Koj ua tau paub phenol vim: e yog ncaj insoluble nyob rau hauv dej . Nws reacts withsodium hydroxide tov kom muab cov xim tsis muaj xim (thiab yog li yuav tsum yog acidic). Nws tsis tsim cov pa roj carbon dioxide nrog sodium carbonate lossis hydrogencarbonate cov ntsiab lus (thiab yog li yuav tsum yog cov acidic tsis muaj zog).
Hauv qhov no, ua li cas thaum phenol hnov mob nrog dej?
Phenol yog me ntsis soluble hauv dej vim nws muaj peev xwm tsim hydrogen bonds nrog rau dej . Nplooj ntawv no piav qhia vim li cas phenol yog ib tug tsis muaj zog acidand saib nws cov tshuaj tiv thaiv (los yog qee zaum, tsis muaj tshuaj tiv thaiv ) nrog puag thiab nrog sodium hlau.
Qhov thib ob, yog phenol A acid zog dua dej? Phenol yog acidic ntau dua li dej vim poob H^+ dej tsim hydroxide ion (OH^-) thiab phenol phenoxide ion (C6H5O^-).
Ntawm no, phenol puas tuaj yeem yaj hauv dej?
Dej
Puas yuav phenol react nrog NaOH?
Kev tshwm sim Nrog Base vim phenols yog cov tsis muaj zog acids, lawv yuav tawm tsam nrog bases. Yog phenol yog reacted nrog NaOH (lub hauv paus muaj zog), nws yog kiag li hloov mus rau phenoxide ion, uas yog soluble nyob rau hauv dej vim nws yog them. Phenol nws tus kheej yog tsis heev soluble nyob rau hauv dej.

Yuav mg react nrog dilute sulfuric acid?
Magnesium hlau yaj yooj yim hauv dilute sulfuric acid los tsim cov kev daws teeb meem uas muaj cov dej hauv dej Mg (II) ion ua ke nrog hydrogen gas, H2. Kev sib raug zoo nrog lwm cov kua qaub xws li hydrochloric acid kuj muab cov dej hauv Mg (II) ion
Puas yog Aluminium React nrog nitric acid?
Qhov tseeb, nitric acid tsis hnov mob nrog txhuas. Nws yuav hnov tsuas yog thaum nitric dilute heev. Vim hais tias thaum txhuas los rau hauv kev sib cuag nrog nitric acid, ib txheej impervious ntawm txhuas oxide yog tsim. Yog li no txheej tiv thaiv thiab tiv thaiv ntxiv cov tshuaj tiv thaiv
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Puas yog carboxylic acid react nrog 2 4 Dnph?
2,4-DNPH tsis hnov mob nrog amides, esters lossis carboxylic acids. Raws li qhia hauv qab no rau cov ntaub ntawv ntawm ester, ib qho ntxiv resonance qauv tuaj yeem kos rau 3 hom kev sib xyaw ua ke piv rau ketone
Dab tsi yog ammonium hydroxide react nrog?
Ammonium hydroxide reacts nrog tooj liab (II) chloride tsim cov khoom tooj liab (II) hydroxide, uas yog precipitate (ib qho khoom), thiab ammonium chloride, uas yog ntsev. Ammonium chloride, nyob rau hauv lem, tuaj yeem hnov mob nrog sodium hydroxide los ua ammonia gas (NH3), dej, thiab sodium chloride
