Abubuwan Jiki da Sinadarai

Tsarin sinadarai shine CuI. Nauyin kwayoyin halitta shine 190.45. Farin kristal mai siffar sukari ko farin foda, mai guba. Matsakaicin dangi shine 5.62, wurin narkewa shine 605 ° C, wurin tafasa shine 1290 ° C. Barga zuwa haske da iska.Iodide mai laushishi ne kusan insoluble a cikin ruwa da ethanol, mai narkewa a cikin ruwa ammonia, tsarma hydrochloric acid, potassium iodide, potassium cyanide ko sodium thiosulfate bayani, za a iya c bazu ta hanyar mayar da hankali sulfuric acid da mayar da hankali nitric acid.

Cuprous iodide kusan ba zai iya narkewa a cikin ruwa (0.00042 g/L, 25 ° C) kuma ba shi da narkewa a cikin acid, amma zai iya ci gaba da daidaitawa tare da iodide don samar da ions [CuI2] madaidaiciya, waɗanda ke narkewa a cikin potassium iodide ko sodium iodide. A cikin bayani. Maganin da aka samu an narkar da shi don ba da hazo mai ɗorewa don haka an yi amfani da shi don tsarkake samfurin iodide na kofi.

Maganin acidic na jan karfe sulfate yana ƙara wuce gona da iri na potassium iodide ko kuma a ƙarƙashin motsawa, an ƙara gaurayawan bayani na potassium iodide da sodium thiosulfate a cikin ruwa zuwa wani bayani na jan karfe sulfate, don samun hazo na cuprous iodide. Bugu da kari ga general manufa amfani a matsayin reagents, da dai sauransu, amma kuma za a iya amfani da matsayin ikon-iodide thermal takarda conductive Layer abu, likita bakara, inji hali zazzabi wakili, amma kuma amfani da bincike na gano Mercury.

Guba: Tsawon lokaci da maimaita saduwa da jiki yana da illa, ya kamata a guje wa hulɗa da jiki kai tsaye. Ciwon yana cutar da jiki sosai.
