Rau cov xab npum qhov tseem ceeb micelle concentration (CMC) yog \[{10^{ - 4}}] (min.) rau \[{10^{ - 3 }}] (max.) mol/L, tus nqi ntawm x yuav yog 4.
CMC ntawm xab npum yog dab tsi?
Los ntawm Wikipedia, phau ntawv qhia dawb. Nyob rau hauv colloidal thiab nto chemistry, lub tseem ceeb micelle concentration(CMC) yog txhais raws li cov concentration ntawm surfactants saum toj no uas micelles tsim thiab tag nrho cov surfactants ntxiv rau lub system yuav tsim micelles. CMC yog tus yam ntxwv tseem ceeb ntawm surfactant.
Qhov tseem ceeb micelle concentration siv li cas?
CMC (qhov tseem ceeb micelle concentration) yog qhov concentration ntawm cov surfactant nyob rau hauv ib theem, saum toj no uas sib sau ua ke ntawm surfactant molecules, thiaj li hu ua micelles, pib tsim. CMC yog tus yam ntxwv tseem ceeb rau surfactants.
Puas yog xab npum npuas micelle?
Thaum soap molecules tau ntxiv rau hauv dej, qee daim ntawv pawg, hu ua micelles, nyob rau hauv lub cev ntawm cov tshuaj uas cov nonpolar kawg yog nyob rau hauv nruab nrab ntawm pawg thiab lub polar. kawg yog nyob rau sab nraud. … Cov molecules saum npoo no yog ib qho tseem ceeb hauv kev ua xab npum npuas.
Puas tshuaj xab npum puas cuam tshuam nrog colloids ntawm CMC?
Cov colloids cuam tshuam feem ntau yog tsim los ntawm surfactants (surface active agents) xws li xab npum thiab tshuaj detergents. … Thaum yaj nyob rau hauv dej xab npum thiab xab npum molecules ua raws li ib tug electrolyte tab sis yog hais tias lawv concentration yog nce,Lawv cov molecules aggregate los tsim cov colloidal loj hais hu ua micelles.
