Yog li ntawd, daim ntawv cog lus polarity yuav siab heev rau NaOH vim active polarization, ua NaOH ib tug polarsolute. Yog li ntawd, mus los ntawm lub hauv paus ntsiab lus- “Zoo li yaj zoo , polar NaOH yuav yooj yim dissolve nyob rau hauv polar H2O. Li no NaOH yuav heev solublein dej zoo li lwm yam polar solvents zoo li ethanol.
Hauv qhov no, NaOH puas soluble hauv dej?
Dej Ethanol Methanol
Ib yam li ntawd, vim li cas sodium hydroxide yaj hauv dej? Teb thiab piav qhia: Dissolving sodiumhydroxide hauv dej yog exothermic. Qhov no yog vim qhov sodium ions thiab hydroxyl ions muaj peev xwm cuam tshuam nrog cov dej
Ntawm no, yog NaOH soluble lossis insoluble hauv dej?
Nws yog heev soluble hauv dej , nrog alower solubility nyob rau hauv polar solvents xws li ethanol thiab methanol. NaOH yog insoluble nyob rau hauv ether thiab lwm yam uas tsis yog-polar solvents.
Yuav ua li cas sodium hydroxide reacts nrog dej?
Sodium hydroxide yuav teb nrog acids los tsim ib dej thiab ib qho ionic compound. Hauv hom no tshuaj tiv thaiv , cov hydroxide los ntawm sodium hydroxidereacts nrog hydrogen ion hauv cov kua qaub, ua dej.

Vim li cas LiF tsis soluble hauv dej?
Vim nws cov dej tsis muaj zog thiab ib nrab covalent thiab ib nrab ionic cim LiCl yog soluble hauv dej thiab acetone. Hauv Lithium fluoride lub lattice enthalpy yog siab heev vim qhov me me ntawm fluoride ions. Hauv qhov no, hydration enthalpy yog tsawg heev. Yog li, LiF yog insoluble hauv dej
Vim li cas phenol soluble hauv NaOH ntau dua li dej?
Phenol yog soluble hauv NaOH ntau dua hauv dej vim tias phenol yog acidic me ntsis. ua rau sodium phenoxide ntxiv ruaj khov. los tsim ib Hydronium ion (H30) phenol nrog sodium yog cov tshuaj tiv thaiv qeeb vim tias phenol yog cov kua qaub tsis muaj zog
Vim li cas BeF2 soluble hauv dej?
BeF2 yog soluble nyob rau hauv dej vim evolution ntawm loj hydration zog, thaum nws yog yaj nyob rau hauv dej, uas yog txaus txaus los mus kov yeej lub lattice zog ntawm lub Berylium Flouride, raws li rau ib tug compound yuav soluble nyob rau hauv dej, lub lattice zog ntawm lub compound yuav tsum tau. tsawg dua li hydrationenergy hloov zuj zus mus
Vim li cas cov dej hauv av silted suav hais tias yog lub cim ntawm kev tsim cov dab dej?
Sinkholes yog txhua yam hais txog dej. Dej yaj cov ntxhia hauv pob zeb, tawm hauv seem thiab qhib qhov chaw hauv pob zeb. Dej ntxuav cov av thiab cov seem ntawm cov voids hauv pob zeb. Kev txo qis ntawm cov dej hauv av tuaj yeem ua rau poob ntawm kev txhawb nqa rau cov khoom muag hauv cov pob zeb uas tuaj yeem ua rau tawg
Vim li cas HCl soluble hauv dej?
HCl yaj hauv dej (H2O). Cov hydrogenions (protons) hnov mob nrog dej los tsim hydronium ions (H3O) thiab cov chloride ions yog dawb hauv kev daws. H-Cl covalent bond ispolar. Nyob rau hauv ib tug polar daim ntawv cog lus cov electron khub sib koom ntawm ob atomsis attracted ntau dua electronegative atom
