Aluminium chloride yog tsim los ntawm qhov loj me los ntawm exothermic tshuaj tiv thaiv ntawm aluminium hlau nrog tshuaj chlorine los yog hydrogen tshuaj chloride ntawm qhov kub ntawm 650 txog 750 ° C (1, 202 txog 1, 382 ° F). Aluminium chloride tuaj yeem tsim los ntawm ib qho kev hloov pauv tshuaj tiv thaiv nruab nrab ntawm tooj liab tshuaj chloride thiab aluminium hlau.

Ib sab ntawm no, hom tshuaj twg yog aluminium chloride?

Aluminium chloride yog cov tshuaj sib xyaw nrog cov tshuaj formula AlCl3 . Thaum muaj kab mob nrog cov tshuaj chloride, nws feem ntau pom cov xim daj piv rau cov xim dawb huv. Nws yog siv nyob rau hauv ntau yam tshuaj siv raws li ib tug Lewis puag, nrog anhydrous aluminium trichloride yog cov feem ntau siv Lewis acid.

Ib yam li ntawd, vim li cas aluminium chloride muaj nyob ua ib qho dimer? Yog li, ib qho dative lossis kev sib koom ua ke daim ntawv cog lus los ntawm Chlorine atom ntawm ib lub molecule mus rau Aluminium ntawm lwm yam. Yog li ntawd, cov molecules ua ke los yog dimerize kom txhua Aluminium atom muaj ib feem ntawm yim electrons nyob rau hauv nws lub plhaub sab nrauv.

Ib yam li ntawd, tib neeg nug, puas yog aluminium chloride soluble lossis insoluble?

Dej

Yuav ua li cas thaum Aluminium chloride reacts nrog dej?

Cov tshuaj tiv thaiv ntawm aluminium chloride nrog dej ua yeeb yam. Yog koj poob dej mus rau qhov khoom aluminium chloride , koj tau ua phem tshuaj tiv thaiv ua huab cua ntawm cov pa taws ntawm hydrogen tshuaj chloride gas. Tus nqi ntxiv ntawd rub cov electrons los ntawm dej molecules heev heev rau lub aluminium.
