Cov lus qhia luv luv:
Cerium (III) hydrate
Molecular cov mis: CE2 (c2o4) 3
Molecular hnyav: 544.29
Cas tsis muaj. :15750-47-7
Zog: cov hmoov dawb crystalline, tsw ntxhiab thiab tsis tau. Nws cov ntsev anhydrous ntsev yog monoclinic cont contotals. Thaum qhuav hauv lub tshuab nqus tsev, lub ntom ntom yog 2.2413g / cm3. 9 Dej ntsev poob los 8 molecules ntawm cov siv lead ua ntawm 110 ° C. Insoluble hauv dej, ethanol, ether, le hydroxide, oxalic acid daws, alkali daws; soluble suluguric acid, tsis tshua soluble hauv dej, insoluble hauv dilute acid, tab sis soluble thaum rhuab. Thaum rhuab hauv hydrogen huab cua, 10-dej ntsev hloov ntawm xim av rau xim dub.
Siv: siv ua tshuaj lom neeg siv tshuaj thiab npaj lwm cov ntsev cerium. Nws muaj qhov cuam tshuam ntawm kev tawm tsam lub plab, antiemetic thiab sedative, tab sis nws yog cov tshuaj muaj zog. Mas siv nyob rau hauv kev lag luam kws tshuaj ntsuam thiab sib cais ntawm cerium hlau hais.
