Question

what happens when we mix copper sulphate with iron

Answer 1

Answer:

No reaction takes place as copper is less reactive than iron

Answer 2

Answer:

Explanation:

When a silvery iron bar is put in a copper sulfate solution, the solution slowly starts to change color – the bright blue color gradually turns green (the salt FeSO₄ which forms in replacement has a green color). Metallic copper of a reddish color also starts to form around the dissolving iron bar.
