Dilute Solution ntawm Paub Molarity

Cov tshuab xam zauv siv tus qauv M1V1 = M2V2 qhov twg "1" sawv cev rau cov ntsiab lus tseem ceeb (piv txwv li kev daws teeb meem Molarity thiab ntim) thiab "2" sawv cev rau diluted tej yam kev mob (piv txwv li xav ntim thiab Molarity ).

Raws li, koj ua li cas xam cov concentration siv dilution factor?

Faib qhov ntim xav tau los ntawm dilution yam (400 ml / 8 = 50 ml) los txiav txim qhov ntim ntawm chav tsev. Cov dilution Tom qab ntawd ua raws li 50 ml tshuaj tua kab mob + 350 ml dej.

Tom qab, lo lus nug yog, dab tsi yog tus qauv rau kev suav dilution? Yuav ua kom tus nqi tas li ntawm a dilute kev daws teeb meem los ntawm kev daws teeb meem, koj tuaj yeem siv cov qauv : C1V1 = C2V2 qha: v1 = Qhov ntim ntawm cov khoom lag luam xav tau los ua cov tshuaj tshiab. C1 = Concentration of stock solution.

Raws li, koj ua li cas xam cov molarity ntawm cov tshuaj?

Yog xam molarity , faib tus naj npawb ntawm moles ntawm solute los ntawm lub ntim ntawm lub daws hauv litres. Yog tias koj tsis paub tus naj npawb ntawm moles ntawm solute tab sis koj paub qhov loj, pib los ntawm nrhiav molar mass ntawm lub solute, uas yog sib npaug rau tag nrho cov molar masses ntawm txhua yam nyob rau hauv lub daws ntxiv ua ke.

Dab tsi yog 1/10 dilution?

Piv txwv li, ua ib 1:10 dilution ntawm 1M NaCl tov, koj yuav sib tov ib "ib feem" ntawm 1M tov nrog cuaj "qhov" ntawm hnyav (tej zaum dej), rau tag nrho ntawm kaum "qhov." Yog li ntawd, 1:10 dilution txhais tau tias 1 feem + 9 feem ntawm dej (los yog lwm yam diluent).
