why do the colour and solution of copper sulphate change when we take a solution of copper sulphate in a beaker and put iron nail in it
Answers
Answer:
The colour and solution of copper sulphate change when we take a solution of copper sulphate in a beaker and put iron nail in it because iron is more reactive than copper so it displace copper from copper sulphate and forms iron sulphate.
The chemical equation can be written as:
Fe+CuSO4→Cu+FeSO4.
When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green.

pls mark me the brainliest.......
Answer:
Because Iron is more reactive than copper so it displaces copper from the molecules and turns it from copper sulphate to Iron (ferrous) sulphate . this reaction is called the displacement reaction
