A hydrophilic colloid , los yog hydrocolloid, yog txhais ua a colloid system uas colloid particle yog hydrophilic polymers dispersed nyob rau hauv dej. Piv txwv li, agar yog reversible hydrocolloid ntawm seaweed extract; Nws tuaj yeem muaj nyob hauv gel lossis kua hauv lub xeev thiab tuaj yeem hloov pauv ntawm cov xeev nrog cua sov lossis txias.
Tsis tas li ntawd, cov mis nyuj yog hydrophobic lossis hydrophilic colloid?
Txawm tias colloid hais tias tej zaum yuav me me uas cov dispersion zoo nkaus li zoo li nyob rau hauv ib lub microscope, lawv loj txaus kom tawg lub teeb zoo heev. Yog li ntawd, feem ntau colloids tshwm pos huab los yog opaque tshwj tsis yog tias lawv yog heev dilute. (Homogenized mis nyuj yog a colloid .)
Tsis tas li ntawd, dab tsi yog txhais los ntawm cov tshuaj colloidal? A colloidal tshuaj , qee zaus txheeb xyuas asa colloidal ncua kev kawm ntawv, yog ib tug sib tov nyob rau hauv uas cov tshuaj yog tsis tu ncua ncua nyob rau hauv ib tug kua. Txawm li cas los colloidal systems tuaj yeem tshwm sim hauv ib qho ntawm peb lub xeev tseem ceeb ntawm cov teeb meem roj, kua orsolid, a colloidal tshuaj unambiguously hais txog ib qho kua dej.
Kuj Paub, uas yog ib qho piv txwv ntawm ib tug colloid?
Colloids muaj nyob rau hauv lub neej txhua hnub. Ib txhia piv txwv xws li whipped cream, mayonnaise, mis nyuj, butter, gelatin, jelly, av nkos dej, plaster, xim iav, thiab ntawv. colloid muaj ob ntu: colloidal particles thiab dispersing nruab nrab. Ib qho colloid uas muaj cov khoom tawg nyob rau hauv cov pa roj yog hu ua pa luam yeeb.
Cov ntshav puas yog colloid?
Colloids muaj cov molecules loj insoluble, xws li gelatin; ntshav nws tus kheej yog ib colloid.
Pom zoo:
Dab tsi ua rau colloid ua colloid?
Nyob rau hauv chemistry, ib tug colloid yog ib tug sib tov nyob rau hauv uas ib yam khoom ntawm microscopically dispersed insoluble los yog soluble hais raug tshem tawm thoob plaws lwm yam khoom. Yuav kom tsim nyog raws li ib tug colloid, qhov sib tov yuav tsum yog ib qho uas tsis khom los yog yuav siv sij hawm ntev heev los khom nqi
Dab tsi yog qhov sib xyaw colloid?
Nyob rau hauv chemistry, ib tug colloid yog ib tug sib tov nyob rau hauv uas ib yam khoom ntawm microscopically dispersed insoluble los yog soluble hais raug tshem tawm thoob plaws lwm yam khoom
Dab tsi ua haujlwm pab pawg yog hydrophilic?
Cov pab pawg ua haujlwm hydrophilic muaj xws li pawg hydroxyl (ua rau muaj cawv txawm tias tseem pom muaj suab thaj, thiab lwm yam), pawg carbonyl (ua rau aldehydes thiab ketones), pawg carboxyl (ua rau carboxylic acids), pawg amino (piv txwv li, raws li pom hauv cov amino acids. ), sulfhydryl pawg (ua rau thiols, piv txwv li, raws li pom
Dab tsi ntawm colloid yog roj hmab?
Kev lag luam roj hmab: Latex yog cov tshuaj colloidal ntawm cov roj hmab uas tsis zoo. Los ntawm latex, roj hmab tuaj yeem tau los ntawm coagulation
Hydrophilic yooj yim yog dab tsi?
Hydrophilic txhais. Ib qho hydrophilic molecule los yog khoom yog attracted rau hauv dej. Dej yog ib tug polar molecule uas ua raws li cov kuab tshuaj, dissolving lwm polar thiab hydrophilic tshuaj. Nyob rau hauv biology, ntau yam tshuaj yog hydrophilic, uas tso cai rau lawv mus dispersed thoob plaws hauv lub cell los yog kab mob
