Ib lub tshuab hluav taws xob yog ib qho hluav taws xob dawb hauv (solvated hauv) cov tshuaj, thiab yog qhov tsawg tshaj plaws anion. … Alkali hlau yaj nyob rau hauv cov kua ammonia muab tob xiav daws, uas ua hluav taws xob. Cov xim xiav ntawm cov tshuaj yog vim rau ammonia electrons, uas nqus lub zog hauv thaj tsam pom ntawm lub teeb.
Vim li cas ammoniacal tov ntawm alkali hlau xiav?
Alkali hlau yaj hauv cov kua ammonia muab cov kev daws teeb meem xiav sib sib zog nqus uas ua rau muaj xwm txheej. Cov xim xiav ntawm cov tshuaj yog vim yog ammonia electrons uas nqus lub zog hauv thaj tsam pom ntawm lub teeb.
Vim li cas cov tshuaj sodium hauv kua ammonia xiav?
Thaum sodium yog yaj hauv cov kua ammonia, cov tshuaj ntawm cov xim xiav sib sib zog nqus tau txais. … Hauv lwm lo lus, peb tuaj yeem hais tias cov xim xiav yog vim yog cov hluav taws xob solvated uas tau tso tawm los ntawm cov hlau sodium. Sodium ion yog solved nyob rau hauv cov tshuaj.
Koj ua li cas rau cov xim xiav ntawm cov tshuaj muab lub npe ntawm cov khoom tsim los ntawm kev khaws cov tshuaj rau qee lub sijhawm?
Muab lub npe ntawm cov khoom tsim los ntawm kev khaws cov tshuaj rau qee lub sijhawm. Cov tshuaj yog li muaj ammonia cations thiab ammoniated electrons. Thaum lub teeb poob rau ntawm cov tshuaj, cov ammonia electrons zoo siab los ntawm kev nqus lub zog sib xws rau lub teeb liab thiab lub teeb xa mus yog xiav.
Xim dab tsi yog ammoniakua?
Ammonia yog tsis muaj ximroj nrog cov ntxhiab tsw ntxhiab tsw. Nws yog qhov sib dua ntawm huab cua, nws qhov ceev yog 0.589 npaug ntawm huab cua. Nws yog yooj yim liquefied vim muaj zog hydrogen bonding ntawm molecules; cov kua boils ntawm −33.3 ° C (−27.94 ° F), thiab khov rau dawb crystals ntawm −77.7 ° C (−107.86 ° F).
