Sol, nyob rau hauv lub cev chemistry, ib tug colloid (tag nrho cov zoo heev hais dispersed nyob rau hauv ib tug nruam nruab nrab) nyob rau hauv uas cov hais yog cov khoom thiab cov dispersion nruab nrab yog kua. Yog hais tias qhov nruab nrab dispersion yog dej, lub colloid yuav hu ua hydrosol; thiab yog huab cua, aerosol.
Zoo txhais li cas hauv colloid?
Ib tug yog ib tug colloid ua tawm ntawm cov khoom nyob rau hauv ib tug nruam kua nruab nrab. Sols yog qhov ruaj khov heev thiab qhia cov nyhuv Tyndall. Piv txwv xws li ntshav, pigmented ink, cell kua, xim, antacids thiab av nkos. Artificial sols tej zaum yuav raug npaj los ntawm dispersion los yog condensation.
YPuas yog sol thiab colloids tib yam?
Colloid yog ib qho sib xyaw uas ib yam khoom tawg mus rau lwm yam khoom. … Sol yog ib hom colloid nyob rau hauv uas dispersed theem yog khoom thiab dispersed nruab nrab yog kua. Nws yog cov kua hauv lub xeev ntawm cov tshuaj colloidal.
sol thiab nws hom yog dab tsi?
Ib tus sol yog hom colloid uas cov khoom tau raug tshem tawm hauv cov kua. Cov particles nyob rau hauv ib tug sol yog tsawg heev. Cov tshuaj colloidal qhia cov nyhuv Tyndall thiab ruaj khov. Sols tuaj yeem npaj los ntawm kev sib xyaw ua ke los yog dispersion. Ntxiv tus neeg sawv cev dispersing tuaj yeem ua rau muaj kev ruaj ntseg ntawm sol.
YYuav ua li cas hom colloid yog Sol thiab gel?
Teb tiav:
- Sol thiab gel yog ob hom colloids. Txhua qhov sib xyaw heterogenous uas muaj cov khoom sib npaug sib npaug ntawm qhov nruab nrab hu uadispersion nruab nrab. Txoj kab uas hla ntawm cov khoom ntawm colloids feem ntau yog 1nm txog 1000nm.
