Yenzelwe ntoni ipH yedama?
Ukuzimisela kwe-pH yenye yezona nkqubo zibaluleke kakhulu kwaye zisetyenziswa ngokubanzi kwi-chemistry kunye ne-biochemistry. I-pH imisela iimpawu ezininzi eziphawulekayo zesakhiwo kunye nomsebenzi weemolekyuli, ngoko ukuziphatha kweeseli kunye nezinto eziphilayo.
Umgangatho wamanzi echibini uxhomekeke ngokuthe ngqo kwi-pH, ukuba ayigcinwanga ingabangela izifo.
I-pH inxulumene ngokusondeleyo nomgangatho wamanzi kumadama okuqubha. Oku kunjalo ngenxa yokuba iklorini inesiphumo kuphela ukuba i-pH yamanzi echibini iphakathi kwe-6.5 kunye ne-8. Ukuba i-pH yamanzi inkulu kuno-8 okanye ngaphantsi kwe-6.5, kungakhathaliseki ukuba i-chlorine ifakwe kangakanani, ayiyi kusebenza. Ngenxa yesi sizathu, kubalulekile ukuqinisekisa ukuba i-pH ihlala iphakathi kwe-6.5 kunye ne-8. Eli lungiselelo lingundoqo ekuqinisekiseni ukuba idama lihlala likwimeko efanelekileyo. I-pH yamanzi ephezulu kakhulu (ngaphezulu kwe-8) ibangela amanzi amnyama, ukuhluma kunye nokucaphuka kwamehlo, iindlebe, impumlo kunye nomqala.
Kutheni kubalulekile ukulawula ipH yamadama okuqubha?
Ukucoceka kwamachibi okubhukuda yinto ebaluleke kakhulu, kunye nokugcina i-pH rhoqo ekhusela ukubonakala kwe-microorganisms kwaye iqinisekisa impilo yabahlambi.s.
Ukusebenzisa izinto zeekhemikhali kwiindawo zokubhukuda kubalulekile ngenxa yezizathu ezininzi, phakathi kwazo, impilo ephilileyo yamanzi kunye nokuphepha ukubonakala kweebhaktheriya kunye ne-microorganisms. Nangona kunjalo, ezi zongezo zinokungalinganisi i-pH yamanzi, zidale imingcipheko kwimpilo yabantu. Ngenxa yesi sizathu, ukubaluleka kokulawula esi salathisi kufuneka kuqondwe, yintoni indima edlalwa ezinye izinto, ezifana i-caustic soda kumachibi okuqubha kunye nokuba zeziphi izicwangciso-qhinga zokuphumeza ukuthobela amanyathelo okhuseleko ekusebenzeni kwezi zithuba.
I-pH yisalathiso se-alkalinity (acidity) samanzi, ngokuqhelekileyo, kufuneka sibe phakathi kwe-7,2 kunye ne-7,6. Esi sibonakaliso kufuneka silinganiswe kunye nesalathisi se-chlorine, ekubeni ukufaneleka kwamanzi okuhlamba kuxhomekeke kwezi zinto zimbini. Kwiingcali ezininzi, ixabiso elifanelekileyo leklorini emanzini yi-1 ppm (iinxalenye ngesigidi) kunye ne-alkalinity 125 okanye i-150 ppm.
I-pH yendawo yokuqubha ithathwa njenge-acidic xa ingaphantsi kwe-7,2 kunye ne-alkaline xa ingaphezulu kwe-7,6. Iziphumo kwimpilo yomntu oqubhayo echibini eline-acidic pH kukurhawuzelela nokutshisa emehlweni, impumlo nolusu, ukucaphuka komqala, ukubonakala kwe-eczema, ukoma, ukurhawuzelela, ukucaphuka, phakathi kwabanye.
Ukongezelela, i-acidity yamanzi inokuba nefuthe elithe ngqo ekugugile kunye nokukrazula kwezixhobo zamachibi, ngakumbi kwezo zintsimbi okanye iinxalenye zesamente ezinokutshatyalaliswa ngumgangatho ophezulu we-asidi.
Imiphumo yokuba ne-pH ephezulu kune-7,6 iya kubonakala ngakumbi emanzini kunempilo yabahlambi. Nangona abantu abahlamba echibini le-alkaline baya kuba neempawu ezifana nesikhumba esomileyo nesicatshungulwayo, ingxaki enkulu iya kuba yimeko embi yamanzi, eya kuba ngamafu, ibe luhlaza, ibe nephunga elibi kwaye iququzelele ukubonakala kwe-microbes, ibhaktheriya kwaye ubulembu . Ngale ndlela, nangona inqanaba leklorini linyuswa ukuze libulale iintsholongwane, akukho nto iya kufezekiswa ukuba i-pH ayilawulwa.

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.
