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

What will happen when iron nails dipped in copper sulphate solution?

What happens if you put an iron nail in copper sulphate solution? Describe how do you perform this activity.

What is the reason for the change in colour of copper sulphate when iron nail is kept on it ?

If the key is to be coated with aluminium instead of copper, what changes do we need to make in the experiment of coating on iron key with copper?

A solution of copper sulphate is electrolysed using a current strength of 3 amp to deposite 60 grams of copper. What is the time taken for the electrolysis?

An electric current is passed through silver nitrate soultion using silver electrodes. 10.79 g of silver was found to be deposited on the cathode if the same amount of electricity is passed through copper sulphate solution using copper electrodes, the weight of copper deposited on the cathode is
