What happens when potassium iodide is mixed with copper sulphate?
When potassium iodide is mixed with copper sulfate, a double displacement reaction occurs. Copper iodide and potassium sulfate are formed as products. The copper iodide produced is insoluble and will precipitate out of the solution.
How is cuprous iodide prepared?
Cuprous iodide is typically prepared by reacting a solution of copper(I) chloride with potassium iodide. The copper(I) chloride reacts with potassium iodide to form cuprous iodide, which can then be isolated through filtration and washing with water. The resulting cuprous iodide is a pale yellow solid.
What colour is copper iodide and potassium sulphate?
Copper iodide is typically white to pale yellow, while potassium sulfate is typically colorless or white.
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?
When Potassium Iodide is added to Copper Chloride, a double displacement reaction occurs producing Potassium Chloride and Copper Iodide. The Copper Iodide formed is insoluble in water and precipitates out of the 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 happens when Potassium Iodide is added in Copper Chloride?
When Potassium Iodide is added to Copper Chloride, a double displacement reaction occurs producing Potassium Chloride and Copper Iodide. The Copper Iodide formed is insoluble in water and precipitates out of the solution.
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.
