Why does the colour of copper sulphate solution change when an iron nail is dipped in it ?

Question

Answer

When an iron nail is dipped in copper sulphate solution as we know that iron is more reactive than copper as a result displacement reaction take place the reaction can be represented as:
Cuso4+Fe=Feso4+Cu,
in this reaction blue colour of copper sulphate solution changes to green colour of iron sulphate

Answer

Due to the Displacement Reaction, Copper in the Copper Sulphate solution collects over Iron. So colour of Copper Sulphate solution fades.

Answer

Iron is more reactive than copper so iron displaces copper from its salt solution.The blue colour of copper sulphate solution changes into green in colour and we can see brownish deposits on the iron nail.It is an example of displacement reaction.

Answer

Why does the colour of copper sulphate solution change when an iron nail is dipped in it?

Introduction

Copper sulphate is a blue coloured salt that dissolves in water to form a blue coloured solution. When an iron nail is dipped in the solution, the colour of the solution changes to green. This change in colour is due to a chemical reaction that occurs between the iron nail and the copper sulphate solution.

Chemical Reaction

The chemical reaction that occurs between the iron nail and the copper sulphate solution is a redox reaction. In this reaction, iron reacts with copper ions in the solution to form iron ions and copper metal.

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)

Explanation

When the iron nail is dipped in the copper sulphate solution, the iron atoms on the surface of the nail react with the copper ions in the solution. This reaction causes the copper ions to lose electrons and form copper metal, which is deposited on the surface of the iron nail. At the same time, the iron atoms on the surface of the nail lose electrons and form iron ions, which dissolve in the solution.

As the copper metal is deposited on the surface of the iron nail, the colour of the solution changes from blue to green. This is because the green colour of copper metal is reflected in the solution, giving it a greenish tint.

Conclusion

In conclusion, the colour of copper sulphate solution changes when an iron nail is dipped in it due to a chemical reaction between the iron nail and the copper ions in the solution. This reaction causes the formation of copper metal on the surface of the iron nail, which gives the solution a greenish tint.

Answer

Blue colour of the copper sulphate solution changes into green colour & then iron nail acquires a brownish look. This is because that iron is more reactive than copper. The following chemical reaction takes place in this activity. In this reaction, iron displaces copper from CuSO4 solution.

Answer

Answer

Copper Sulphate Solution (CuSO4) is blue in colour. When iron nail is placed in it, we can observe ---->

1) reddish brown deposits on iron (these are of Copper)

2) colour of the solution turns from blue to light green.

The formula for this reaction is: Fe + CuSO4 --> FeSO4 + Cu

Here, Fe is more reactive than Cu. So Fe displaces Cu to form Iron Sulfate and Copper.

Answer

due to the formation of iron sulphate(a new substance)in which copper is displaced with iron.reaction-CuSO4 + Fe= FeSO4 + Cu

Answer

When an iron nail is dipped in copper sulphate, its colour changes because the sulphur in the copper sulphate reacts with the iron to form a new substance, iron sulphate which is green in colour.

Answer

Iron, that is more reactive than copper, displaces it from its sulphate salt solution by displacement reaction.following happens:Fe+CuSO4= FeSO4+Cu

Answer

because of displacement reaction.As we know iron is more reactive than  copper and the displacement reaction state that more reactive  metal displaces less reactive metal from its compound or salt solution. therefore when we put iron nail in cuso4 solution then iron displaces the cu. the reaction is Fe +cuso4 ÷ feso4  +cu . at last when reaction takes place then colour of solution changes because the Fe and cu have different properties  related to colors

Answer

because  there  is displacement  reaction  between iron  and copper sulphate

Answer

When we dipped a nail in coppee sulphate solution thn iron is more reactive thn cu so fe  displace the cu nd formed feso4 in product..... In this reaction we saw that the colour is change colour is redish brown

Answer

green

Answer

displacement reaction takes place
