Ntawm pH nplai, pH qhov tseem ceeb hauv qab 7 sawv cev rau cov kua qaub (hydrogen ion kev ua ntau dua hydroxide ion hydroxide ion Hydroxide yog diatomic anion nrog tshuaj formula OH - Nws muaj cov pa oxygen thiab hydrogen atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa cov hluav taws xob tsis zoo. Nws yog ib qho tseem ceeb tab sis feem ntau me me ntawm cov dej. ib nucleophile, thiab catalyst. https://en.wikipedia.org › wiki › Hydroxide
YHydroxide - Wikipedia
kev ua) thaum qhov tseem ceeb tshaj 7 sawv cev rau cov kev daws teeb meem. … Yuav kom tswj tau yooj yim thiab sawv cev rau ntau yam ntawm cov dej num ion, siv logarithmic pH nplai.
PH ntsuas qhov ntsuas logarithmic li cas?
pH yog qhov ntsuas logarithmic. Qhov no txhais tau tias rau txhua tus lej hloov pauv hauv pH, acidity (H+ concentration) hloov 10 zaug . Piv txwv li, cov tshuaj nrog pH ntawm 4 muaj 10 npaug ntau dua H+ dua li cov tshuaj nrog pH ntawm 5.
Vim li cas pH nplai tsis yog kab?
ntau cov kua qaub yog ib qho pH dua lwm tus? Lo lus nug no tsis yog yooj yim heev los teb, vim tias pH tsis nyob ntawm qhov ntsuas kab, zoo li tus kav. Hloov chaw, nws nyob ntawm qhov ntsuas tsis zoo Cov av uas siab dua hauv acidity yeej muaj pH me me, ua tsaug rau qhov ntsuas tsis zoo. Cov pH ntsuas ntawm 0 txog 14.
pH thiab log cuam tshuam li cas?
Lub ntsiab lus meej ntawm pH yog "qhov tsis zoo ntawm logarithm ntawm kev ua haujlwm ntawm hydrogen ion hauv kev daws". Rau lub hom phiaj siv tau, qhov kev ua si yog kwv yees li concentration hauv moles / L: pH=- log 10 ([H+]) ."- log 10 (X)".
Vim li cas pH siv hloov H+?
Qhov laj thawj tom ntej ntawm kev siv pH nplai hloov H+ thiab OH- ntau yog qhov hauv dilute cov kev daws teeb meem, qhov concentration ntawm H+ yog me me , ua rau qhov tsis yooj yim ntawm kev ntsuas nrog ntau qhov decimal, xws li 0.000001 M H +, los yog muaj peev xwm tsis meej pem cuam tshuam nrog kev tshawb fawb, xws li 1 × 10-6 M H …
