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 are the roles of iodine solution copper ii sulphate solution and Benedict's solution in food test?
Iodine solution is used to test for the presence of starch in food. Copper II sulfate solution is used to test for the presence of proteins in food. Benedict's solution is used to test for the presence of reducing sugars, such as glucose, in food.
What is the role of copper sulphate in estimation of copper by iodometry?
Copper sulfate is used to keep the copper ions in solution so that they can be titrated accurately. Iodometry involves the use of iodine to oxidize copper ions to cupric ions, which are then titrated with a standardized solution of thiosulfate to determine the amount of copper present. Copper sulfate ensures the copper ions remain in solution throughout the titration process.
Copper and iodine reaction?
When copper is added to iodine, a reaction occurs in which the copper displaces the iodine from its compound forming copper iodide. This reaction is a single displacement reaction where the more reactive copper replaces the less reactive iodine in the compound. The chemical equation for this reaction is Cu + I2 → CuI
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 chemical formula for carbon iodine?

Which has the loest melting point iron copper carbon sulferoxygen nitregeon and iodine?
Iodine has the lowest melting point among iron, copper, carbon, sulfur, oxygen, nitrogen, and iodine. Iodine is a nonmetal with a melting point of 113.7 degrees Celsius.
Why do gold and copper conduct electricity better than carbon and iodine?
because they are metals
