Piv txwv li, ib qho piv txwv ntawm cov dej deionized raug huab cua tuaj yeem nqus sai sai C02 thiab tsim carbonic acid (H2CO3) uas tuaj yeem hloov pauv pH ntawm cov dej nruab nrab ntawm 7.0 kom poob li. qis 5.6. Nco ntsoov tias pH nplai yog logarithmic thiab qhov no sawv cev rau kev hloov pauv loj heev hauv chemistry!
Puas deionized dej puas cuam tshuam pH?
pH electrodes yuav tsis muab pH qhov tseeb hauv cov dej distilled lossis deionized vim cov dej distilled thiab deionized tsis muaj ions txaus rau cov electrode ua haujlwm zoo. Cov ntawv nyeem yuav ntws thiab tsis muaj qab hau.
PH hloov pauv yog tias koj ntxiv dej?
Ntxiv dej rau cov kua qaub lossis cov hauv paus yuav hloov nws cov pH Dej feem ntau yog dej molecules yog li ntxiv dej rau hauv cov kua qaub los yog hauv paus txo cov concentration ntawm ions hauv cov tshuaj. Thaum cov kua qaub diluted nrog dej, qhov concentration ntawm H +ions txo qis thiab pH ntawm cov tshuaj nce mus rau 7.
YPuas yog deionised dej pH nruab nrab?
Deionized water pH is 7 (neutral). Niaj hnub no RO tshuab tau dav siv los sib npaug dej acidity thiab kom txo qis cov zaub mov concentration. Koj tseem tuaj yeem distil dej - uas yog txoj kev siv dej brewing. Cov dej distilled kuj yuav muab cov dej nruab nrab rau koj.
Puas yog dej deionized ntau acidic?
Hauv kev xav, qhov tsis muaj ions txhais tau hais tias cov dej deionized yuav tsum muaj pH ntawm 7. Txawm li cas los xij, thaum dej deionized los rau hauv kev sib cuag nrog atmospheric carbon dioxide, nws nqus cov pa ua carbonic acid, uas tuaj yeem txo cov dej pH kom tsawg li 5.5.
