Taw qhia rau txoj kev tshuaj xyuas ntawm nitrogen purity
Dec 11, 2022
Rau qhov purity ntawm nitrogen, peb yuav tsum tau xyuas nws ua ntej siv, vim hais tias nitrogen ntawm txawv purity muaj ntau yam ntxwv los yog siv. Yog li, peb tuaj yeem ua li cas thaum kuaj xyuas?
Txhawm rau kuaj qhov purity ntawm nitrogen, ib txoj hauv kev yog muab cov hlau nplaum (Mg) rau hauv lub tog raj kheej uas muaj cov roj nitrogen, cov magnesium sawb (Mg) yuav txuas ntxiv hlawv, tshem tawm cov tshauv (dawb hmoov Mg3N2), thiab Ntxiv Ib qho me me ntawm cov dej kub ua rau muaj roj (ammonia) uas hloov cov ntawv ntub dej liab litmus xiav Yog tias daim ntawv litmus hloov xim, ces nws tsis tuaj yeem piav qhia tias nws yog nitrogen.
Lwm txoj hauv kev yog hlawv magnesium hauv nitrogen. Yog hais tias lub teeb daj (magnesium nitride), cov roj yog nitrogen.
