m - nitroaniline Nws yog soluble nyob rau hauv ether, txawm tias lub aqueous txheej yooj yim ,vim a puag nyob puag hauv puag . Bases (eg., m - nitroaniline ,qus a puag vim hais tias nws yog ib tug proton txais) ua zoo them thaum reacted nrog ib tug acid, thiab no zoo them ion tam sim no yuav muab faib mus rau hauv lub aqueous txheej.

Hauv qhov no, dab tsi yog conjugate acid ntawm M nitroaniline?

Lub conjugate acid ntawm m-nitroaniline thiab cov conjugate puag ntawm sulfuric acid xav tias yuav nyob rau hauv lub aqueous tov. Qhov no yog xaus vim hais tias m-nitroaniline yog lub hauv paus, uas reacted nrog hydrosulfuric acid.

Tom qab ntawd, lo lus nug yog, vim li cas NaOH siv hauv kev rho tawm? Qhov tshwm sim no feem ntau yuav pom yog tias sodium bicarbonate yog siv rau cov rho tawm thiaj li yuav neutralize los yog tshem tawm acidic tebchaw. Cov tshuaj tiv thaiv them nyiaj carbon dioxide (CO2), uas yog ib qho roj ntawm ambient kub. Lub siab ua kom thawb qee cov roj thiab cov kua tawm.

Kuj Paub, yog Naphthalene yog lub hauv paus lossis kua qaub?

Cov hydrocarbon, ua nruab nrab, tsis yaj hauv lub hauv paus, nyob hauv qab hauv methylene chloride. Evaporation ntawm methylene chloride tawm ntawm naphthalene li crystals. Ces, koj ntxiv hydrogen chloride ua kom cov dej sodium benzoate hmoov kua qaub.

Puas yog benzoic acid soluble hauv 6m NaOH?

Benzoic acid tau pom tias yog soluble hauv dej thiab 1.0 M NaOH Txawm li cas los xij, thaum ntxiv 6.0 M HCl rau cov tshuaj no, benzoic acid ua insoluble.
