Question

A student added few pieces of aluminium metal to toothpaste tubes A and B containing aqueous solution of iron sulphate and copper sulphate. In the second part of experiment see added iron metal to another test tube C and D containing at the solution of Aluminium Sulphate and copper sulphate.
In which test tubes are test tubes will be observed colour change? on the basis of this experiment state which one is the most reactive metal and why?

Answer 1

HEY MATE HERE IS YOUR ANSWER....



=======================


Colour change will occur in test tubes A, B and D..
Aluminium is most reactive metal as it displaces iron and copper both from their compounds.....

Answer 2

Test tubes in which change in colour occurred are:
Test tube A,B, D. Because in test tube A aluminium displaces iron due to iits high reactivity than iron
In test tube B aluminium displaces displaces the copper and form aluminium sulphate.
In test tube D iron is more reactive than copper so it displaces copper from copper sulphate solution and fades its colour gradually.
Hence we find iron and aluminium as reactive metals.
