Product introduction:
Descriptors: gray or brownish yellow powder. Insoluble in ethanol, soluble in sulfuric acid, hydrochloric acid, ammonia and potassium iodide, sodium thiosulfate and sodium cyanide in aqueous solution. Under the action of light, easy to decompose.
Cuprous iodide almost insoluble in water (0.00042 g/L, 25 ° C), also does not dissolve in acid, but can continue coordination and iodine ions, generate linear CuI2 ion, which dissolved in potassium iodide and sodium iodide solution. Get the solution of the dilution and cuprous iodide precipitation, therefore can be used in the purification of samples of cuprous iodide.
Properties: white crystalline or gray powder, see light to brown. Insoluble in water and ethanol. Soluble in 75% sulfuric acid and hydrochloric acid, soluble in ammonia, potassium iodide. Generate cuprous oxide and sodium hydroxide.
