Sep 19, 2018

Chromium trichloride feem ntau yog xim liab monoclinic siv lead ua, chromium ion yog nyob rau hauv octahedral chaw tsim los ntawm chloride ion nyob rau hauv hexahedron. Qhov sib npaug txheeb ze yog 1.76g / cm3, lub pob zeb tawg yog 83 degrees, thiab qhov ceev yog 2.87.

Nws yog ib qho yooj yim rau deliquescence, soluble nyob rau hauv dej, liab doog nyob rau hauv dilute daws, ntsuab nyob rau hauv concentrated daws, thiab pH nyob rau hauv 0.2 mol / L daws yog 2.4. Soluble nyob rau hauv cawv, me ntsis soluble nyob rau hauv acetone, yuav luag insoluble nyob rau hauv ether.

Khaws ntawm chav sov thiab cua txias kom tsis txhob muaj teeb, qhib tua hluav taws thiab kub. Sublimate ntawm 950 degrees Celsius thiab decompose ntawm 1300 degree Celsius.
