Question

With the help of an activity show that iron is more reactive than copper

Answer 1

I don't know if you have any questions

Answer 2

To show that iron is more reactive than copper-

• At first prepare a solution of copper sulphate by dissolving copper sulphates crystals in water.
• We will get a blue colored solution.
• Now, keep an iron nail dipped in this solution.
• After sometime we will see that the colour of solution changes to dirty green and a reddish-brown powder sticks to the nail.
• Copper in copper sulphate is displaced by iron of the nail, and iron sulphate is formed which is green in colour.
• Thus, it shows that iron is more reactive than copper.

The reaction can be written as-

$\rm { Fe_{(iron)} + CuSO_{4(copper \: sulphate)} \longrightarrow FeSo_{4(iron \: sulphate)} + Cu }$
