商品介绍

Occurs in nature as the mineral iodargirita. Birefringent transparent lemon-yellow hexagonal prisms or birefringent red octahedrons. m.p. = 560 ° C (with decomposition).

Diamagnetic. Slightly soluble in water, soluble in concentrated hydriodic acid, alkali metal iodides. Under the influence of light is decomposing into constituent elements of silver iodide. Molar conductivity at infinite dilution at 25 ° C is equal to 138.7 Cm.sm2/mol. Prepared in the lab (in the dark) treating the solution with a solution of AgNO3 HI or an alkali metal iodide, by direct interaction with iodine vapor, metallic silver chloride, silver bromide or by heating action on the HI cold metallic silver. Very often is used for light-sensitive films and other industry related production.
