Ilana kemikali jẹ CuI. Iwọn molikula jẹ 190.45. Kirisita onigun funfun tabi lulú funfun, majele. Iwuwo ibatan jẹ 5.62, aaye yo jẹ 605 °C, aaye farabale jẹ 1290 °C. Idurosinsin si imọlẹ ati afẹfẹ.Cuprous iodidejẹ fere insoluble ninu omi ati ethanol, tiotuka ninu omi amonia, dilute hydrochloric acid, potasiomu iodide, potasiomu cyanide tabi soda thiosulfate ojutu, le ti wa ni c decomposed nipasẹ oncentrated sulfuric acid ati ogidi nitric acid.
Cuprous iodide fẹrẹ jẹ insoluble ninu omi (0.00042 g/L, 25 ° C) ati pe ko ṣee ṣe ninu acid, ṣugbọn o le tẹsiwaju lati ipoidojuko pẹlu iodide lati ṣe awọn ions laini [CuI2], eyiti o jẹ tiotuka ninu potasiomu iodide tabi sodium iodide. Ni ojutu. Ojutu Abajade ti fomi po lati fun aropin iodide cuprous ati nitorinaa a lo lati sọ ayẹwo iodide cuprous di mimọ.
Ojutu ekikan ti imi-ọjọ imi-ọjọ Ejò jẹ afikun potasiomu iodide tabi labẹ saropo, ojutu adalu ti potasiomu iodide ati iṣuu soda thiosulfate ni a ṣafikun dropwise si ojutu kan ti imi-ọjọ imi-ọjọ, lati gba ojoriro ti iodide cuprous. Ni afikun si gbogbo idi lilo bi reagents, ati be be lo, sugbon tun le ṣee lo bi agbara-iodide gbona iwe conductive Layer ohun elo, egbogi sterilization, darí ti nso otutu oluranlowo, sugbon tun lo fun igbekale ti wa kakiri Makiuri.
