Cov ntsiab lus ntawm cov tshuaj tuaj yeem qhia ntau ntau yam xws li molarity, mole fraction, thiab lwm yam. ntawm kev daws. Chav tsev ntawm molarity yog molar(M) los yog moles/L.
Peb txoj hauv kev uas qhov kev daws teeb meem tuaj yeem qhia tau yog dab tsi?
Chemists tuaj yeem nthuav qhia ntau yam hauv ntau txoj hauv kev suav nrog: Molarity (M), Qhov ib lab (ppm), % muaj pes tsawg leeg, lossis gram / Liter (g / L).
Yuav ua li cas yog qhov concentration ntawm cov tshuaj qhia hauv hoob 9?
Cov tshuaj uas muaj cov kuab tshuaj ntau yog hu ua Concentrated Solution. Qhov concentration ntawm cov tshuaj yog txhais raws li hnyav ntawm cov kua hauv grams tam sim no hauv 100 g ntawm cov tshuaj. … Saturated tov muaj ntau npaum li cas ntawm solute uas yuav yaj nyob rau hauv nws ntawm ib tug muab kub.
Vim li cas peb thiaj li yuav tsum tau nthuav tawm cov ntsiab lus ntawm kev daws teeb meem ntau?
Cov ntsiab lus concentrated thiab dilute tsuas yog cov lus txheeb ze. Ib qho tshuaj muaj zog muaj ntau dua nyob hauv nws dua li cov tshuaj dilute; Txawm li cas los xij, qhov no tsis qhia txog qhov tseeb npaum li cas ntawm solute tam sim no. Yog li ntawd, peb xav tau ntau qhov tseeb, ntau txoj hauv kev ntawm kev nthuav qhia concentration.
Chav tsev twg siv tau los qhia txog qhov kev daws teeb meem?
Txoj kev xav(M) qhia txog tus naj npawb ntawm moles ntawm cov kuab tshuaj ib liter ntawm kev daws (moles / Liter) thiab yog ib qho ntawm feem ntau units siv los ntsuas qhov concentration ntawm cov tshuaj. Molarity yuav siv tau los xam qhov ntim ntawm cov kuab tshuaj los yog tus nqi ntawm solute.
