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 else can I help you with?
What colour is copper iodide and potassium sulphate?
Potassium sulfate would be colorless; copper iodide is probably blue or green (I don't know which off the top of my head, but copper salts are generally either blue or green).
What happens when Potassium Iodide is added in Copper Chloride?
2K(I) + CuCl2 => 2KCl + Cu(I)2 The (I) is iodide, because the capital I and lowercase l look the same. This is a double replacement reaction, where copper (II) iodide comes out of solution, because it's not soluble, assuming that both of those are in solution.
What Copper sulfate solution and potassium iodide?
When copper sulfate solution is mixed with potassium iodide, a solid precipitate of copper iodide is formed, while potassium sulfate remains in solution. This reaction is a double displacement reaction. The balanced chemical equation is CuSO4 + 2KI → CuI2 + K2SO4.
How is cuprous iodide prepared?
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
Is copper iodide soluble?
Copper iodide is sparingly soluble in water, meaning it dissolves only to a small extent. It is more soluble in concentrated aqueous ammonia and potassium iodide solutions.
Add an excess of potassium iodide to copper sulphate solution how much is excess?
The amount of excess potassium iodide depends on the stoichiometry of the reaction between potassium iodide and copper sulfate. One equivalent of potassium iodide is needed to react with one equivalent of copper sulfate. Excess potassium iodide would be any amount added beyond this stoichiometric ratio.
What colour is copper iodide and potassium sulphate?
Potassium sulfate would be colorless; copper iodide is probably blue or green (I don't know which off the top of my head, but copper salts are generally either blue or green).

What is the formula for the reaction between Potassium iodide and copper sulphate?
The balanced chemical equation for the reaction between potassium iodide and copper sulfate is: 2KI(aq) + CuSO4(aq) → CuI2(s) + K2SO4(aq). In this reaction, a double displacement occurs leading to the formation of insoluble copper iodide and soluble potassium sulfate.
What Copper sulfate solution and potassium iodide?
When copper sulfate solution is mixed with potassium iodide, a solid precipitate of copper iodide is formed, while potassium sulfate remains in solution. This reaction is a double displacement reaction. The balanced chemical equation is CuSO4 + 2KI → CuI2 + K2SO4.
Iron plus potassium iodide?
When iron reacts with potassium iodide, it forms potassium iodide. The reaction can be written as 2Fe + 2KI → 2K + 2FeI. Potassium iodide is a salt and is commonly used as a nutritional supplement.

Is copper iodide soluble?
Copper iodide is sparingly soluble in water, meaning it dissolves only to a small extent. It is more soluble in concentrated aqueous ammonia and potassium iodide solutions.
What happens when potassium iodide react with lead nitrate?
When potassium iodide reacts with lead nitrate, a double displacement reaction occurs. The potassium ion and the lead ion switch places to form potassium nitrate and lead iodide. This reaction results in the formation of a yellow precipitate of lead iodide.
What happens if silver iodide is combined with potassium nitrate?
Silver iodide (AgI), a precipitate insoluble in water, don't react with potassium nitrate.
What result of Potassium iodide Ammonium sulfide?
Nothing happens
