Qab Zib dissolves yooj yim hauv dej thiab ua oildos tsis yog.
Ib yam li ntawd, nws raug nug, puas qab zib yaj hauv dab tsi?
Thaum twg qab zib yaj Nyob rau hauv dej, cov tsis muaj zog bonds ntawm ib tug neeg sucrose molecules yog tawg, thiab cov C12H22O11 molecules raug tso tawm rau hauv cov tshuaj. Qab zib dissolves nyob rau hauv dej vim hais tias lub zog yog muab tawm thaum lub me ntsis polar sucrose molecules formintermolecular bonds nrog polar dej molecules.
Tom qab, lo lus nug yog, vim li cas cov piam thaj tsis yaj hauv cov roj? Vim dej yog polar thiab roj yog nonpolar, lawv cov molecules yog tsis yog attracted rau ib leeg. Cov molecules ntawm polar solvent zoo li dej yog attracted rau lwm cov polar molecules, xws li cov qab zib . Qhov no piav qhia vim li cas qab zib hais tau siab heev solubility hauv dej.
Kuj nug, ua li cas thaum qab zib thiab dej sib tov?
cov molecules tau tawg mus rau hauv atoms thiab dispersed nyob rau hauv dej . Cov qab zib molecules tsis tuaj yeem ploj mus tab sis lawv tuaj yeem tawg mus rau hauv dej . Lawv tseem yuav yog qab zib molecules tsuas yog tsis txuas rau lwm yam molecules ntawm qab zib . tus dej thiab cov qab zib particle yuav sib tov ua ke thiab tsim ib yam tshiab.
Puas qab zib yaj hauv cov roj?
Roj molecules tsis polar ces lawv ua tsis tau yaj yog coloring los yog qab zib.

Puas yog cawv yog sib tov lossis sib xyaw?
Technically, cawv yog lub npe ntawm cov khoom siv hauv chav kawm uas muaj ib lossis ob peb pawg hydroxyl.Anazeotrope [] yog sib xyaw ntawm ob lossis ntau dua cov kua dej uas tsis tuaj yeem hloov pauv los ntawm kev distillation yooj yim. Lwm cov khoom lag luam, xws li isopropanol thiab acetone
Puas yog kev sib xyaw cov khoom xyaw rau lub ncuav mog qab zib yog tshuaj lom neeg?
Cov ntaub ntawv yooj yim ntawm kev sib cais thiab sib xyaw yog suav tias yog kev hloov pauv ntawm lub cev, tab sis kev sib xyaw cov khoom xyaw ntawm lub ncuav mog qab zib tsis yog ib qho kev sib xyaw yooj yim. Kev hloov tshuaj pib tshwm sim thaum cov khoom xyaw sib xyaw, tsim cov tshuaj tshiab
Yuav ua li cas tshwm sim thaum aqueous tov ntawm sodium sulphate thiab barium chloride sib tov?
Thaum cov tshuaj aqueous ntawm sodium sulphate reacts nrog ib tug aqueous tov ntawm barium chloride, precipitate ntawm barium sulphate yog tsim thiab tom qab cov tshuaj tiv thaiv tshwm sim. ii. Yog hais tias cov reactants nyob rau hauv lub cev muaj zog, ces cov tshuaj tiv thaiv yuav tsis tshwm sim. Nws yog ib qho kev hloov pauv ob npaug nrog rau nag lossis daus
Dab tsi ntawm kev sib tov yog qab zib thiab ntsev?
Kev sib xyaw ua ke ntawm ob lub khib nyiab, tsis muaj melting lawv ua ke, feem ntau ua rau muaj kev sib xyaw ua ke.Piv txwv li cov xuab zeb thiab qab zib, ntsev thiab gravel, cov khoom ntim khoom, thiab lub thawv khoom ua si uas muaj cov khoom ua si. Mixturesin ob lossis ntau theem yog heterogeneousmixtures
Dab tsi tshwm sim thaum qab zib thiab ntsev sib tov hauv dej?
Thaum koj dissolve qab zib los yog ntsev hauv aliquid-hais, dej-dab tsi tshwm sim yog tias cov piam thaj molecules txav kom haum lawv tus kheej ntawm lawv cov dej hauv ib khob los yog beaker. Ib qho kuab tshuaj, xws li qab zib, yaj hauv cov kuab tshuaj, xws li dej, ua rau cov kua ua kua
