Cupric or copper II iodide is CuI2
Copper II Iodide
If you mean CuI2 it is copper II iodide.
In the laboratory, copper(I) Iodide is prepared by simply mixing an aqueous solutions of potassium iodide and a soluble copper(II) salt such copper sulphate. : :: Cu2+ + 2I− → CuI2 The CuI2 immediately decomposes to iodine and insoluble copper(I) iodide, releasing I2. : :: 2 CuI2 → 2 CuI + I2
KI reacts with Cu2+ ions and then the CuI2 formed dicomposes to give insoluble CuI salt and I2. The iodine makes the solution brown. Cu2+ + 2I− → CuI2 2 CuI2 → 2 CuI + I2 Sodium thiosulfate can be added to this mixture. It reacts with the iodine giving a white ppt in a colourless solution.
The chemical formula for copper (I) iodide is CuI, and for copper (II) iodide is CuI2. Copper (I) iodide is the more common of the two.
Formula: CuI2
CuI2
Cupric or copper II iodide is CuI2
General: 2KI + CuSO4 ----> CuI2 + K2SO4 The CuI2 immediately decomposes to iodine and insoluble copper(I) iodide, releasing I2.:: 2 CuI2 → 2 CuI + I2
