Raws li kev daws tau yooj yim dua (siab dua [OH-]), ua pH nce . Raws li cov pH ntawm ib qho kev daws txo qis los ntawm ib qho pH unit, ua concentration ntawm H+ nce los ntawm kaum lub sij hawm. Raws li cov pH ntawm ib qho kev daws teeb meem nce los ntawm ib pH unit, ua concentration ntawm OH- nce los ntawm kaum lub sij hawm.
Xav txog qhov no, puas pH hloov nrog concentration?
Yog, tus nqi ntawm cov khoom noj muaj feem xyuam rau nws pH . pH yog txhais raws li tus nqi tsis zoo ntawm lub cav ntawm concentration ntawm hydrogen los yog hydronium ions hauv kev daws. Thaum tus nqi ntawm cov khoom noj kev hloov , cov concentration hloov , thiab lwm yam ua pH.
H + concentration cuam tshuam li cas pH? Qhov siab dua H + concentration , qhov qis dua pH , thiab siab dua OH- concentration , qhov siab dua pH . Ntawm qhov nruab nrab pH ntawm 7 (dej ntshiab), lub concentration ntawm ob qho tib si H+ ions thiab OH- ions yog 10?7 M. Vim qhov kev cuam tshuam no, H+ thiab OH- muaj feem xyuam rau cov ntsiab lus ntawm cov kua qaub thiab cov hauv paus.
Hauv qhov no, vim li cas ntxiv ib lub hauv paus nce pH?
Ntxiv ib acid nce qhov concentration ntawm H3O+ ions hauv kev daws teeb meem. Ntxiv ib lub hauv paus txo qhov concentration ntawm H3O+ ions hauv kev daws teeb meem. Yog ib puag yog ntxiv rau cov kua qaub acidic, cov tshuaj ua acidic tsawg thiab txav mus rau nruab nrab ntawm cov pH nplai.
Tus nqi pH twg qhia tias muaj ntau dua ntawm OH?
Kev daws nrog ib siab Tus naj npawb ntawm hydrogen ions yog acidic thiab muaj tsawg tus nqi pH . Kev daws nrog ib siab tus lej ntawm hydroxide ions yog qhov yooj yim thiab muaj tus nqi pH siab . Cov pH ntsuas nyob ntawm 0 txog 14, nrog rau a pH ntawm 7 ua nruab nrab.

Lub siab puas nce nrog cheeb tsam?
Yog tias koj siv tib lub zog ntawm thaj tsam ntawm 1 sqaure meter, lub siab yog 10 N ib square meter. Yog li, rau tib lub zog, yog tias thaj chaw txo qis, lub siab nce
Cov cheeb tsam puas nce nrog Perimeter?
Cov lus teb luv luv: muab tib lub cheeb tsam, ib daim duab tsis tu ncua nrog ntau sab yuav npog ntau thaj chaw
Puas yog cov viscosities ntawm magmas nce nrog nce feem pua ntawm silica?
Lub viscosities ntawm magmas nce nrog nce feem pua ntawm silica. Kev tawg ntawm Hawaii volcanoes tej zaum yuav piav raws li tawg nyob rau hauv piv rau 1980 Mount St. Helens eruption. Basaltic lavas feem ntau yog kub dua thiab khov dua li andesite lavas
Puas yog lub zog kinetic nce nrog qhov siab?
Qhov siab dua ib yam khoom yog qhov ntau dua nws lub peev xwm gravitational. Raws li feem ntau ntawm GPE no tau hloov mus rau hauv lub zog kinetic, qhov siab dua ntawm cov khoom pib los ntawm qhov nrawm dua nws yuav poob thaum nws tsoo hauv av. Yog li kev hloov pauv ntawm lub zog gravitational nyob ntawm qhov siab ntawm qhov khoom txav mus los
Puas solubility nce nrog boiling point?
Qhov ntau dua lub solubility ntawm ib tug solute, qhov ntau dua lub boiling point. Yog hais tias peb muaj ob lub tebchaw sib piv, qhov ntau soluble compound yuav muaj ntau hais nyob rau hauv kev daws. Nws yuav muaj molarity ntau dua. Lub boiling point nce, thiab li no lub boiling point, yuav siab dua rau cov ntau soluble compound
