Hauv khov kho theem, txawm li cas los xij, tsis muaj qhov zoo li kev daws teeb meem. Los ntawm txhais, lub pH muaj feem xyuam rau cov concentration ntawm hydrogen ion solvated nyob rau hauv kev daws. Qhov ntawd ua tau ua ib tug aqueous tov, nyob rau hauv lub pH tau Feem ntau ntawm -2 txog 16.
Yog li ntawd, cov khoom puas tuaj yeem yog acidic?
Feem ntau carboxylic kua qaub yog cov khoom khib nyiab Nyob rau hauv chav tsev kub tab sis formic, acetic, propanoic, thiab butanoic kua qaub yog kua. Los ntawm txoj kev, ib txhia kua qaub yog gases hauv lawv daim ntawv ntshiab (xws li hydrochloric kua qaub los yog hydrofluoric kua qaub ). Sulphamic kua qaub yog a khov kho inorganic kua qaub.
Tsis tas li ntawd, pH tsuas yog rau cov kua dej xwb? Tsis yog Txhua Cov kua dej Muaj ib pH Tus nqi pH nkaus xwb muaj lub ntsiab lus hauv cov kua dej (hauv dej). Ntau yam tshuaj, suav nrog kua , tsis muaj pH tus nqi. Yog tsis muaj dej, tsis muaj pH . Piv txwv li, tsis muaj pH tus nqi rau cov roj zaub, roj av, lossis cawv ntshiab.
Kuj nug, puas yog txhua yam muaj pH sib npaug?
Cov pH ntsuas feem ntau hais tias muaj li ntawm 0 txog 14, thiab feem ntau cov kev daws teeb meem ua poob rau hauv qhov ntau, txawm tias nws ua tau qib pH qis dua 0 lossis siab dua 14. Txhua yam hauv qab 7.0 yog acidic, thiab txhua yam saum 7.0 yog alkaline , los yog yooj yim.
Dab tsi yog pH sawv rau hauv pH nplai?
muaj peev xwm hydrogen

Cov niam txiv muaj ntshav hom A thiab B puas tuaj yeem muaj menyuam nrog O?
Yog lawm, vim txhua tus neeg muaj ob 'genes' rau hom ntshav. Yog li ntawd, ob tug niam txiv uas muaj hom ntshav A lossis B, yog li ntawd, tuaj yeem tsim tau tus menyuam muaj ntshav hom O. Yog tias lawv ob leeg muaj AO lossis BO noob, txhua tus niam txiv tuaj yeem pub cov noob O rau cov xeeb ntxwv. Tom qab ntawd cov xeeb ntxwv yuav muaj OO noob, ua rau lawv cov ntshav hom O
Cov khoom puas tuaj yeem muab cais ua cov khoom yooj yim?
Cov ntsiab lus tsis tuaj yeem tawg mus rau hauv cov khoom yooj yim. Ib yam li ntawd, ib lub ntsiab lus tsis tuaj yeem hloov pauv mus rau hauv ib lub caij sib txawv. Cov khoom siv tshuaj yog qhov yooj yim ntawm cov khoom
Puas muaj qhov chaw nruab nrab ntawm cov khoom hauv cov khoom?
Feem ntau, cov khib nyiab yog denser dua cov kua, uas yog denser dua gases. Cov khoom hauv cov kua feem ntau tseem kov tab sis muaj qee qhov chaw nruab nrab ntawm lawv. Cov pa roj muaj qhov sib txawv loj ntawm lawv
Txoj cai thermodynamic twg hais tias koj Tsis tuaj yeem hloov 100 feem pua ntawm cov cua sov rau hauv cov khoom siv hluav taws xob ntawm cov lus teb xaiv?

Cov khoom puas tuaj yeem muaj nyob hauv lub dav hlau?
Nyob rau hauv geometry tej zaum yuav muaj nyob rau hauv ib lub dav hlau. Lub dav hlau txhais tau tias yog lub tiaj tus thiab ob sab saum npoo uas txuas mus txog qhov kawg. Cov lus tseeb yog - Hauv geometry, cov khoom yuav muaj nyob hauv qhov chaw peb sab. Hauv geometry, 3d duab muaj qhov tob, dav thiab qhov siab
