Pharmacy Dilution lej. Pharmacy Dilution Kev ua lej yog ib txheej txheem ntawm kev txo cov concentration ntawm kev daws los ntawm kev ntxiv cov kuab tshuaj ntxiv. Cov qauv piav qhia ntawm no tsuas yog siv rau lub hom phiaj ntawm diluting ib qho kev daws teeb meem los ntawm qhov feem pua siab dua mus rau qhov qis dua.

Yog li ntawd, dab tsi yog tshuaj dilution?

Dilution yog tus txheej txheem ntawm kev txo cov concentration ntawm cov kua nyob rau hauv ib qho kev daws, feem ntau tsuas yog los ntawm kev sib xyaw nrog ntau cov kuab tshuaj xws li ntxiv dej ntxiv rau kev daws. Cov diluted Cov tshuaj tseem muaj 10 grams ntsev (0.171 moles ntawm NaCl).

Tsis tas li ntawd, koj ua li cas dilution hauv lej? Cov naj npawb ntawm dilutions yog sib npaug rau tus naj npawb ntawm lub sij hawm dilution qhov tseem ceeb yuav muab faib los ntawm nws tus kheej kom sib npaug ntawm qhov pib concentration faib los ntawm qhov kawg concentration. Yog li nrog a dilution qhov tseem ceeb ntawm 10, 10 rau X lub zog yog sib npaug rau qhov pib concentration faib los ntawm qhov kawg concentration.

Dab tsi yog dilution factor siv rau?

Dilution factor yog ib tug sau feem ntau siv hauv kev soj ntsuam kev lag luam. Piv txwv li, hauv 1: 5 dilution ua 1:5, dilution yam , (hais lus li "1 txog 5" dilution ) entails combining 1 unit volume of solute (cov khoom yuav tsum diluted ) nrog (kwv yees) 4 units ntawm cov kuab tshuaj muab 5 units ntawm tag nrho cov ntim.

Koj ua li cas 1/10 dilution?

Piv txwv li, rau ua 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).
