Because a displacement reaction has occured
Copper sulphate's colour is blue.
The blue color of the copper sulfate solution turns green when an iron nail is added because a chemical reaction occurs where iron displaces copper in the solution, forming iron sulfate and copper metal. The green color is due to the presence of copper metal particles in the solution.
Why does the colour of copper sulphate solution change when an iron nail is 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.
There would be copper deposited in the piece of iron and the solution would show a color change from pale blue to pale green.
An aqueous solution of copper sulfate absorbs light in the blue-green region of the spectrum. This is because copper ions in the solution absorb light of longer wavelength, leaving behind the blue-green color.
Copper sulphate is a blue coloured solution. As soon as you react it with iron, you will notice that the solution is turning into light green which means iron sulphate solution is forming. Iron being more reactive than copper displaces copper from its soluion.
Yes, Copper Sulphate crystals can dissolve in water to form a blue 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)
When copper sulphate reacts with iron, the solution turns blue due to the formation of copper ions in the solution. This is because copper is displaced from the copper sulfate and iron sulfate is formed, leading to the blue color of the solution.
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.
When copper sulfate is dissolved in water, it dissociates into copper ions (Cu2+) and sulfate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water. The solution can conduct electricity due to the presence of free ions.
