What did happen when you put iron nail in copper sulphate solution ?

Question

Answer

When iron nail is dipped in copper sulphate there takes reaction between them and coppersulphate change its colour from blue to light green this show iron is more reactive than copper it can replace from CuSo4,CuSo4 is in blue colour and FeSo4  is in light green colour

Answer

When Iron nail is placed in copper sulphate solutions it forms Iron sulphate and Copper is replaced.
Iron nail + copper sulphate -: Iron sulphate + Copper

Answer

There will be change in the composition and colour of the solution (from blue to light green)....

Answer

When we put an iron nail in the solution it turns into green and the nail gets a brown coating that is the sulphur deposit. The solution becones FeSO4 that is iron sulphate solution which is green in colour.

Answer

There is a red Brown layer of copper metal on the iron nail and the solution changes its color   from blue to light green

Answer

A Displacement reaction takes place........

Answer

Copper is displaced and forms Iron sulphate

Answer

When you put an iron nail in a copper sulphate solution, a series of chemical reactions occur. Let's delve into the details of what happens during this process.

1. Introduction
When the iron nail is immersed in the copper sulphate solution, the iron and copper sulphate react with each other, resulting in a displacement reaction.

2. Displacement Reaction
The iron nail, being more reactive than copper, displaces the copper ions in the copper sulphate solution. This displacement reaction can be represented by the following chemical equation:
Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)

3. Formation of Iron (II) Sulphate
During the displacement reaction, the iron from the nail combines with the sulphate from the copper sulphate solution, forming iron (II) sulphate. This compound is soluble in water and remains in the solution.
Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)

4. Formation of Copper
Simultaneously, the copper ions from the copper sulphate solution are displaced by the iron and are deposited onto the surface of the nail. This deposition of copper results in the formation of a reddish-brown coating on the iron nail.
Fe (s) + CuSO4 (aq) → FeSO4 (aq) + Cu (s)

5. Observation
As the reaction progresses, you will observe the following changes:
- The iron nail starts to lose its metallic luster.
- The blue color of the copper sulphate solution fades.
- A reddish-brown coating of copper starts to form on the surface of the iron nail.

6. Conclusion
In conclusion, when an iron nail is placed in a copper sulphate solution, a displacement reaction occurs. The iron displaces the copper ions from the solution, resulting in the formation of iron (II) sulphate in the solution. Simultaneously, the displaced copper ions are deposited onto the surface of the iron nail, leading to the formation of a reddish-brown coating. This reaction demonstrates the reactivity series, where a more reactive metal can displace a less reactive metal from its compound.
