Txoj kev Carius halogen hauv kev tshuaj ntsuam chemistry yog ib txoj hauv kev rau kev txiav txim siab ntau ntawm halogens hauv cov tshuaj lom neeg. Ib qho paub ntau ntawm cov organic compound yog rhuab nrog fuming nitric acid nyob rau hauv lub xub ntiag ntawm silver nitrate muaj nyob rau hauv ib lub iav nyuaj raj hu ua carius raj, nyob rau hauv lub cub tawg.
Puas halogens tau kwv yees los ntawm txoj kev Carius?
Kev kwv yees ntawm halogens: Halogens kwv yees los ntawm cov txheej txheem hu ua Carius method. Nyob rau hauv txoj kev no ib tug paub kom muaj nuj nqis ntawm cov organic compound yog reacted nrog fuming nitric acid nyob rau hauv lub xub ntiag ntawmnyiaj nitrate. Cov pa roj carbon thiab hydrogen tau oxidized thiab halogen hloov mus rau nyiaj halide.
Txoj kev twg yog siv rau kev kwv yees halogen?
Carius method yog siv rau kev kwv yees ntawm halogen.
Cov khoom twg yog tsim los ntawm txoj kev Carius?
Nyob rau hauv txoj kev Carius, ib tug paub loj ntawm cov compound yog rhuab nrog concentrated nitric acid nyob rau hauv lub xub ntiag ntawm silver nitrate nyob rau hauv ib tug nyuaj iav raj. Lub raj iav tawv yog lub npe hu ua Carius raj. Carbon dioxide thiab dej yog tsim los ntawm oxidation ntawm carbon thiab hydrogen feem.
Yuav ua li cas reagent siv rau hauv kev txheeb xyuas qhov ntsuas ntawm halogen?
Test for Halogen:
Sodium halide rho tawm nrog dej tuaj yeem txheeb xyuas tau yooj yim los ntawm kev ntxiv silver nitrate tov tom qab acidifying nrog dil. HNO3. Yog tias muaj cov tshuaj chlorine, ib qho dawb curdy precipitate soluble hauv ammonium hydroxide tov yog tsim.
