납(II) 요오드화물 C화학적 특성, 용도, 생산
물리적 성질
Yellow hexagonal crystals; density 6.16 g/cm3; melts at 402°C; vaporizes at 954°C; decomposes at 180°C when exposed to green light; slightly soluble in water (0.44 g/L at 0°C and 0.63 g/L at 20°C); Ksp 8.49x10-9 at 25°C; partially soluble in boiling water (4.1 g/L at 100°C); insoluble in ethanol; soluble in alkalis and alkali metal iodide solutions.용도
Lead(II) iodide is used as a detector material for high energy photons including x-rays and gamma rays. It is used in photography, printing, mosaic gold, and bronzing. It exhibits ferroelastic properties and has efficiency in stopping X-ray and gamma ray, which provides excellent environmental stability.제조 방법
Lead diiodide is prepared by mixing aqueous solutions of lead nitrate or lead acetate with an aqueous solution of potassium or sodium iodide or hydriodic acid, followed by crystallization. The product is purified by recrystallization.Pb2+(aq) + 2Iˉ (aq) → PbI2(s).
일반 설명
Lead iodide appears as a yellow crystalline solid. Insoluble in water and denser than water. Primary hazard is threat to the environment. Immediate steps should be taken to limit spread to the environment. Used in printing and photography, to seed clouds and other uses.공기와 물의 반응
Slightly water soluble.반응 프로필
Lead(II) iodide has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. Light sensitive위험도
Lead diiodide is toxic if ingested. The symptoms are those of lead poisoning.건강위험
Early symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often the ankles, is noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary tract. Pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact with eyes causes irritation.잠재적 노출
