What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
What happens when a silver spoon is kept immersed in aqueous copper sulphate solution?
When a silver spoon is immersed in aqueous copper sulphate solution, a displacement reaction occurs. The silver spoon will react with the copper sulphate, displacing the copper ions and forming silver sulphate solution. Over time, the silver spoon will start to turn slightly reddish as a thin layer of copper is deposited on its surface.
What changes in the colour of iron nails and coppper sulphate solution do you observe after keeping the iron nails in copper sulphate solution for about half an hour?
After keeping iron nails in a copper sulfate solution for about half an hour, you will observe that the color of the iron nails changes to a reddish-brown due to the deposition of copper on the surface of the nails. The blue color of the copper sulfate solution will fade as copper is transferred from the solution to the nails.
What two colour changes do you get when you add copper sulphate solution to iron wool?
When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
Why does the color of copper sulphate change when an iron nail dipped in it?
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.

Can copper sulphate be separated from its solution by crystallization?
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
What two colour changes do you get when you add copper sulphate solution to iron wool?
When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.
What color is copper sulphate solution and water mixture?
Copper sulphate's colour is blue.
How do you prepare copper sulphate solution?
Add anhydrous copper sulphate to distilled water.
What would be seen coating the zinc strips in the reaction zinc and iron sulphate?
Hi there, I am not very sure what the coating is called but i think it is iron oxide. lolxx
What forms a solution?
copper sulphate
What is the formula for Copper Sulphate for testing for presence of Stainless Steel?
The formula for Copper Sulphate is CuSO4. To test for the presence of stainless steel, you can immerse the suspected stainless steel object in a solution of Copper Sulphate. If the object is not stainless steel and contains iron, a red-brown coating of copper will form on the object due to a displacement reaction between iron and copper ions in the solution.
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
