu atshintsha i-pH ye-pool, ngamanye amaxesha ngokusebenzisa isixa esinganelanga seklorini okanye imveliso yokusetyenziswa kwemihla ngemihla ukubulala iintsholongwane emanzini.
- Ngokungathi oko kwakunganelanga, i-pH ephezulu iya kukhuthaza ukubunjwa kweediphozithi zekalika echibini eliya kugqiba ngamanzi acwebileyo. Ezi iidiphozithi zekalika ziya kufakwa kwimibhobho kunye nolunye ufakelo, oluchaphazela uzinzo kunye nokusebenza ngokufanelekileyo. Baya kuphinda banamathele kwiindonga kunye nemigangatho, ukuguqula ukubonakala kunye nokucoceka kwedama.
Ngezantsi, ukuba inomdla kuwe, sikubonelela ngekhonkco kwi iphepha apho sihlalutya zonke iziphumo ze-pH ephezulu kumachibi okubhukuda kunye nezizathu zabo ezinokwenzeka.
