React a solution of Copper(II) sulfate with Sodium Iodide. It will produce Copper(II) Iodide and Sodium sulfate. This Copper(II) iodide, due to instability, spontaneously decomposes, producing Iodine and Copper(I) Iodide.
The Copper(I) iodide comes out as a yellowish brown precipitate. So the overall reaction seems to be:
2 CuSO4 + 4 NaI ----> 2 CuI + 2 Na2SO4 + I2

How is cuprous iodide formed from potassium iodide?
Cuprous iodide can be formed from potassium iodide by mixing a solution of copper(II) sulfate with potassium iodide. The reaction between the two compounds results in the precipitation of cuprous iodide, which is a solid compound. This solid can then be filtered and dried to obtain cuprous iodide.
Color of cuprous iodide?
Cuprous iodide typically appears as a white or pale yellow powder. It can also be described as a pale yellow solid.
Why do you prepare lead iodide from lead nitrate?
Lead iodide is prepared from lead nitrate because lead nitrate contains lead ions and nitrate ions that can react with iodide ions to form lead iodide. This reaction allows for the precipitation of lead iodide, which can then be isolated and collected.
Why alkyl iodide cannot be prepared directly?
Alkyl iodides cannot be prepared directly by iodination of alkanes because iodine is not a good enough electrophile to react with an alkane under typical reaction conditions. Alkyl iodides are usually prepared indirectly by reacting an alkyl halide with a soluble iodide salt in the presence of a mild oxidizing agent.
What is valency of cuprous?
"Cuprous" is an archaic term for what today is called copper (I), Cu+1.
How is cuprous iodide formed from potassium iodide?
Cuprous iodide can be formed from potassium iodide by mixing a solution of copper(II) sulfate with potassium iodide. The reaction between the two compounds results in the precipitation of cuprous iodide, which is a solid compound. This solid can then be filtered and dried to obtain cuprous iodide.
What is the formula of cuprous iodide?
CuI
Color of cuprous iodide?
Cuprous iodide typically appears as a white or pale yellow powder. It can also be described as a pale yellow solid.
What is a formula for cuprous iodide?
The chemical formula for cuprous iodide is CuI. It is composed of one copper atom (Cu) and one iodine atom (I), and it is a compound commonly used in organic synthesis and as a catalyst in various reactions.
What is the equation for sodium iodide and copper nitrate?
in aqueous medium ppts. of copper iodide are formed which are converted into cuprous iodide and free iodine in a short time. 2NaI + Cu(NO3)2 = CuI2 + 2NaNO3 2CuI2 = Cu2I2 + I2
Why do you prepare lead iodide from lead nitrate?
Lead iodide is prepared from lead nitrate because lead nitrate contains lead ions and nitrate ions that can react with iodide ions to form lead iodide. This reaction allows for the precipitation of lead iodide, which can then be isolated and collected.
What is the colour of cuprous sulphide?
The cuprous sulfide - Cu2S - is black.
How is iodine solution prepared?
Iodine solution is typically prepared by dissolving iodine crystals in a mixture of potassium iodide and distilled water. The potassium iodide acts as a stabilizer for the iodine. The final concentration of iodine in the solution can vary depending on its intended use.
Why alkyl iodide cannot be prepared directly?
Alkyl iodides cannot be prepared directly by iodination of alkanes because iodine is not a good enough electrophile to react with an alkane under typical reaction conditions. Alkyl iodides are usually prepared indirectly by reacting an alkyl halide with a soluble iodide salt in the presence of a mild oxidizing agent.
How many electrons does cuprous ion have?
a cuprous ion has 28 electrons.
What is the chemical formula for cuprous fluoride?
The chemical formula for cuprous fluoride is CuF.
What is the chemical formula for cuprous nitrate?
Actually, the answer Cu(NO3)2 is incorrect for cuprous nitrate. Cu(NO3)2 is in fact cupric nitrate. Cuprous nitrate is represented as CuNO3 alone.
