Question

when iron nail is kept immersed in copper sulphate solution for sometime a brown coating is formed on iron rod. What changes will be observed in the color of the solution? also write the chemical equation for the reaction involved

Answer 1

The color of the solution changes from blue (CuSO4) to light green (FeSO4).

Reaction:-

Fe(s) + CuSO4(l) gives FeSO4(l) + Cu

(blue) (green)

Answer 2

The changes we observe in the colour of solution is iron in cuso4 solution becomes brown which denotes that iron is more reactive than Cu.

Balanced Chemical equation⤵⤵

CuSO4 + Fe =》FeSO4 + Cu.
