What happens when potassium iodide is mixed with copper sulphate?
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
What is the oxidation number of copper in copper iodide?
+1 in CuI or Cu2I2. +2 in CuI2.
Why you add ki in to cuso4.5h2o in copper iodide test?
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.
What is the correct name for this compound Cui2?
Copper II Iodide
What is formula for cupric iodide?
Cupric or copper II iodide is CuI2
What is the formula for the reaction between Potassium iodide and copper sulphate?
General: 2KI + CuSO4 ----> CuI2 + K2SO4 The CuI2 immediately decomposes to iodine and insoluble copper(I) iodide, releasing I2.:: 2 CuI2 → 2 CuI + I2
