Why does the colour of copper sulphate solution change when an iron nail is dipped in it? Write two observations.

Answered by admin @ 11/08/2021

Answer:

The copper from the solution is transferred to the nail, therefore, the colour of the solution changes

Explanation:

When an iron nail is dipped into copper sulphate solution, iron, being the more reactive material, attracts the copper from the copper sulphate, which deposits on the iron nail, and the copper sulphate solution, now with no copper turns pale green.
