Question

explain why the blue colour of copper sulphate solution fades when an iron nail is kept dipped in it? write chemical equation of the reaction involved what does this reaction tell us about the relative reactivity of Copper and iron.​

Answer 1

Answer:

Explanation:

It is so because iron nail displaces the copper from copper sulphate solution.

Since iron is more reactive than copper therefore it displaces the copper and the colour fades.

Cuso4 + fe---------->FeSo4 + Cu

It tells iron is more reactive than copper.
