Aqueous solution of ammonium sulphate

The aqueous solution of Aluminium Sulphate is

Aqueous solution of copper sulphate

Is it possible to extract Al by the electrolysis of an aqueous solution of aluminium sulphate? Explain.

A student addd few pieces of aluminium metal to two test tubes A and B containing aqueous solutions of iron sulphate and copper sulphate. In the second part of her experiment, the added iron metal to another test tubes C and D containing aqueous solutions of aluminium sulphate and copper sulphate. In which test tube or test tubes will she observe colour change? On the basis of this experiment, state which one is the most reactive metal and why ?
