Copper sulfate (white) or -sulfate-pentahydrate (blue) will dissolve in water, so C and I2 can be filtered off. Concentrate the blue solution by boiling off the water (evaporate) and cool down and crystallise (blue crystals of CuSO4(H2O)5 ).
Iodine can be dissolved in ethanol 96% (tincturated) and Carbon is then filtered off. Evaporate ethanol at lowered pressure, but some I2 will also evaporate (purple vapor).
The filtered C (carbon black) can be dryed off the filter paper, it is not soluble.

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
How would you separate iodine crystals from mixture of iodine and sand?
we can separate them by sublimation as iodine sublimes on heating.
Copper and iodine reaction?
copper iodide
What is iodine solubility?
Iodine is highly soluble in water. It is also soluble in iodine solutions, chloroform, carbon tetrachloride and carbon disulphide among others.
In estimation of copper and nickel why we are using volumetric for copper and gravimetric for nickel seperately?
It is simply because they could not be found together!! copper can be estimated by treating with potassium iodide and iodine will be liberated in the reaction which is titrated against sodium thiosulphate during the reaction we will add sulphuric acid to prevent the hydrolysis of copper sulphate and we follow by, adding ammonia to neutralize sulphuric as it may hinder the reation between iodide and copper!! now again we will add acetic acid to neutralize ammonia.. and the indicator is added at the last because it will get absorbed with the iodine!! now atlast we add ammonium, thiocyanate to prevent the excess of iodine getting added to copper iodide. end point is disappearance of blue color.

Why do gold and copper conduct electricity better than carbon and iodine?
because they are metals
What elements are in CuCI3?
There are 3 elements in the chemical compound CuCI3. The 3 elements are: Copper (Cu), Carbon (C) and Iodine (I). In one molecule of this compound, there are 5 atoms: 1 copper atom, 1 carbon atom and three iodine atoms.
Which has the loest melting point iron copper carbon sulferoxygen nitregeon and iodine?
The lowest Melting point is for Nitrogen.
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
