Nws yog vim nws muaj peev xwm tsim hydrogen bonding nrog dej molecules Txawm li cas los xij qhov loj ntawm phenol molecule yog phenyl pawg uas tsis yog polar thiab li no nws solubility yog txwv nyob rau hauv dej. Txawm li cas los xij, qhov polarity ntawm qhov no kuj nce ntxiv hauv phenoxide ion. … Li no phenol yog sparingly soluble hauv NaHCO3
Vim li cas phenols tsawg soluble hauv dej dua li lwm yam cawv?
Phenols: Phenols kuj tsim hydrogen bonds nrog dej thiab yog li soluble hauv dej. Txawm li cas los xij, qhov solubility ntawm phenols qis dua li ntawm cov cawv vim muaj cov hydrocarbon loj dua (benzene nplhaib).
YVim li cas Phenol thiaj yaj hauv dej?
Phenol yog me ntsis soluble hauv dej vim nws muaj peev xwm tsim hydrogen bonds nrog dej.
Vim li cas Phenol yog ib nrab miscible hauv dej?
Teb: (i) Phenol yog ib nrab soluble vim nws muaj polar -OH pawg tab sis tsis yog polar, muaj ntxhiab phenyl pawg. (ii) Toluene yog insoluble vim nws tsis yog-polar thaum dej yog polar. (iii) Formic acid yog soluble heev vim nws tuaj yeem tsim hydrogen bonds nrog dej.
YPuas yog phenol soluble hauv dej?
phenol is tsis soluble hauv dej.

Leej twg yog ethanol soluble hauv dej?
Ethanol yog ib qho dej cawv uas yog soluble hauv dej Qhov no yog vim yog pawg hydroxyl (−OH) hauv ethanol uas tuaj yeem tsim cov hydrogen bonds nrog dej (H2O.) cov molecules. Hydrogen bonding txhais tau hais tias kev sib cuam tshuam ntawm dipole-dipole ntawm ob lub molecules thiab nws tuaj yeem ua intramolecular thiab intermolecular .
Vim li cas cov dej phwj hauv lub Hoobkas ua rau muaj kev phom sij rau cov kab mob hauv dej?
Cov kab mob paug paug los ntawm cov dej phwj tuaj feem ntau ua rau nyob rau hauv cov kab mob sib kisuas kis tau cov dej hauv dej thiab cov neeg hauv av los ntawm dej haus. Organic teeb meem thiab cov as-ham ua rau muaj kev nce hauv aerobic algae thiab depletes oxygen los ntawm cov dej.
Vim li cas cov chav dej da dej rov qab hauv Australia?
Vim kev sib hloov ntawm lub ntiaj teb, cov Coriolis nyhuv Coriolis nyhuv Lub Coriolis quab yuam ua nyob rau hauv ib qho kev taw qhia perpendicular mus rau lub axis rotationthiab mus rau qhov ceev ntawm lub cev nyob rau hauv lub rotating. thav duab thiab yog proportional rau cov khoom ceev nyob rau hauv lub rotating thav duab (ntau precisely, rau cov feem ntawm nws tshaj tawm uas yog perpendicular rau lub axis ntawm kev sib hloov).
Cov piam thaj hauv dej li cas soluble?
Koj yuav tsum tau pom cov suab thaj muaj qhov solubility siab tshaj plaws ntawm tag nrho koj cov tshuaj ntsuam xyuas ( li 200 grams ib 100 milliliters dej) ua raws li Epsom ntsev (li 115 grams / 100 milliliters.) rooj ntsev (li 35 grams / 100 milliliters) thiab ci dej qab zib (yuav luag 10 grams / 100 milliliters) .
Puas yog dej sodium soluble lossis rog soluble?
Vitamins yog cais raws li cov rog soluble (vitamin A, D, E thiab K) los yog dej soluble (vitamin B thiab C). Qhov sib txawv ntawm ob pawg no tseem ceeb heev. Nws txiav txim siab seb txhua cov vitamin ua li cas hauv lub cev. Cov vitamins muaj roj soluble yog soluble hauv lipids (fas) .
