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 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
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).
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 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.
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 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.
Is there any reaction between copersulphate and KI?
Yes, a reaction will occur between copper(II) sulfate (copersulphate) and potassium iodide (KI) to form copper(II) iodide (CuI₂) and potassium sulfate (K₂SO₄). This is a double displacement reaction where the cations and anions switch partners.
Is there a precipitation reaction between potassium sulfate and strontium iodide?
Yes, a precipitation reaction occurs when potassium sulfate and strontium iodide are mixed. Potassium sulfate and strontium iodide react to form strontium sulfate, which is insoluble in water, leading to its precipitation as a solid.
What is the Reaction of iron sulphate with potassium iodide?
When iron sulfate reacts with potassium iodide, a double displacement reaction occurs where potassium sulfate and iron(II) iodide are formed. The balanced chemical equation for this reaction is FeSO4 + 2KI → FeI2 + K2SO4. This reaction is characterized by a color change from yellow (iron sulfate) to brown (iron(II) iodide).
How do you prepare a 5 percent potassium iodide solution?
To prepare a 5% potassium iodide solution, weigh 5 grams of potassium iodide and dissolve it in 100 mL of water. Stir until the potassium iodide is completely dissolved to achieve a 5% solution.
Which one is more dense a solution of potassium iodide or a mixture of toluene and naphthalene?
The solution of potassium iodide (if it is not extremely diluted) is more dense.
