Phenol yog ntau soluble hauv NaOH dua hauv dej yog vim phenol yog me ntsis acidic. ua rau sodium phenoxide ruaj khov. los tsim ib Hydronium ion (H30). phenol nrog sodium yog cov tshuaj tiv thaiv qeeb vim phenol yog ib tug tsis muaj zog acid.

Ntawm no, vim li cas phenols tsawg soluble hauv dej?

Phenol kuj yog soluble nyob rau hauv dej mus rau qee qhov. Nws yog vim nws muaj peev xwm tsim hydrogen bonding nrog dej molecules. Txawm li cas los lub loj ib feem ntawm phenol molecule yog phenyl pawg uas tsis yog polar thiab li no nws solubility yog txwv nyob rau hauv dej.

Tsis tas li ntawd, vim li cas phenol soluble hauv dej ntau dua li benzene? Yog vim li cas rau tus nqi siab dua rau phenol yog inpart vim mus tas li dipole-dipole attractions vim theelectronegativity ntawm cov pa oxygen - tab sis feem ntau yog vim hydrogenbonding. Phenol yog nruab nrab soluble nyob rau hauv dej - txog 8 g phenol yuav yaj hauv 100 g ntawm dej.

Kuj tseem paub yog, hom tshuaj tiv thaiv dab tsi piav qhia txog kev solubility ntawm phenol hauv sodium hydroxide?

Txhua yam nyob rau hauv nruab nrab yuav qhia raws li ib co ntxoov ntxoo ntawm "nruj". Phenol reacts nrog sodium hydroxide tshuaj kom muab cov xim tsis muaj xim muaj sodium phenoxide. Hauv no tshuaj tiv thaiv , cov hydrogen ion tau raug tshem tawm los ntawm qhov yooj yim heev hydroxide ion hauv sodiumhydroxide daws.

Dab tsi cov ntsiab lus yog soluble hauv NaOH?

Dej Ethanol Methanol
