pH thiab pOH txhais tau tias tsis zoo ntawm cov ntsiab lus ntawm hydrogen lossis hydroxide ions hydroxide ions Hydrooxide 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. https://en.wikipedia.org › wiki › Hydroxide
Hydroxide - Wikipedia
. High pH txhais tau hais tias cov tshuaj yog qhov yooj yim thaum pOH siab txhais tau hais tias cov tshuaj yog acidic. … Yog li ntawm no cov ntsiab lus tseem ceeb ntawm pH yog tias nws sib npaug rau qhov tsis zoo log puag 10 ntawm qhov concentration ntawm protons hauv koj cov tshuaj.
Kev sib raug zoo ntawm pH thiab pOH yog dab tsi?
pH yog qhov ntsuas ntawm acidity ntawm cov kua thaum ntawm qhov tod tes pOH yog qhov ntsuas ntawm qhov tseem ceeb ntawm cov tshuaj, thiab thaum ob leeg muaj nqi sib npaug, ces cov tshuaj yuav nruab nrab. Cov pH ntawm txhua qhov kev daws tuaj yeem cuam tshuam nrog pOH.
pH thiab pH txawv li cas?
pH yog qhov ntsuas ntawm acidic / cov dej hauv paus. Qhov ntau yog los ntawm 0 txog 14, nrog rau 7 yog nruab nrab. pH tsawg dua 7 qhia tias acidity, whereas a pH ntau dua 7 qhia tias lub hauv paus. pH yog qhov ntsuas ntawm qhov txheeb ze ntawm cov hydrogen dawb thiab hydroxyl ions hauv dej.
pOH txhais li cas?
pOH yog ntsuas ntawm hydroxide ion (OH-)concentration of a solution. Xws li, nws tuaj yeem siv los ua qhov taw qhia ntawm cov khoom alkalinity lossis txawm tias nws cov hluav taws xob conductivity hauv qee kis. Tshwj xeeb tshaj yog, pOH yog qhov tsis zoo logarithm ntawm hydroxide ion cov ntsiab lus muab los ntawm kev qhia: pOH=14 - pH.
pOH piv txwv yog dab tsi?
POH ntawm kev daws yog qhov negative logarithm ntawm hydroxide-ion concentration . by this yields a [OH −] of 1.0 × 10 -10 M. Thaum kawg pOH ntawm cov tshuaj sib npaug -log(1.0 × 10 - 10)=10. Qhov piv txwv no qhia txog kev sib raug zoo hauv qab no.

Qhov txawv ntawm qhov taw qhia thiab qhov taw qhia yog dab tsi?
Raws li nouns qhov txawv ntawm qhov taw qhia thiab qhov taw qhia yog tias indicative yog (cov qauv sau ntawv) qhov taw qhia qhov taw qhia thaum qhov taw qhia yog tus taw tes lossis qhov ntsuas uas qhia qee yam. Puas qhia thiab qhia tib yam?
Puas yog txawv txawv thiab txawv txawv lossis cov lus sib txawv?
Cov lus txawv txawv thiab txawv txawv yog synonyms, tab sis txawv ntawm nuance. Tshwj xeeb, alienate tej zaum yuav los yog tsis qhia kev sib cais tab sis ib txwm hais txog kev poob kev hlub lossis kev txaus siab. Dab tsi yog lub ntsiab lus ntawm alienate?
